Bekwarra + English speech service
# Dialingua voice
Bekwarra and English speech as downloadable WAV, on Render's free tier.
Serves `facebook/mms-tts-bkv` — Meta's real Bekwarra voice model — instead of
the browser's English `speechSynthesis`, which applies English phonetics to
Bekwarra spelling and cannot be saved to a file.
Models are **not** quantised. int8 would save ~80 MB and audibly degrade a
vocoder; the point of this service is that it should sound like Bekwarra.
`GET /health` · `POST /tts {"text": "...", "lang": "bkv"|"eng"}` → audio/wav
