DeepgramUnclaimed

Deepgram is a voice AI platform for developers. It offers APIs for speech-to-text (STT), text-to-speech (TTS) and voice agents, which listen to a caller, work out a reply and speak it back. The page describes the platform as available as a managed API with US, EU and Australia endpoints, and also in-VPC or self-hosted.

The speech-to-text models include Flux STT and Nova-3, offered in English and multilingual versions for streaming and pre-recorded audio. Add-ons cover features such as redaction, speaker diarization, entity detection and keyterm prompting, and smart formatting is included at no cost. The text-to-speech product, Flux TTS, is billed per 1,000 characters, and the Voice Agent API is billed per minute of WebSocket connection time.

The page points to use cases including contact centers, restaurants, pharma, medical and government, along with transcription, conversational AI and speech analytics. Its example projects include comparing TTS voices side by side, adding spoken replies to an existing chatbot, streaming LLM output into speech, and building a receptionist that books appointments through function calling.

For compliance, the pricing page says the company is SOC 2 Type 1 and Type 2 certified, signs Business Associate Agreements for Enterprise customers handling electronic protected health information, and offers a dedicated EU endpoint for GDPR data residency.
