A single, unified Voice Agent API

Instead of stitching together separate components, Deepgram unifies speech-to-text, text-to-speech, and LLM orchestration into a single API, reducing complexity, latency, and cost.

Your customer or end user speaking naturally.

Partner-provided transport layer that bridges stream audio into Deepgram's APIs and plays back TTS audio to the end user, including Telephony partners (via PSTN/SIP)

Conversational speech recognition that detects end-of-turn and interruptions, and streams transcripts in real-time.

Coordinates context, memory, and AI reasoning.

  • Context: Maintains conversation history and system settings.

  • System Updates: Adjusts role or behavior.

  • Prompt Updates: Refines instructions in real time.

  • Response Injections: Adds guidance or context.

  • Function Calling: Executes actions or fetches data.

  • LLM (via API): Connects to language models for response generation.

Converts AI responses into natural-sounding speech.

Your custom application logic. Executes domain-specific actions, integrates external APIs, or adds validation before results flow back into the agent.

Databases, APIs, and back-office systems that the agent interacts with. Results are fed back into the conversation context for grounding.
