EMOTIONAL DIMENSION CONTROL IN LANGUAGE MODEL-BASED TEXT-TO-SPEECH: SPANNING A BROAD SPECTRUM OF HUMAN EMOTIONS

ICASSP 2026poster

Emotional text-to-speech (TTS) systems sturggle to capture the full spectrum of human emotions due to the inherent complexity of emotional expressions and the limited coverage of existing emotion labels. To address this, we propose a language model-based TTS framework that synthesizes speech across…

Multi-band Frequency Reconstruction for Neural Psychoacoustic Coding

ICML 2025poster

Achieving high-fidelity audio compression while preserving perceptual quality across diverse audio types remains a significant challenge in Neural Audio Coding (NAC). This paper introduces MUFFIN, a fully convolutional NAC framework that leverages psychoacoustically guided multi-band frequency recon…

MossFormer2: Combining Transformer and RNN-Free Recurrent Network for Enhanced Time-Domain Monaural Speech Separation

ICASSP 2024accepted

Our previously proposed MossFormer has achieved promising performance in monaural speech separation. However, it predominantly adopts a self-attention-based MossFormer module, which tends to emphasize longer-range, coarser-scale dependencies, with a deficiency in effectively modelling finer-scale re…

SPGM: Prioritizing Local Features for Enhanced Speech Separation Performance

ICASSP 2024accepted

Dual-path is a popular architecture for speech separation models (e.g. Sepformer) which splits long sequences into overlapping chunks for its intra- and inter-blocks that separately model intra-chunk local features and inter-chunk global relationships. However, it has been found that inter-blocks, w…

Adaptive Knowledge Distillation Between Text and Speech Pre-Trained Models

ICASSP 2023accepted

Learning on a massive amount of speech corpus leads to the recent success of many self-supervised speech models. With knowledge distillation, these models may also benefit from the knowledge encoded by language models that are pre-trained on rich sources of texts. The distillation process, however,…

Contrastive Speech Mixup for Low-Resource Keyword Spotting

ICASSP 2023accepted

Most of the existing neural-based models for keyword spotting (KWS) in smart devices require thousands of training samples to learn a decent audio representation. However, with the rising demand for smart devices to become more person-alized, KWS models need to adapt quickly to smaller user samples.…

De'hubert: Disentangling Noise in a Self-Supervised Model for Robust Speech Recognition

ICASSP 2023accepted

Existing self-supervised pre-trained speech models have offered an effective way to leverage massive unannotated corpora to build good automatic speech recognition (ASR). However, many current models are trained on a clean corpus from a single source, which tends to do poorly when noise is present d…

Intra-Inter Subject Self-Supervised Learning for Multivariate Cardiac Signals

AAAI 2022technical

Learning information-rich and generalizable representations effectively from unlabeled multivariate cardiac signals to identify abnormal heart rhythms (cardiac arrhythmias) is valuable in real-world clinical settings but often challenging due to its complex temporal dynamics. Cardiac arrhythmias can…
