Deepgram
Deepgram provides speech-to-text and text-to-speech through its Flux models, plus a Voice Agent API that combines transcription, speech synthesis and LLM orchestration into a single interface. Everything runs in real time or batch, in the cloud or self-hosted, with text-to-speech latency stated as low as 80ms.
- Built for real-time agents rather than transcription with agents added afterwards
- One API removes latency hops that make automated voice feel broken
- 80ms synthesis latency is genuinely competitive for conversational use
- Self-hosting offered as a normal option rather than an enterprise negotiation
- No language count or list published on the pages a buyer reads first
- No accuracy or word error rate figures anywhere on those pages
- No compliance certifications stated, despite targeting regulated buyers with self-hosting
Rev
Rev has repositioned from transcription into an investigative intelligence platform for legal teams, combining AI evidence analysis with human-verified transcription guaranteed 99%+ accurate in 12 hours, plus court reporting, deposition summaries and a speech-to-text API.
- A guaranteed accuracy figure, which no pure-AI service offers
- Page:line accuracy on deposition summaries is the detail legal work actually turns on
- Two legal transcript tiers match the working copy and the filed copy
- Evidence analysis works across a set of files rather than one at a time
- Human captions cover only English and Spanish
- Subtitle coverage of 17 languages trails API-first vendors offering 50+
- Substantially more expensive than AI transcription for work that does not need a guarantee
