Overview

What it is and why it exists

A practical look at the problem, the approach, and what makes this product different from a generic implementation.

Problem

Most voice assistants either feel laggy and robotic or hallucinate confidently. Teams building voice-first features need a real-time conversational layer that listens, thinks, and speaks back fast enough to feel natural — without sacrificing factual grounding.

Solution

A streaming voice-to-voice bot that captures audio, transcribes it live, reasons with an LLM, and speaks back with low-latency TTS. Conversations stay coherent across turns, and every interaction is logged with audio + transcript for review.

What makes it different

Tuned for sub-second turn-taking on real-world audio, not studio-clean clips. Interruption-aware: the bot stops talking when the user starts. Built so the same brain can power phone calls, web widgets, kiosks or mobile.
