The platform

Built for production.
Not a prototype.

Every layer of the Voxa stack is designed for real-time voice at scale — not adapted from a batch-processing background.

The complete stack.

One platform. Every piece you need to build, deploy, and observe voice AI in production.

Realtime Voice Pipeline

LiveKit WebRTC streaming with sub-300ms voice-to-voice latency. ASR, LLM, and TTS run in parallel — interruptions and barge-in handled natively.

Model Agnostic

Swap GPT-4o, Claude, Gemini, Llama, or your own fine-tune in one line. Bring-your-own-key on every tier — your usage doesn't count against Voxa minutes.

Function Calling That Works

Hit any HTTP endpoint mid-conversation. Type-safe schemas, automatic retries, structured arguments — no prompt-engineering gymnastics required.

Compliance & Data Residency

HIPAA, SOC 2 Type II, GDPR, and PCI workflows ship as policies. Pin data residency to EU or US; audit every transcript with cryptographic provenance.
