# Streaming

> Low-latency streaming text to speech.

Breeze supports both `POST /v1/text-to-speech/{voice_id}` for non-streaming output and `POST /v1/text-to-speech/{voice_id}/stream` for streaming output.

Use the streaming endpoint for lower time-to-first-byte and chunked audio. Streaming supports `mp3` and `pcm` output formats.

Timing metadata and realtime text input over WebSocket are planned.
