AudioBookByMe vs Vox9

AudioBookByMe turns documents and scanned pages into audiobook-quality MP3 audio using AI text-to-speech. It accepts PDF, EPUB and plain text files, as well as scanned PDFs and JPG or PNG book-page photos, which it processes with OCR. Its parser can identify chapter headings and skip contents, copyright and index sections. The catalog contains 66 AI voices in 8 languages; voice cloning uses a 10-second sample and supports any accent or language. A pronunciation dictionary lets users save word-replacement corrections for reuse across chapters. Audio is processed in mono at 44.1 kHz and 192 kbps CBR, with loudness normalized to -23 LUFS. AudioBookByMe says its ACX-ready files can be published to Audible, Apple Books, Google Play, Spotify and Findaway. Users retain rights to their books and generated audio while granting a limited license for processing. The free tier allows one conversion per month and adds a brief spoken watermark. Paid plans start at $19.99/mo.

Vox9 is an audiobook platform for serialized fiction, where listeners can stream episodes for free and independent authors can publish them. Its genres include science fiction, fantasy, HFY and horror. Authors may narrate with more than 100 AI voices or upload human narration; episodes can pair audio with synchronized scene images and captions, and existing YouTube videos can be imported as episodes. Listener access is free, and no account is needed to begin listening. A free author account includes 100,000 narration characters per month, described as roughly 1.5 hours of audio, with no credit card required. Paid plans start at $7.99/mo; one-time credit packs cost $3.00, $12.00 or $22.00, and purchased credits do not expire. Authors keep 50% of subscription payments and 80% of tips, with PayPal payouts once the balance reaches $9. Vox9 is available on Android, iOS and the web. The maker says authors retain ownership of uploaded text and MP3 audio, can delete their content, and their materials are not used to train AI models.
