Expressive speech from a concise script
How to generate AI speech on iPhone.
AI Text to Speech is an online ClipFlow Pro service, distinct from the longer-form Apple System TTS tool.
Choose voice and direction
Select one of eight Chinese and English male or female voices, then optionally start the text with a parenthetical style tag.
Generate and continue
Send the request to the ClipFlow TTS service, receive a WAV file, then save, trim, speed-adjust, or add it to video.
What style tags can change
A parenthetical tag at the beginning can ask for an emotion, conversational tone, dialect, or singing style. The tag guides generation rather than acting as a guaranteed command, so short experiments may be useful before a final take.
Generation requires an internet connection and ClipFlow Pro. The request sends the input text, selected voice, a device UUID, and subscription transaction identifier to ClipFlow's TTS service for generation and entitlement verification. The generated WAV is returned to the app for local next steps.
