Speech-to-text

Gladia

French speech-to-text API (Solaria models) with async and real-time transcription, diarization included, and EU hosting by default.

A natural pick for European buyers who want a French-run vendor, with EU-west processing by default and US-west selectable per request. Pay-as-you-go Starter costs $0.61/hour async and $0.75/hour real-time from a prepaid wallet, high for the category, but a Growth commitment can bring that down to $0.20/hour and $0.25/hour. Diarization, language detection and code switching are included rather than billed as add-ons, though self-serve files are capped at 135 minutes.
