Callers genuinely cannot tell at first — and they get what they called for without waiting on hold.
Operations Manager
We built a real-time AI voice agent that answers calls, understands natural speech, and completes tasks — booking appointments, answering questions, and routing complex calls — with low-latency, human-like conversation.
| Project Detail | Information |

| Project Type | Web & Telephony |
| Industry | Telephony |
| Technologies | Streaming STT, LLM, Neural TTS, Twilio, WebRTC, Node.js |
| Delivery Partner | mTouch Labs |
| Primary Outcome | The voice agent absorbed routine call volume around the clock while keeping callers satisfied. |
The client's phone lines were overwhelmed, callers abandoned long IVR menus, and after-hours calls went unanswered, costing bookings and goodwill.
We assembled a low-latency pipeline of streaming speech-to-text, an LLM for reasoning, and natural text-to-speech, with barge-in support so callers can interrupt naturally.
The voice agent handles calls 24/7, completes bookings and FAQs autonomously, and warm-transfers to staff with context when a human is needed.

It is a system that answers phone calls, understands natural speech in real time, holds a conversation, and completes tasks such as bookings or lookups, transferring to a human when needed.
We engineer the speech-to-text, reasoning, and text-to-speech pipeline for low latency and support barge-in, so callers can interrupt and speak naturally.
