Deepgram
Deepgram
Best for: API & Platform for people who want a checked, free option.
Deepgram sells developer-grade speech APIs: streaming and pre-recorded transcription (Nova-3), text-to-speech, audio-intelligence features, and a Voice Agent API for building real-time voice assistants.
New accounts get $200 in free credit — roughly 43,000 minutes of Nova-3 transcription — that never expires, with no credit card required to start. Beyond that it is pay-as-you-go: Nova-3 streaming at $0.0077/minute, pre-recorded at $0.0043/minute; Growth agreements start at $4,000/year for committed discounts.
It fits developers adding transcription or voice to an app, and teams evaluating speech quality against AssemblyAI and Whisper — the free credit is large enough for a real evaluation, not a toy demo.
To begin, sign up at deepgram.com/console and use the API key immediately; EU endpoints and self-hosted containers (Enterprise) exist.
The honest limits. It is an API, not an app — you write the integration. Credit covers usage only; the self-hosted path requires Enterprise terms. Not used first-hand; confirm at deepgram.com/pricing.
