Voice Agent API features
Powered by the industry’s fastest, most performant speech recognition and voice synthesis models, our voice agent stack delivers unparalleled performance and scale.
Unified Voice Agent API
One API that combines speech-to-text, LLM orchestration, and text-to-speech in real time. Simplifies development by eliminating the need to stitch together multiple services.
Conversational control
Built-in barge-in detection, turn-taking prediction, function calling, and mid-session control ensure smooth conversations without pauses or interruptions.
Full model ownership
Deepgram controls the full voice stack across STT, TTS, and runtime orchestration for optimized latency, model tuning, and tightly synchronized speech-to-speech flow.
Deployment flexibility
Deploy fully managed, dedicated single-tenant, in VPC, or self-hosted. Supports HIPAA, GDPR, regional data residency, and isolated runtimes for enterprise compliance.
BYO LLM & TTS
Easily integrate your own LLM or TTS provider while retaining Deepgram’s orchestration, streaming pipeline, and real-time responsiveness.
Scalable cost optimization
Flat-rate pricing at $4.50/hr with Deepgram’s full stack, plus built-in rate reductions for BYOM. Optimized compute efficiency lowers TCO for large-scale deployments.
Powering the future of real-time Voice AI Agents
Our Voice Agent API enables real-time conversational AI agents that seamlessly handle interruptions, take complex actions, and deliver natural, responsive customer interactions without delays or rigid turn-taking.
