Live playback customization

Change voice, language, and speed during listening without restarting.

Speechdash applies playback changes immediately while audio is playing. You do not need to stop and restart the document.

Voice roles during playback

Documents with dialogue-style versions may assign different roles (Narrator, Questioner, Expert) to passages. Role-to-voice mapping comes from your defaults in Settings → General, but you can override the active voice anytime from the playback bar.

Defaults vs saved changes

ScopeApplies to
Settings → GeneralDefault voices and speed for new imports and new versions
Playback barThe active document version (saved when you change voice, speed, Eco/Cloud, or listening language)

Changing speed or voice on the bar updates this document's saved playback settings. It does not change your account defaults in Settings unless you edit those separately.

Eco mode note

In Eco mode, voice synthesis runs locally in your browser. All ten presets and speed changes work offline after the page loads. Cloud mode streams higher-quality audio and deducts credits per sentence.
