Read PDF books with speech, convert text to audio, and listen offline in Vietnamese or English. Options for voice, save reading position, and export audio in multiple parts.

FolioTone helps you convert PDF books and text into Vietnamese speech right on your iPhone and iPad.

Import books from the Files app, open the page you want to read, and select Listen from the top of the page or Listen from this position. When enabling continuous listening mode, FolioTone will automatically read the following pages and can turn pages synchronously with the audio.
