About

Simple Voice Reader

Features
Read full description

Simple Voice Reader is a free text-to-speech app for iPhone and iPad that reads pasted or typed text, TXT files, RTF files, and PDFs aloud. Open supported documents from Files, use the import button, or drag text and files directly into the reader on iPad. American English Apple system voices work immediately. For the best Apple voice quality, download Apple's free Enhanced and Premium voices in Settings > Accessibility > Spoken Content > Voices > English. On compatible iOS 26 devices, you can also download an optional American English Kokoro voice pack with Heart and 19 other natural voices. The pack is about 170 MB, downloads once from Apple, and can be removed at any time. Use Simple Voice Reader when you want to listen instead of read: long articles, notes, drafts, manuals, study material, book chapters, accessibility material, or anything else you can paste or import. Choose a voice, adjust speed, change the reading font and size, start from the cursor, pause and resume, and follow the highlighted words as the reader moves through the text. Apple speech continues when the app moves to the background or the screen locks, with pause, resume, and stop controls on the Lock Screen and in Control Center. If Kokoro cannot continue because the device needs more memory or the app moves to the background, reading continues with the selected Apple voice. Privacy: text-to-speech conversion with Apple and Kokoro voices is performed on the user's device. Simple Voice Reader does not send text, documents, or spoken audio to Walter Claw Software or to a cloud text-to-speech service. iOS may contact Apple only to download system voice assets and the optional Apple-hosted Kokoro voice pack selected by the user. Simple Voice Reader is free. No account, purchase, or subscription is required.
