## Which one, for what

### ElevenLabs Scribe Speech to Text API (B)

Good for: Batch transcription where diarisation, entity detection and keyterms matter, and for teams already on ElevenLabs for speech.

Ahead on:
- Schema & documentation, 95 against 58
- Maintenance & community, 75 against 68

Also in its favour:
- Runs on your own machine

Watch for: Audio may be used for training unless the account opts out, and the opt-out isn't retroactive

### Groq Speech-to-Text (BB)

Good for: Suited to cheap, fast transcription of recorded files in many languages, and to agents that already hold a Groq key or use an OpenAI-compatible client.

Ahead on:
- Reliability, 90 against 70
- Security & auth, 79 against 55
- Transparency & trust, 85 against 70

Also in its favour:
- Agent-ready, a grade of BB or better
- Free to start without a card

Watch for: No streaming or realtime endpoint and no diarisation in the reviewed documentation

## Verdicts

**ElevenLabs Scribe Speech to Text API.** $0.22 an hour for batch with 90+ languages and diarisation to 32 speakers. Audio may be used for training unless the account opts out, and the opt-out isn't retroactive.

**Groq Speech-to-Text.** Whisper Large v3 Turbo costs $0.04 an audio hour and Whisper Large v3 $0.111, with a no-card free plan and zero data retention as a self-serve setting. There is no streaming endpoint, no diarisation and no subtitle output, and uploads stop at 25 MB on the free plan and 100 MB on the Developer plan.

## Before you call either

### ElevenLabs Scribe Speech to Text API

1. Create a key restricted to speech-to-text with a credit quota and an expiry
2. Use `source_url` for hosted files instead of downloading and re-uploading
3. Set `webhook=true` for long files so the call doesn't block
4. Back off exponentially on any of the three 429 codes
5. Opt out under Data use before sending customer audio. It only covers later uploads

### Groq Speech-to-Text

1. Send `whisper-large-v3-turbo` for transcription and `whisper-large-v3` for translation to English. The translations endpoint does not accept Turbo.
2. Pass `url` instead of `file` for audio over 25 MB, and split anything over the plan's size limit into overlapping chunks before sending.
3. Set `response_format` to `verbose_json` before asking for `timestamp_granularities[]`. Word timestamps add latency, segment timestamps do not.
4. Every request is billed as at least 10 seconds of audio, so join very short clips where the task allows.
5. Read `retry-after` on a 429 and back off. Audio limits count seconds an hour and a day as well as requests.
