Descrizione

Note: this is issue is part of MLH fellowship

We would like to have more speech data augmentation in Fairseq.

I've been using augly which uses a lot of torchaudio.sox_effects, but I haven't been quite happy with the performance. All the sox_effects happen on CPU, which can be slow. I think some of them would better be implemented on GPU.

torchaudio tutorial explain how to implement some data augmentation, and their samples would work on GPU.

I'm interested in reverb, change_volume, add_background_noise, tempo and pitch_shift.
