Investigating the Stacked Phonetic Bottleneck Feature for Speaker Verification with Short Voice Commands

2017

Text-dependent speaker verification (SV) with short voice command (SV-SVC) has increasing demand in many applications. Different from conventional SV, SV-SVC usually uses short fixed voice commands for user-friendly purpose, which causes technical challenges compared with …

Self-supervised Contrastive Cross-Modality Representation Learning for Spoken Question Answering

2021

Spoken question answering (SQA) requires fine-grained understanding of both spoken documents and questions for the optimal answer prediction. In this paper, we propose novel training schemes for spoken question answering with a self-supervised training stage …

Learning Decoupling Features Through Orthogonality Regularization

2022 · ICASSP 2022 - 2022 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP)

Keyword spotting (KWS) and speaker verification (SV) are two important tasks in speech applications. Research shows that the state-of-art KWS and SV models are trained independently using different datasets since they expect to learn distinctive …

Accelerating Multiple Intent Detection and Slot Filling via Targeted Knowledge Distillation

2023

Recent non-autoregressive Spoken Language Understanding (SLU) models have attracted increasing attention because of their encouraging inference speed. However, most of existing methods (1) suffer from the multi-modality problem since they have little prior knowledge about …
