SimulS2ST-Omni: Data-Efficient Streaming Speech-to-Speech Translation via Explicit Trajectory Supervision

Rongshen He, Xinyu Liang, Dekun Chen +3

Long-form streaming speech-to-speech translation (S2ST) requires incremental, unbounded translation under strict latency constraints. Existing methods typically suffer from sentenc…

CHILDES-Aligned: A Curated Children's Speech Dataset via Multi-Model Timestamp Ensembling

Haolong Zheng, Yuanzhuo Hu, Xinyu Liang +7

CHILDES is a large-scale child speech corpus containing long-form recordings of naturalistic child-adult interactions, making it a valuable resource for studying child speech and l…

DNSMOS-C: Improving End-to-end Speech Quality Models via Contrastive Learning

Xinyu Liang, Fredrik Cumlin, Victor Ungureanu +3

We introduce DNSMOS-C, a compact end-to-end speech quality assessment model that extends the DNSMOS Pro framework by integrating a MOS-guided triplet-based contrastive loss. Applie…

FlexiSLM: A Spoken Language Model with Dynamic and Controllable Frame Rates

Jiaqi Li, Chaoren Wang, Xiaohai Tian +9

Spoken language models (SLMs) extend LLMs to speech input and output, but existing systems use fixed frame rates (e.g., 25 or 12.5 Hz), overlooking speech's time-varying informatio…

SA-SSL-MOS: Self-supervised Learning MOS Prediction with Spectral Augmentation for Generalized Multi-Rate Speech Assessment

Fengyuan Cao, Xinyu Liang, Fredrik Cumlin +4

Designing a speech quality assessment (SQA) system for estimating mean-opinion-score (MOS) of multi-rate speech with varying sampling frequency (16-48 kHz) is a challenging task. T…

Selection of Layers from Self-supervised Learning Models for Predicting Mean-Opinion-Score of Speech

Xinyu Liang, Fredrik Cumlin, Victor Ungureanu +3

Self-supervised learning (SSL) models like Wav2Vec2, HuBERT, and WavLM have been widely used in speech processing. These transformer-based models consist of multiple layers, each c…

Leveraging LLMs for Scalable Non-intrusive Speech Quality Assessment

Fredrik Cumlin, Xinyu Liang, Anubhab Ghosh +1

Non-intrusive speech quality assessment (SQA) systems suffer from limited training data and costly human annotations, hindering their generalization to real-time conferencing calls…

Multivariate Probabilistic Assessment of Speech Quality

Fredrik Cumlin, Xinyu Liang, Victor Ungureanu +3

The mean opinion score (MOS) is a standard metric for assessing speech quality, but its singular focus fails to identify specific distortions when low scores are observed. The NISQ…

Impairments are Clustered in Latents of Deep Neural Network-based Speech Quality Models

Fredrik Cumlin, Xinyu Liang, Victor Ungureanu +3

In this article, we provide an experimental observation: Deep neural network (DNN) based speech quality assessment (SQA) models have inherent latent representations where many type…
