Rohan Doshi, Youzheng Chen, Liyang Jiang, Xia Zhang, Fadi Biadsy, Bhuvana Ramabhadran +3

ICASSP 2021accepted

We present an extended Parrotron model: a single, end-to-end network that enables voice conversion and recognition simultaneously. Input spectrograms are transformed to output spectrograms in the voice of a predetermined target speaker while also generating hypotheses in a target vocabulary. We stud…

Specaugment on Large Scale Datasets

Daniel S. Park, Yu Zhang, Chung-Cheng Chiu, Youzheng Chen, Bo Li, William Chan +2

ICASSP 2020accepted

Recently, SpecAugment, an augmentation scheme for automatic speech recognition that acts directly on the spectrogram of input utterances, has shown to be highly effective in enhancing the performance of end-to-end networks on public datasets. In this paper, we demonstrate its effectiveness on tasks…
