Spokio: Offline Text to Speech

Spokio turns text and documents into natural speech directly on your iPhone.

Generate voiceovers, narration, spoken drafts, course audio, and reusable audio without sending your synthesis text or voice samples to Spokio servers. Choose a built-in voice or create a custom voice from a short recording or an audio file you have permission to use.

MAC + IPHONE
Spokio is available on Mac and iPhone as one product with Universal Purchase. An eligible Spokio Pro purchase can unlock supported Pro features on both platforms when you use the same Apple Account. The Mac and iPhone apps are designed for their platforms, so some workflows and pro features differ.

REQUIREMENTS
• iOS 26 or later
• iPhone
• English text synthesis

Generation speed depends on your device and the length of the text. Spokio is designed for generation-first workflows rather than live conversation or realtime speech.
