### **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](/content/pricing/index.html) 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.
