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 — PREMIUM 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. FREE, WITH NO TIME LIMIT + Read documents of any length + Import text, PDFs, photos of pages, and anything from the share sheet + Live word highlighting, background playback, lock screen controls + PDF page view and chapter navigation + Keep 3 documents in your library, each remembering where you left off + Resume Reading widget on the home and lock screen + Works completely offline PREMIUM ADDS — IN-APP PURCHASE * Studio Voices — all 28, on device * An unlimited library, in sync across iPhone, iPad and Apple Watch * Every playback speed from 0.5x to 2x, plus Turbo * Export anything to an audio file you can keep Premium is an optional in-app purchase: a 7-day free trial, then a Monthly or Yearly auto-renewing subscription. There is also a one-time Lifetime purchase if you would rather not subscribe. Studio Voices need a one-time download of about 325 MB.
