The Voice Travel Agent is a real-time conversational system designed to behave like a live phone-based assistant rather than a turn-based voice demo. The system listens continuously, streams speech-to-text, generates responses incrementally, and speaks back to the user with near-immediate playback.
A key focus of the project was handling the practical engineering challenges of voice-first interaction, including low-latency pipelines, concurrent audio input and output, and interruption-safe playback. The agent supports natural barge-in, allowing users to interrupt responses at any point without breaking conversational flow.
This project demonstrates hands-on experience with building streaming, real-time voice agents that feel responsive and usable in real conditions, rather than scripted or sequential.
The full write-up covers the streaming speech pipeline, concurrency model, interruption handling, and voice-specific UX constraints.
