Text-based speech editing aims to modify specific segments while preserving speaker identity and acoustic context. Existing methods rely on task-specific training, which incurs high data costs and struggles with temporal fidelity in unedited regions. Meanwhile, adapting Text-to-Speech (TTS) models often faces a trade-off between editing quality and consistency. To address these issues, we propose AST, an Adaptive, Seamless, and Training-free precise speech editing framework. Leveraging a pre-trained autoregressive TTS model, AST introduces Latent Recomposition to selectively stitch preserved source segments with newly synthesized targets. Furthermore, AST extends this latent manipulation to enable precise style editing for specific speech segments. To prevent artifacts at these edit boundaries, the framework incorporates Adaptive Weak Fact Guidance (AWFG). AWFG dynamically modulates a mel-space guidance signal, enforcing structural constraints only where necessary without disrupting the generative manifold. To fill the gap of publicly accessible benchmarks, we introduce LibriSpeech-Edit, a new and larger speech editing dataset. As existing metrics poorly evaluate temporal consistency in unedited regions, we propose Word-level Dynamic Time Warping (WDTW). Extensive experiments demonstrate that AST resolves the controllability-quality trade-off without extra training. Compared to the previous most temporally consistent baseline, AST improves consistency while reducing Word Error Rate by nearly 70%. Moreover, applying AST to a foundation TTS model reduces WDTW by 27%, achieving state-of-the-art speaker preservation and temporal fidelity.

The proposed AST framework introduces a novel approach to speech editing by leveraging latent space manipulation from pre-trained TTS models, which is a significant departure from traditional task-specific training methods. The incorporation of Adaptive Weak Fact Guidance (AWFG) to manage edit boundaries and maintain acoustic fidelity is particularly innovative. The methodology is well-structured, with clear stages for input inversion, alignment, and generation, making it easy to follow and replicate.

The experiments are extensive and well-designed, utilizing a new dataset (LibriSpeech-Edit) that addresses previous limitations in speech editing benchmarks. The paper provides a thorough comparison against established baselines, demonstrating significant improvements in key metrics such as Word Error Rate (WER) and Word-level Dynamic Time Warping (WDTW). The results indicate that AST not only matches but often surpasses the performance of models specifically trained for speech editing, showcasing its effectiveness.
The paper includes detailed implementation details, including the experimental setup and evaluation metrics, which enhances reproducibility. However, the lack of publicly available code or a demo URL limits the ability for other researchers to directly replicate the results. The introduction of a new dataset is a positive step towards facilitating reproducibility in future work.
While the AST framework shows promise, it may still face challenges in more complex editing scenarios that involve significant alterations to the speech content. The reliance on a pre-trained TTS model may also limit the adaptability of the framework to other TTS architectures. Additionally, the subjective evaluation of audio quality and naturalness could benefit from further exploration through user studies.
The implications of this research are substantial, particularly for applications in media production, accessibility, and content creation. By enabling precise speech editing without the need for extensive training data, AST could democratize access to high-quality speech editing tools, fostering innovation in various fields such as entertainment, education, and assistive technologies.

Universal speech enhancement (USE) aims to restore speech signals from diverse distortions across multiple sampling rates. We propose UniPASE, an extension of the low-hallucination PASE framework tailored for USE. At its core is DeWavLM-Omni, a unified representation-level enhancement module fine-tuned from WavLM via knowledge distillation on a large-scale supervised multi-distortion dataset. This module directly converts degraded waveforms into clean and linguistically faithful phonetic representations, ensuring robust enhancement with minimal linguistic hallucination. Based on these enhanced phonetic representations, an Adapter generates enhanced acoustic representations containing rich acoustic details, which a neural Vocoder uses to reconstruct corresponding high-fidelity 16-kHz waveforms. A PostNet then converts the waveforms to 48~kHz before resampling them to their original rates, enabling seamless handling of inputs and outputs at multiple sampling rates. Experimental results on several evaluation datasets, covering sub-tasks and full tasks, demonstrate that UniPASE achieves superior or competitive performance compared with existing state-of-the-art models. The proposed model also serves as the backbone of our submission to the URGENT 2026 Challenge, which achieved 1st place in the objective evaluation.

In bandwidth-constrained communication such as satellite and underwater channels, speech must often be transmitted at ultra-low bitrates where intelligibility is the primary objective. At such extreme compression levels, codecs trained with acoustic reconstruction losses tend to allocate bits to perceptual detail, leading to substantial degradation in word error rate (WER). This paper proposes ClariCodec, a neural speech codec operating at 200 bit per second (bps) that reformulates quantisation as a stochastic policy, enabling reinforcement learning (RL)-based optimisation of intelligibility. Specifically, the encoder is fine-tuned using WER-driven rewards while the acoustic reconstruction pipeline remains frozen. Even without RL, ClariCodec achieves 3.68% WER on the LibriSpeech test-clean set at 200 bps, already competitive with codecs operating at higher bitrates. Further RL fine-tuning reduces WER to 3.20% on test-clean and 8.93% on test-other, corresponding to a 13% relative reduction while preserving perceptual quality.

ClariCodec presents a novel approach to neural speech coding by optimising for intelligibility at ultra-low bitrates using reinforcement learning. This work significantly advances the state of the art in speech codecs, addressing critical challenges in bandwidth-constrained communication environments while maintaining competitive performance metrics.
The methodology proposed in ClariCodec is innovative, particularly in its two-stage training approach that combines traditional reconstruction-based training with reinforcement learning (RL) for semantic optimisation. The reformulation of quantisation as a stochastic policy is a significant advancement, allowing for the direct optimisation of intelligibility using word error rate (WER) as a reward signal. This novel approach addresses the limitations of existing codecs that prioritize acoustic fidelity over intelligibility, making it a meaningful contribution to the field of neural speech coding.
The experimental evaluation is robust, utilizing the LibriSpeech dataset to benchmark performance against several existing neural speech codecs. The results demonstrate that ClariCodec achieves competitive performance at an unprecedented low bitrate of 200 bps, with a WER of 3.20% on test-clean and 8.93% on test-other. The paper includes comprehensive comparisons with baseline models, showing that ClariCodec maintains perceptual quality while achieving significant improvements in intelligibility through RL fine-tuning.
The paper provides detailed implementation information, including model architecture, training setup, and loss functions used in both stages of training. However, the lack of a publicly available code repository limits the reproducibility of the results. The authors mention using specific hardware and configurations, which could aid in reproducing the experiments if the code were available.
One limitation noted is the potential degradation in acoustic quality when optimising solely for intelligibility during the RL fine-tuning phase. The paper addresses this by incorporating a mel reconstruction loss to mitigate quality loss, but this trade-off remains a concern. Additionally, the non-causal architecture may introduce latency issues, which the authors plan to address in future work.
The implications of ClariCodec are significant, particularly for applications in bandwidth-constrained environments such as satellite and underwater communication. By prioritising intelligibility over acoustic fidelity, this codec could enhance communication reliability in critical scenarios. The potential for future developments, such as streaming codecs and integration with generative tasks, suggests a broad range of applications in speech technology. ClariCodec presents a novel approach to neural speech coding by optimising for intelligibility at ultra-low bitrates using reinforcement learning. This work significantly advances the state of the art in speech codecs, addressing critical challenges in bandwidth-constrained communication environments while maintaining competitive performance metrics.
Video-to-Speech (VTS) generation aims to synthesize speech from a silent video without auditory signals. However, existing VTS methods disregard the hierarchical nature of speech, which spans coarse speaker-aware semantics to fine-grained prosodic details. This oversight hinders direct alignment between visual and speech features at specific hierarchical levels during property matching. In this paper, leveraging the hierarchical structure of Residual Vector Quantization (RVQ)-based codec, we propose HiCoDiT, a novel Hierarchical Codec Diffusion Transformer that exploits the inherent hierarchy of discrete speech tokens to achieve strong audio-visual alignment. Specifically, since lower-level tokens encode coarse speaker-aware semantics and higher-level tokens capture fine-grained prosody, HiCoDiT employs low-level and high-level blocks to generate tokens at different levels. The low-level blocks condition on lip-synchronized motion and facial identity to capture speaker-aware content, while the high-level blocks use facial expression to modulate prosodic dynamics. Finally, to enable more effective coarse-to-fine conditioning, we propose a dual-scale adaptive instance layer normalization that jointly captures global vocal style through channel-wise normalization and local prosody dynamics through temporal-wise normalization. Extensive experiments demonstrate that HiCoDiT outperforms baselines in fidelity and expressiveness, highlighting the potential of discrete modelling for VTS. The code and speech demo are both available at https://github.com/Jiaxin-Ye/HiCoDiT.

Speech translation for low-resource languages remains fundamentally limited by the scarcity of high-quality, diverse parallel speech data, a challenge that is especially pronounced in African linguistic contexts. To address this, we introduce NaijaS2ST, a parallel speech translation dataset spanning Igbo, Hausa, Yorùbá, and Nigerian Pidgin paired with English. The dataset comprises approximately 50 hours of speech per language and captures substantial variation in speakers and accents, reflecting realistic multilingual and multi-accent conditions. With NaijaS2ST, we conduct a comprehensive benchmark of cascaded, end-to-end (E2E), and AudioLLM-based approaches across bidirectional translation settings. Our results show that audio LLMs with few-shot examples are more effective for speech-to-text translation than cascaded and end-to-end methods trained on fine-tuned data. However, for speech-to-speech translation, the cascaded and audio LLM paradigms yield comparable performance, indicating that there is still considerable room for improvement in developing targeted, task-specific models for this setting. By providing both a high-quality dataset and a systematic benchmark, we hope that NaijaS2ST will serve as a strong foundation for advancing research in low-resource, multilingual speech translation.

Music understanding and reasoning are central challenges in the Music Information Research field, with applications ranging from retrieval and recommendation to music agents and virtual assistants. Recent Large Audio-Language Models (LALMs) have shown remarkable progress in answering music-related questions by following user instructions. However, their massive scale, often billions of parameters, results in expensive training, slow inference, and limited deployability on edge devices. In this work, we present TinyMU, a lightweight (229M) Music-Language Model (MLM) that achieves performance comparable to much larger LALMs while remaining efficient and compact. To train TinyMU, we introduce MusicSkills-3.5M, a carefully curated, music-grounded question-answering dataset with 3.5M samples. Spanning multiple-choice, binary, and open-ended formats, this dataset provides fine-grained supervision across diverse musical concepts. For its architecture, TinyMU leverages MATPAC++, the SOTA self-supervised audio encoder for fine-grained feature extraction. Paired with a lightweight linear projector, it efficiently aligns audio embeddings with the language model. Through extensive evaluation, we show that TinyMU performs strongly in both basic music understanding and complex reasoning. Notably, on the MuChoMusic benchmark, it achieves 82\% of SOTA LALM's performance despite being 35x smaller, highlighting the potential of small MLMs under constrained computational budgets.

Recent end-to-end spoken dialogue models enable natural interaction. However, as user demands become increasingly complex, models that rely solely on conversational abilities often struggle to cope. Incorporating agentic capabilities is therefore essential: by enabling tool use, these models can extend their knowledge boundaries and better solve real-world tasks. Yet, existing research has largely concentrated on core perception and generation, with comparatively limited exploration of such tool-augmented extensions. To bridge this gap, we present VoxMind, an integrated framework designed to equip end-to-end spoken dialogue models with comprehensive agentic abilities. Leveraging our curated 470-hour AgentChat dataset, we incorporate a "Think-before-Speak" mechanism, enabling the model to internalize structured reasoning as a critical prerequisite for planning and response generation. Furthermore, to mitigate latency bottlenecks caused by large-scale tool integration, we propose a Multi-Agent Dynamic Tool Management architecture. By asynchronously delegating retrieval tasks to an auxiliary agent aligned with the main model's reasoning trajectory, this system effectively decouples inference latency from toolset size. Experimental results confirm that VoxMind achieves significant improvements in agent performance: compared with strong baselines, the task completion rate increases from 34.88% to 74.57%, outperforming Gemini-2.5-Pro on spoken agent tasks while preserving general conversational quality.

Non-verbal vocalizations (NVVs) like laugh, sigh, and sob are essential for human-like speech, yet standardized evaluation remains limited in jointly assessing whether systems can generate the intended NVVs, place them correctly, and keep them salient without harming speech. We present Non-verbal Vocalization Benchmark (NVBench), a bilingual (English/Chinese) benchmark that evaluates speech synthesis with NVVs. NVBench pairs a unified 45-type taxonomy with a curated bilingual dataset and introduces a multi-axis protocol that separates general speech naturalness and quality from NVV-specific controllability, placement, and salience. We benchmark 15 TTS systems using objective metrics, listening tests, and an LLM-based multi-rater evaluation. Results reveal that NVVs controllability often decouples from quality, while low-SNR oral cues and long-duration affective NVVs remain persistent bottlenecks. NVBench enables fair cross-system comparison across diverse control interfaces under a unified, standardized framework.

Recent advances in video-to-audio (V2A) generation enable high-quality audio synthesis from visual content, yet achieving robust and fine-grained controllability remains challenging. Existing methods suffer from weak textual controllability under visual-text conflict and imprecise stylistic control due to entangled temporal and timbre information in reference audio. Moreover, the lack of standardized benchmarks limits systematic evaluation. We propose ControlFoley, a unified multimodal V2A framework that enables precise control over video, text, and reference audio. We introduce a joint visual encoding paradigm that integrates CLIP with a spatio-temporal audio-visual encoder to improve alignment and textual controllability. We further propose temporal-timbre decoupling to suppress redundant temporal cues while preserving discriminative timbre features. In addition, we design a modality-robust training scheme with unified multimodal representation alignment (REPA) and random modality dropout. We also present VGGSound-TVC, a benchmark for evaluating textual controllability under varying degrees of visual-text conflict. Extensive experiments demonstrate state-of-the-art performance across multiple V2A tasks, including text-guided, text-controlled, and audio-controlled generation.

Recent image-to-audio models have shown impressive performance on object-centric visual scenes. However, their application to satellite imagery remains limited by the complex, wide-area semantic ambiguity of top-down views. While satellite imagery provides a uniquely scalable source for global soundscape generation, matching these views to real acoustic environments with unique spatial structures is inherently difficult. To address this challenge, we introduce Geo2Sound, a novel task and framework for generating geographically realistic soundscapes from satellite imagery. Specifically, Geo2Sound combines structural geospatial attributes modeling, semantic hypothesis expansion, and geo-acoustic alignment in a unified framework. A lightweight classifier summarizes overhead scenes into compact geographic attributes, multiple sound-oriented semantic hypotheses are used to generate diverse acoustically plausible candidates, and a geo-acoustic alignment module projects geographic attributes into the acoustic embedding space and identifies the candidate most consistent with the candidate sets. Moreover, we establish SatSound-Bench, the first benchmark comprising over 20k high-quality paired satellite images, text descriptions, and real-world audio recordings, collected from the field across more than 10 countries and complemented by three public datasets. Experiments show that Geo2Sound achieves a SOTA FAD of 1.765, outperforming the strongest baseline by 50.0%. Human evaluations further confirm substantial gains in both realism (26.5%) and semantic alignment, validating our high-fidelity synthesis on scale.

The methodology presented in Geo2Sound is robust, integrating three key components—structural geospatial attributes modeling, semantic hypothesis expansion, and geo-acoustic alignment—into a cohesive framework. This approach effectively addresses the unique challenges posed by satellite imagery in soundscape generation. The use of a lightweight classifier for geographic attributes and the innovative semantic hypothesis expansion strategy significantly enhance the model's ability to produce diverse and contextually relevant soundscapes. The geo-acoustic alignment module further strengthens the framework by ensuring that the generated audio is not only acoustically plausible but also geographically consistent.
The experiments are comprehensive, utilizing a well-constructed benchmark (SatSound-Bench) with over 20k paired satellite images, textual descriptions, and audio recordings. The results demonstrate significant improvements over existing baselines, with both objective metrics (e.g., FAD, CLAP scores) and human evaluations indicating superior performance in terms of realism and semantic alignment. The thoroughness of the evaluation, including ablation studies, provides strong evidence for the contributions of each component of the framework.
The paper provides detailed implementation specifics, including the architecture of the models used, the training process, and the datasets employed. However, the absence of a demo URL limits immediate reproducibility for external researchers. The authors have made the project code available on GitHub, which is a positive aspect for reproducibility.
One limitation is the reliance on satellite imagery, which may not capture all acoustic nuances present in ground-level scenes. Additionally, the model's performance may vary based on the quality and resolution of the satellite images used. The paper does not discuss potential biases in the dataset or the implications of using field recordings from specific geographic locations.
The potential applications of Geo2Sound are significant, particularly in urban planning, environmental monitoring, and immersive media. By enabling the generation of realistic soundscapes from satellite imagery, this framework could facilitate better understanding and management of urban environments and promote public engagement with environmental issues. The integration of such technology into digital twin cities and virtual reality experiences could revolutionize how we interact with and perceive our surroundings.

Recent Large Audio Language Models have demonstrated impressive capabilities in audio understanding. However, they often suffer from perceptual errors, while reliable audio reasoning is unattainable without first grounding the model's perception in structured auditory scenes. Inspired by Auditory Scene Analysis, we first introduce a Perception-Aware Question Answering (PAQA) dataset. PAQA implements a hierarchical decoupling strategy that separates speech from environmental sound and distinguishes multiple speakers, providing explicit perceptual reasoning for training. Building on this, we propose HyPeR, a two-stage Hybrid Perception-Reasoning framework. In Stage I, we finetune the model on PAQA to perceive acoustic attributes in complex audio. In Stage II, we leverage GRPO to refine the model's internal deliberation. We also introduce PAUSE tokens to facilitate latent computation during acoustically ambiguous phases and design perceptual consistency reward to align reasoning rationales with raw audio. Experiments across benchmarks demonstrate that HyPeR achieves absolute improvements over the base model, with performance comparable to large-scale models, stressing the effectiveness of hybrid perception-grounded reasoning for robust and multi-speaker audio understanding.

Real-world video creation often involves a complex reasoning workflow of selecting relevant shots from noisy materials, planning missing shots for narrative completeness, and organizing them into coherent storylines. However, existing benchmarks focus on isolated sub-tasks and lack support for evaluating this full process. To address this gap, we propose Multimodal Context-to-Script Creation (MCSC), a new task that transforms noisy multimodal inputs and user instructions into structured, executable video scripts. We further introduce MCSC-Bench, the first large-scale MCSC dataset, comprising 11K+ well-annotated videos. Each sample includes: (1) redundant multimodal materials and user instructions; (2) a coherent, production-ready script containing material-based shots, newly planned shots (with shooting instructions), and shot-aligned voiceovers. MCSC-Bench supports comprehensive evaluation across material selection, narrative planning, and conditioned script generation, and includes both in-domain and out-of-domain test sets. Experiments show that current multimodal LLMs struggle with structure-aware reasoning under long contexts, highlighting the challenges posed by our benchmark. Models trained on MCSC-Bench achieve SOTA performance, with an 8B model surpassing Gemini-2.5-Pro, and generalize to out-of-domain scenarios. Downstream video generation guided by the generated scripts further validates the practical value of MCSC. Datasets are available at: https://github.com/huanran-hu/MCSC.

Large audio-language models (LALMs) generalize across speech, sound, and music, but unified decoders can exhibit a \emph{temporal smoothing bias}: transient acoustic cues may be underutilized in favor of temporally smooth context that is better supported by language priors, leading to less specific audio-grounded outputs. We propose \emph{Temporal Contrastive Decoding} (TCD), a training-free decoding method for unified LALMs that mitigates this effect at inference time. TCD constructs a temporally blurred slow-path view by smoothing the input waveform and re-encoding it, then contrasts next-token logits from the original and slow-path views. The contrastive signal is applied as a token-level logit update restricted to a small candidate set. A self-normalized stability score sets the blur window and update scale, and a step-wise gate based on uncertainty and audio reliance activates the update only when needed. Experiments on MMAU and AIR-Bench show consistent improvements on strong unified LALMs. We further conduct ablations and an architectural applicability study to analyze the contributions of key components and how TCD behaves across large audio-language model designs.

The paper introduces Temporal Contrastive Decoding (TCD), a novel training-free method that enhances the performance of large audio-language models by addressing temporal smoothing bias through a contrastive approach at inference time. The work is significant as it not only improves model accuracy but also provides a framework for future research into temporal audio processing techniques.
The proposed Temporal Contrastive Decoding (TCD) method innovatively addresses the temporal smoothing bias in large audio-language models (LALMs) by introducing a training-free decoding approach that contrasts original audio logits with a temporally blurred version. The methodology is well-structured, utilizing a self-normalized stability score to guide the blur window and update scale, and a gated mechanism to activate updates based on audio reliance and uncertainty. This careful design allows for targeted corrections during inference without modifying model parameters, which is a significant advantage in practical applications.
The experiments conducted on MMAU and AIR-Bench demonstrate consistent performance improvements across various unified LALMs, showcasing the effectiveness of TCD in enhancing audio understanding and reasoning capabilities. The ablation studies provide valuable insights into the contributions of different components of TCD, reinforcing the robustness of the proposed method. The results are statistically significant and indicate a clear advantage of TCD over existing methods like Audio-Aware Decoding.
The paper provides detailed implementation details and hyperparameter settings, which facilitate reproducibility. However, the reliance on specific architectures and the need for an additional forward pass for the slow-path view may complicate the implementation for some researchers.
One limitation is the additional computational overhead introduced by the extra forward pass required for the slow-path view, which could impact real-time applications. Additionally, TCD's effectiveness is contingent on the architecture of the LALMs, as it performs best with unified models that maintain access to temporally ordered audio representations. Models that compress audio too heavily may not benefit as much from TCD.
The TCD method has the potential to significantly improve the performance of audio-language models in various applications, including audio question answering, sound event detection, and multimodal interactions. By enhancing the model's ability to utilize transient acoustic cues, TCD could lead to more accurate and contextually relevant outputs in real-world scenarios. This advancement could facilitate further research into inference-time techniques that leverage temporal structures in audio processing.

As speech language models (SLMs) transition from personal devices into shared, multi-user environments, their responses must account for far more than the words alone. Who is speaking, how they sound, and where the conversation takes place can each turn an otherwise benign request into one that is unsafe, unfair, or privacy-violating. Existing benchmarks, however, largely focus on basic audio comprehension, study individual risks in isolation, or conflate content that is inherently harmful with content that only becomes problematic due to its acoustic context. We introduce VoxSafeBench, among the first benchmarks to jointly evaluate social alignment in SLMs across three dimensions: safety, fairness, and privacy. VoxSafeBench adopts a Two-Tier design: Tier1 evaluates content-centric risks using matched text and audio inputs, while Tier2 targets audio-conditioned risks in which the transcript is benign but the appropriate response hinges on the speaker, paralinguistic cues, or the surrounding environment. To validate Tier2, we include intermediate perception probes and confirm that frontier SLMs can successfully detect these acoustic cues yet still fail to act on them appropriately. Across 22 tasks with bilingual coverage, we find that safeguards appearing robust on text often degrade in speech: safety awareness drops for speaker- and scene-conditioned risks, fairness erodes when demographic differences are conveyed vocally, and privacy protections falter when contextual cues arrive acoustically. Together, these results expose a pervasive speech grounding gap: current SLMs frequently recognize the relevant social norm in text but fail to apply it when the decisive cue must be grounded in speech.

The paper introduces VoxSafeBench, a novel benchmark designed to evaluate speech language models (SLMs) across three critical dimensions: safety, fairness, and privacy, using a Two-Tier design. The methodology is robust, employing a comprehensive evaluation suite of 22 tasks that effectively distinguishes between content-centric risks and audio-conditioned risks. The inclusion of intermediate perception probes to validate the Tier 2 tasks is particularly noteworthy, as it demonstrates a thoughtful approach to isolating the effects of audio context on model behavior.

The use of bilingual coverage (English and Chinese) adds depth to the evaluation, making the findings more generalizable across different language contexts. The statistical rigor applied in the analysis of results, including the use of reference upper bounds, strengthens the validity of the findings.
The paper provides a thorough account of the dataset construction, evaluation model selection, and metric definitions, which are essential for reproducing the results. The authors have made their code and data publicly available, which is a significant step towards ensuring reproducibility in the research community. The detailed descriptions of the experimental setup, including the prompts used for evaluation, further enhance the reproducibility of the study.
The authors acknowledge several limitations, including the reliance on synthesized audio rather than natural speech, which may not fully capture the nuances of real-world interactions. Additionally, the Tier 2 tasks utilize deliberately prominent cues, which may not reflect subtler cues encountered in practice. The text-only upper bounds may not represent true oracle performance, indicating potential gaps in the evaluation framework.
