Reading aloud is free, with no time limit. Premium, an in-app purchase, adds 28 on-device Studio Voices — try it free for 7 days.
Mi Speaks reads your books, articles and documents aloud in voices that sound genuinely human — generated on your device, never in the cloud.
STUDIO VOICES
Twenty-eight neural voices, American and British, male and female. They run entirely on your iPhone: nothing you read is ever uploaded, and they work in airplane mode. Blend two voices together to make one of your own.
READ ALONG
Every word is highlighted as it is spoken. Import a PDF and you can follow along on the real page, with the word lit where it actually sits — not a transcription of your book, but your book.
FIND YOUR PLACE
Jump straight to any chapter of an imported PDF. Mi Speaks remembers where you stopped, on every device. Skip from chapter to chapter right from the lock screen.
BEFORE YOU PUT THE PHONE DOWN
Studio Voices need no connection once they are installed, but generating them uses the graphics processor, and iOS will not run that while an app is off screen. Prepare Full Document renders every sentence up front — after that there is nothing left to generate, so it plays to the end with the screen locked, in another app, or on a flight. And if you haven't prepared a document, reading still doesn't stop: any passage that isn't ready yet is read in your own system voice, and Mi Speaks offers to prepare the rest for next time.

The app sounds ok but if you follow the instructions and download “Premium” and “Enhanced” voices in your phones settings under accessibility it sounds a lot better using those voices. I like that I can send anything to it and the latest update that syncs across devices is wonderful. The animations are a little jumpy but for the price cannot complain much.
Studio Voices now download once and stay. Until now the voice model came down again after every app update — all 325 MB of it, even when nothing in it had changed. It is hosted by Apple now and kept on the iPhone from one update to the next, and the download shows its real progress as it goes.
