AudioBookByMe vs StoryVox

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.

StoryVox turns authors’ manuscripts into AI-narrated audiobooks. Authors can upload EPUB, DOCX, or PDF files and choose from more than 100 advertised voices in English, German, French, Spanish, Italian, Portuguese, Dutch, and Polish. Filters include language, accent, and personality, and a 30-second recording can be used to create a consistent narrator based on the author’s voice. Per-book pronunciation rules and chapter-by-chapter regeneration are available; regenerating a chapter does not require paying for that chapter again. Exports include chapter WAV files or a mastered full-book file for ACX submission. StoryVox says the output can also be uploaded to Audible, Findaway, and Spotify, or sold directly. One credit covers about 1,000 words; an 80,000-word novel typically takes 20–45 minutes to generate and uses about 80 credits. A free account includes 10 credits, and subscriptions start at $9.99/mo. One-time credit packs cost 4.99 USD, 12.99 USD, or 29.99 USD. The maker says users keep commercial rights without royalty sharing and manuscripts are purged from processing storage after generation.
