Streaming TTS Guide

Streaming returns audio chunks as they are generated, so playback can start before the whole clip is ready. Use it for long text and any experience where a wait before speech would feel broken.

Speech vs stream

When to stream

Reach for streaming when the first-byte wait matters: read-aloud features, in-app playback of long articles, or any interface where the user presses play and expects immediate sound. For a short, fixed clip you render once and cache, the speech endpoint is simpler.
