Best / Transcription

Best open-source Transcription

The best self-hosted transcription split in the c17.io catalog is whisper.cpp for an MIT local Whisper port (the published Descript / Riverside / Gong / Rev / Notta stack — not the OpenAI Whisper API), Vosk when you want that Apache-2.0 offline API, faster-whisper when you want that MIT CTranslate2 port, and meetily when the job is meeting minutes rather than a file transcript. Piper stays TTS (/replace/elevenlabs). This is not Rev's every human-caption SKU, Notta's every AI summary SKU, or Gong's deal board.

FAQ

whisper.cpp or Vosk?
whisper.cpp if you want the published Rev / Descript path. Vosk if you want that Apache offline API — /compare/whisper-vs-vosk.
Rev or Notta?
Same published transcript — /replace/rev-com and /replace/notta. Otter minutes stay on /best/transcription.
Is this Otter?
Minutes on a live room stay on /best/transcription (meetily). This page is speech-to-text you run.
Are these free?
whisper.cpp and faster-whisper are MIT. Vosk is Apache-2.0. You pay hosting and any GPU. Template users never pay c17.
How do I deploy it?
Open /stacks/whisper-transcribe. Persist the model. Transcribe one file you actually have.
