Key features

Sub-second latency

Streaming speech-to-text and TTS for natural turn-taking.

Barge-in handling

Callers can interrupt naturally, like a real conversation.

Tool calling

Agents act on live systems — bookings, lookups, updates.

Warm handoff

Seamless escalation to human agents with full context.

Multilingual

Real-time support across multiple languages.

Call analytics

Transcripts, sentiment, and outcome tracking per call.

Challenge

Traditional IVR and chatbot voice systems feel robotic and frustrate callers with rigid menus and high latency.

Solution

We orchestrated streaming STT, LLM reasoning, and TTS over LiveKit's real-time infrastructure to deliver genuinely conversational voice agents.

Outcome

Callers resolve more issues without a human, and containment rates rose sharply while satisfaction held steady.
