Built for Production

We handle the complex orchestration of turning voice into data and back again, so you can focus on the conversation logic.

Low Latency

Optimized edge infrastructure ensures voice-to-voice response times under 800ms. Feels like a real human conversation.

Interruption Handling

Our endpoint detection automatically handles interruptions. If the user speaks over the AI, the AI stops talking instantly.

Function Calling

Empower your voice assistant to take action. Book appointments, query databases, or trigger workflows via API.

Bring Your Own Models

VoxStack is agnostic. We provide the plumbing; you choose the providers. Switch between models with one line of code.
