FEW-SHOT AND PSEUDO-LABEL GUIDED SPEECH QUALITY EVALUATION WITH LARGE LANGUAGE MODELS

ICASSP 2026oral

In this paper, we introduce GatherMOS, a novel framework that leverages large language models (LLM) as meta-evaluators to aggregate diverse signals into quality predictions. GatherMOS integrates lightweight acoustic descriptors with pseudo-labels from DNSMOS and VQScore, enabling the LLM to reason o…

Developing Instruction-Following Speech Language Model Without Speech Instruction-Tuning Data

ICASSP 2025accepted

Recent end-to-end speech language models (SLMs) have expanded upon the capabilities of large language models (LLMs) by incorporating pre-trained speech models. However, these SLMs often undergo extensive speech instruction-tuning to bridge the gap between speech and text modalities. This requires si…

Generative Speech Foundation Model Pretraining for High-Quality Speech Extraction and Restoration

ICASSP 2025accepted

This paper proposes a generative pretraining foundation model for high-quality speech restoration tasks. By directly operating on complex-valued short-time Fourier transform coefficients, our model does not rely on any vocoders for time-domain signal reconstruction. As a result, our model simplifies…

RankUp: Boosting Semi-Supervised Regression with an Auxiliary Ranking Classifier

NeurIPS 2024poster

State-of-the-art (SOTA) semi-supervised learning techniques, such as FixMatch and it's variants, have demonstrated impressive performance in classification tasks. However, these methods are not directly applicable to regression tasks. In this paper, we present RankUp, a simple yet effective approach…

Self-Supervised Speech Quality Estimation and Enhancement Using Only Clean Speech

ICLR 2024poster

Speech quality estimation has recently undergone a paradigm shift from human-hearing expert designs to machine-learning models. However, current models rely mainly on supervised learning, which is time-consuming and expensive for label collection. To solve this problem, we propose VQScore, a self-su…

Real-Time Speech Interruption Analysis: from Cloud to Client Deployment

ICASSP 2023accepted

Meetings are an essential form of communication for all types of organizations, and remote collaboration systems have been much more widely used since the COVID-19 pandemic. One major issue with remote meetings is that it is challenging for remote participants to interrupt and speak. We have recentl…

MetricGAN-U: Unsupervised Speech Enhancement/ Dereverberation Based Only on Noisy/ Reverberated Speech

ICASSP 2022accepted

Most of the deep learning-based speech enhancement models are learned in a supervised manner, which implies that pairs of noisy and clean speech are required during training. Consequently, several noisy speeches recorded in daily life cannot be used to train the model. Although certain unsupervised…

MetricGAN: Generative Adversarial Networks based Black-box Metric Scores Optimization for Speech Enhancement

ICML 2019oral

Adversarial loss in a conditional generative adversarial network (GAN) is not designed to directly optimize evaluation metrics of a target task, and thus, may not always guide the generator in a GAN to generate data with improved metric scores. To overcome this issue, we propose a novel MetricGAN ap…
