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
Speechmatics
Speechmatics is a speech-to-text API covering 55+ languages with speaker diarization, custom vocabulary and mid-sentence code-switching. It runs on-device, on-premises or in the cloud, and posted the lowest word error rate in an independent 12-service benchmark in August 2026.
- An independently benchmarked accuracy result, which almost nothing else in this category has
- Code-switching handles how a large share of the world actually speaks
- On-device deployment removes the compliance problem rather than managing it
- Certification set clears healthcare and legal procurement without a special case
- Infrastructure, not an application — no summaries, notes or search out of the box
- A pooled benchmark says little about performance on your specific domain audio
- Word error rate weights a missed article the same as a missed drug name
