Deepgram provides APIs for turning speech into text, text into speech, and building complete voice agents. Its Flux models are designed for live conversation, handling turn-taking, interruptions and context so agents sound more natural.

Services run in real time or in batch, either in the cloud or self-hosted, making it suitable for larger companies with strict needs. A free starting option and a browser playground let developers test the tools before paying.
