wasertech/TrainingSpeech

TrainingSpeech is an initiative to provide open and freely reusable dataset of voices

• for speech-to-text models training

• on non-english languages

• using already available data (such as audio-books).

Right now, data are extracted exclusively from audio-books and in French language. Let me know if you are intersted to contribute by creating an issue.

Tooling

TrainingSpeech comes with a CLI that automate and simplify:

• transcript extraction
• forced-alignment (using aeneas)
• validation and correction

Common workflow

1. Generate and validate alignment on existing source

1. pick a source that have NOT been validated yet: see python manage.py stats and ./sources.json for more info
2. download assets (ie epub and mp3 files): python manage.py download -s <SOURCE_NAME>
3. check alignment: python manage.py check-alignment <SOURCE_NAME> (may require multiple iterations)
4. send a pull request with generated transcript and alignment

2. Add New source (team members only)

1. retrieve epub and corresponding mp3 file and store them into ./data/epubs and ./data/mp3 (respectively)
2. create new source into ./sources.json (NB: all fields are mandatory)
3. generate initial transcript using python manage.py build-transcript <SOURCE_NAME>
4. upload epub and mp3 files on S3 python manage.py upload -s <SOURCE_NAME>
