Beyond Universal Transformer: block reusing with adaptor in Transformer for automatic speech recognition

no code implementations23 Mar 2023 Haoyu Tang, Zhaoyi Liu, Chang Zeng, Xinfeng Li

To overcome the drawback of universal Transformer models for the application of ASR on edge devices, we propose a solution that can reuse the block in Transformer models for the occasion of the small footprint ASR system, which meets the objective of accommodating resource limitations without compromising recognition accuracy.

Cross-modal Audio-visual Co-learning for Text-independent Speaker Verification

1 code implementation22 Feb 2023 Meng Liu, Kong Aik Lee, Longbiao Wang, Hanyi Zhang, Chang Zeng, Jianwu Dang

Visual speech (i. e., lip motion) is highly related to auditory speech due to the co-occurrence and synchronization in speech production.

Joint Speaker Encoder and Neural Back-end Model for Fully End-to-End Automatic Speaker Verification with Multiple Enrollment Utterances

no code implementations1 Sep 2022 Chang Zeng, Xiaoxiao Miao, Xin Wang, Erica Cooper, Junichi Yamagishi

Conventional automatic speaker verification systems can usually be decomposed into a front-end model such as time delay neural network (TDNN) for extracting speaker embeddings and a back-end model such as statistics-based probabilistic linear discriminant analysis (PLDA) or neural network-based neural PLDA (NPLDA) for similarity scoring.

Spoofing-Aware Attention based ASV Back-end with Multiple Enrollment Utterances and a Sampling Strategy for the SASV Challenge 2022

no code implementations1 Sep 2022 Chang Zeng, Lin Zhang, Meng Liu, Junichi Yamagishi

Current state-of-the-art automatic speaker verification (ASV) systems are vulnerable to presentation attacks, and several countermeasures (CMs), which distinguish bona fide trials from spoofing ones, have been explored to protect ASV.

Attention Back-end for Automatic Speaker Verification with Multiple Enrollment Utterances

1 code implementation4 Apr 2021 Chang Zeng, Xin Wang, Erica Cooper, Xiaoxiao Miao, Junichi Yamagishi

Probabilistic linear discriminant analysis (PLDA) or cosine similarity have been widely used in traditional speaker verification systems as back-end techniques to measure pairwise similarities.
