Deepgram

Deepgram is a voice AI platform for developers. Its speech-to-text API transcribes audio in real time or in batches with high accuracy and low latency, using Deepgram's own Nova models, and it supports many languages.

Beyond transcription, Deepgram offers Aura text-to-speech voices and a Voice Agent API for building conversational voice bots that listen, think and speak. Features such as speaker diarisation, smart formatting, keyword boosting and summarisation make it popular for call centres, meeting tools, voice assistants and media transcription.

Good fit if you: are building a product that needs fast, accurate speech recognition or voice agents through an API.
Less ideal if you: just want to transcribe a few files without coding; an end-user transcription app will be simpler.

Pricing: pay-as-you-go based on usage, with free starting credit for new accounts; enterprise plans are available.
