An Investigation of Using Hybrid Modeling Units for Improving End-to-End Speech Recognition System

Shunfei Chen, Xinhui Hu, Sheng Li, Xinkang Xu

ICASSP 2021accepted

The acoustic modeling unit is crucial for an end-to-end speech recognition system, especially for the Mandarin language. Until now, most of the studies on Mandarin speech recognition focused on individual units, and few of them paid attention to using a combination of these units. This paper uses a…
