Turn Reading Time into Listening Time

OpenVox Reader transforms books, PDFs, documents, web links and text into natural-sounding audio, so you can keep reading while commuting, walking, exercising, relaxing or working.

Import your content, choose from hundreds of voices, create your own custom voice, and listen at your preferred speed without sending your private documents to an online text-to-speech service.

Listen to Almost Anything

Bring all your reading into one simple library:

• Import ebooks and PDFs
• Add documents and text files
• Save web links for listening
• Scan printed pages
• Paste or type text directly
• Organize everything in one place

OpenVox Reader can generate and play speech locally on your Android device. Once the required voice models are downloaded, you can continue listening without an internet connection.

Natural Voices You’ll Enjoy

Choose from more than 200 voices across 30+ languages and find the voice that best suits your book, article or document.

You can also create custom English voices from a short voice sample using Pocket TTS and listen to your content in a voice you choose.

Speech generation happens locally on your device, allowing downloaded voices and imported content to remain available when you need them.

Private by Design

Your documents are processed locally for speech generation rather than being uploaded to a cloud text-to-speech service.
