How to prepare train-2-mix?

[MisakiWho]

Training requires train-2mix.jsonl, but LibrispeechMix dataset doesn't contain list/train-2-mix.json

Hello, unfortunately LibriSpeechMix provides only dev/test manifest files, but no training. You would have to write your own utterance mixing script to generate manifest files with the same structure (using utterances from LibriSpeech train set, for example).
