Improving Speech Representation Learning via Speech-level and Phoneme-level Masking Approach

no code implementations • 25 Oct 2022 • xulong Zhang, Jianzong Wang, Ning Cheng, Kexin Zhu, Jing Xiao

In this work, we proposed two kinds of masking approaches: (1) speech-level masking, making the model to mask more speech segments than silence segments, (2) phoneme-level masking, forcing the model to mask the whole frames of the phoneme, instead of phoneme pieces.
