Dream TTS reads your books, PDFs and articles aloud in a natural voice, and the page follows it word by word. Private by design: nothing you read leaves your device. A NATURAL VOICE Choose from 28 voices in American and British English, and set the pace that suits you. Each word is lit as it is spoken, so you can look away and find your place again at a glance. It keeps reading with your iPhone locked: pause and skip from the Lock Screen or your headphones.
