OpenVox Reader

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, resting 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 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 device, so once the required voices are downloaded, you can listen 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.

Adjust playback from 0.5x all the way to 2.5x with smooth, pitch-preserving audio.

Choose convenient presets including:

Faster playback is supported with optimized buffering and accurate elapsed and remaining-time calculations.
