Transcribe Breton audio with WhisperAI
WhisperAI transcribes Breton (Brezhoneg) audio for the around 200,000 speakers, with active revitalisation in Brittany who use the language across Brittany (Bretagne) in northwestern France. Built on OpenAI Whisper and tuned for the realities of Breton speech, the service produces publication-grade transcripts in Latin alphabet with c'h (a digraph for the back fricative).
Who actually needs Breton transcription
Breton demand comes from Breton-revitalisation media (especially Diwan schools and France Bleu Breizh Izel), cultural institutions, and Breton-language broadcasting.
Dialects and varieties handled
- Kerneveg (Cornouaille)
- Leoneg (Léon)
- Tregerieg (Trégor)
- Gwenedeg (Vannes)
Breton as a Celtic language with no help from French ASR
Breton is a Celtic language (related to Welsh and Cornish), not a Romance language — so ASR trained on French handles it badly despite Brittany being part of France. Whisper handles Breton on its own terms with the standard Peurunvan orthography and the c'h digraph preserved.
Kerneveg, Leoneg, Tregerieg and Gwenedeg dialects are all supported.
