Voicebox underwent intensive coaching utilizing a dataset comprising over 50,000 hours of unfiltered audio. The AI mannequin was educated utilizing Meta’s progressive “Move Matching” method, a flexible different to diffusion-based studying strategies employed by different generative fashions.
Meta’s coaching dataset contains recorded speech and transcripts from public-domain audiobooks in a number of languages, equivalent to English, French, Spanish, German, Polish, and Portuguese.
