Inside Murmura: Building Real-Time Voice

Inside Murmura: Building Real-Time Voice

A look at how we cut generation latency to a fraction of a second so voices can respond in live conversations.

Daniel Reyes

Why latency matters

In a live conversation, every extra half second feels like hesitation. To make AI voices work in calls and assistants, audio needs to start playing almost instantly.

Streaming from the first word

Instead of waiting for a full sentence, Murmura streams audio as soon as the first words are ready. Listeners hear speech while the rest is still being generated.

Keeping quality high

Faster output can sound choppy if the model loses context. We keep a short look-ahead window so intonation stays natural across sentence boundaries.

The result is a voice that responds in a fraction of a second while still sounding calm and consistent.
