Mask scalar prediction for improving robust automatic speech recognition

no code implementations26 Apr 2022 Arun Narayanan, James Walker, Sankaran Panchapagesan, Nathan Howard, Yuma Koizumi

Using neural network based acoustic frontends for improving robustness of streaming automatic speech recognition (ASR) systems is challenging because of the causality constraints and the resulting distortion that the frontend processing introduces in speech.

A Conformer-based ASR Frontend for Joint Acoustic Echo Cancellation, Speech Enhancement and Speech Separation

no code implementations18 Nov 2021 Tom O'Malley, Arun Narayanan, Quan Wang, Alex Park, James Walker, Nathan Howard

Compared to the noisy baseline, the joint model reduces the word error rate in low signal-to-noise ratio conditions by at least 71% on our echo cancellation dataset, 10% on our noisy dataset, and 26% on our multi-speaker dataset.
