Re: [Kaldi-users] LibriSpeech nnet2 model: training more on a new dataset

[Jonathan L <jon...@gm...>]

The data I want to train on is in MP3 format at a 128kbps bitrate and a
44.1kHz sample rate. The LibriSpeech data has a 16kHz sample rate, but
doesn't seem to have a specified bitrate, When I convert the MP3 files into
16kHz sample-rate WAV files, what bitrate should I convert them to?

Is there anything else I should consider when converting the speech files?
