Speak4Me is a text to speech app that does two things: it reads aloud anything you want to listen to, and it speaks out loud anything you type. Listen to PDFs, documents, books, web articles and photos of printed pages – or type a message and let Speak4Me say it for you, in 120+ natural AI voices. LISTEN: READ ALOUD ANYTHING • PDF to audio – Import any PDF from Files or iCloud Drive and listen to it like an audiobook. Headers and footers are skipped automatically, so you only hear the content. • Documents and books – Turn long documents, book chapters, study notes and reports into audio. Follow along with real-time text highlighting. • Web articles – Listen to articles, blog posts and newsletters instead of reading them on screen. • Scan and listen – Take a photo of a printed page, a book, a letter or a menu, and Speak4Me reads the text out loud. • Listen anywhere – Keep listening while you commute, walk, work out or cook. Speed up the voice to get through your reading list faster. SPEAK: TYPE TO SPEAK • Type and Speak4Me talks for you – Write what you want to say and it is spoken out loud instantly, in the voice and language you choose. • A voice when you need one – Made for people who have lost their voice, have a speech disability, are recovering from a stroke, or find it hard to speak in some moments. Use it to talk face to face, at the doctor, in a shop or on the phone. • Favorite phrases – Save the sentences you use most and play them with one tap. • AI voice-overs – Use Speak4Me as an AI voice generator and narrator: type a script and export it as an MP3 for videos, TikTok, Reels, podcasts, presentations and customer support. NATURAL AI VOICES • 120+ lifelike AI voices, male and female, in 20+ languages and accents. • Ultra voices: our most human, expressive and fluid voices. • Adjust voice speed and font size to fit the way you read. MADE FOR EVERY READER • Dyslexia-friendly font and text highlighting to make reading easier. • Helpful for dyslexia, ADHD, low vision, language learners and anyone who prefers listening to reading. • Save any audio and share it via iMessage, WhatsApp, email and more.
