What is Deepgram?
Deepgram is an enterprise-grade voice AI platform offering high-accuracy Speech-to-Text (STT), Text-to-Speech (TTS), and Voice Agent APIs.Built specifically for real-time interaction, its infrastructure supports massive scale, ensuring voice applications feel as natural and responsive as human conversation.
The platform introduces Flux TTS, a 'conversation-native' text-to-speech model designed for real-time voice agents.By eliminating the latency bottlenecks of traditional pipelines and housing both STT and TTS under one enterprise runtime, Deepgram removes integration gaps and delivers superior performance for multi-turn dialogues.
Trusted by over 5,000 organizations and built by more than 650,000 developers, Deepgram has processed over 200,000 years of audio.From contact center solutions to real-time transcription and interactive voice assistants, it provides a complete toolkit—including docs and a Playground—to help teams ship voice experiences quickly.
