Voice AI Agent Development
Voice agents that handle interruption like a human would — barge-in, backchannel audio, and one agent core across every channel.
Most voice AI demos work in a quiet room with one polite caller. The moment a real user interrupts mid-sentence, asks a follow-up before the agent finishes talking, or moves from a chat thread to an actual phone call, the illusion breaks — the agent talks over them, stalls mid-answer while retrieval runs, or starts over as if the conversation never happened.
We build AI-assisted, voice-enabled knowledge assistants and retrieval systems. Streaming STT and TTS run with real barge-in: the moment a caller speaks, in-flight speech and generation cancel against a ~100ms target, instead of finishing the current sentence first. On turns that need retrieval, backchannel audio masks the gap so the agent sounds like it's listening rather than stalling. And it's the same agent regardless of channel — one core carries the retrieval, persona, guardrails, and memory across text, voice-note, and live-call transports; only the transport and turn-taking logic change underneath it.
Transport is a swappable seam, not a foundation poured in concrete: we start on WebSocket, which needs no media server, and WebRTC is a bounded swap when browser-based calling is needed later — a transport change, not a rewrite of the agent underneath it. Cost is architected in from the start, not bolted on after a spend spike — per-tenant concurrent-call caps, a hard spend cap, a kill switch, and session timeouts, the same discipline we apply to every other engineering guarantee.
What you get
What we deliver
- Working voice agent deployed to your infrastructure
- Cost controls configured — concurrency caps, spend cap, kill switch, session timeouts
- Numbered ADRs recording every architectural decision and deviation
- Security review across every surface before handover
- Runbook and 30-day warranty
Who it's for
- Founders who need a voice agent that survives a real caller interrupting it, not a chatbot with text-to-speech bolted on
- Teams with an existing text agent who need the same retrieval, guardrails, and memory on a live phone call
- Companies whose voice pilot broke on interruption handling or ran up cost nobody had capped
