TTS Composer

Compose & preview multi-voice scripts.

Write or paste a script, split it into segments by paragraph, by sentence or by hand, and assign voices per line with a [Speaker]: prefix. Preview segments with your browser's speech voices — a local voice by default; an online voice you select may send text to the browser's speech service. Export the plan as JSON or plain text; no audio file is produced.

Previews use browser speech voices. Local voices process on your device; choosing an online voice may send your text to the browser’s speech service.
