ChannelAugment: Improving generalization of multi-channel ASR by training with input channel randomization
Marco Gaudesi, Felix Weninger, Dushyant Sharma +1
End-to-end (E2E) multi-channel ASR systems show state-of-the-art performance in far-field ASR tasks by joint training of a multi-channel front-end along with the ASR model. The mai…

Self-Attention Channel Combinator Frontend for End-to-End Multichannel Far-field Speech Recognition
Rong Gong, Carl Quillen, Dushyant Sharma +3
When a sufficiently large far-field training data is presented, jointly optimizing a multichannel frontend and an end-to-end (E2E) Automatic Speech Recognition (ASR) backend shows…
