Improving Contextual Spelling Correction by External Acoustics Attention and Semantic Aware Data Augmentation

no code implementations22 Feb 2023 Xiaoqiang Wang, Yanqing Liu, Jinyu Li, Sheng Zhao

To solve above limitations, in this paper we propose an improved non-autoregressive (NAR) spelling correction model for contextual biasing in E2E neural transducer-based ASR systems to improve the previous CSC model from two perspectives: Firstly, we incorporate acoustics information with an external attention as well as text hypotheses into CSC to better distinguish target phrase from dissimilar or irrelevant phrases.

RetrieverTTS: Modeling Decomposed Factors for Text-Based Speech Insertion

no code implementations28 Jun 2022 Dacheng Yin, Chuanxin Tang, Yanqing Liu, Xiaoqiang Wang, Zhiyuan Zhao, Yucheng Zhao, Zhiwei Xiong, Sheng Zhao, Chong Luo

In the proposed paradigm, global and local factors in speech are explicitly decomposed and separately manipulated to achieve high speaker similarity and continuous prosody.

QRelScore: Better Evaluating Generated Questions with Deeper Understanding of Context-aware Relevance

no code implementations29 Apr 2022 Xiaoqiang Wang, Bang Liu, Siliang Tang, Lingfei Wu

Existing metrics for assessing question generation not only require costly human reference but also fail to take into account the input context of generation, rendering the lack of deep understanding of the relevance between the generated questions and input contexts.

Quantum tensor singular value decomposition with applications to recommendation systems

no code implementations3 Oct 2019 Xiaoqiang Wang, Lejia Gu, Joseph Heung-wing Joseph Lee, Guofeng Zhang

In this paper, we present a quantum singular value decomposition algorithm for third-order tensors inspired by the classical algorithm of tensor singular value decomposition (t-svd) and then extend it to order-$p$ tensors.
