Frequently asked questions
Comparing AudioDoc and NaturalReader, honestly.
- Why look for a NaturalReader alternative?
- NaturalReader's free tier limits the natural-sounding voices to a daily allowance and keeps the best voices in paid plans. If you listen to full documents regularly, you either hit the cap or buy a subscription. AudioDoc has no daily cap and no premium voice tier.
- Is AudioDoc completely free? No daily minutes?
- Yes. All 24 AI voices, unlimited document length, and unlimited daily use are free. There's no metered allowance to run out of mid-chapter.
- Do I need an account?
- No. Upload and listen as a guest instantly. A free account is optional and only keeps your documents beyond 24 hours.
- When is NaturalReader the better choice?
- If you need commercial redistribution rights for generated audio (voiceovers), OCR for scanned documents, mobile apps, or its education/institution licensing, NaturalReader's paid products cover ground AudioDoc doesn't.
- Which file types does AudioDoc support?
- Text-based PDF, EPUB, and markdown files, plus pasted text in the free TTS studio. Scanned image-only PDFs aren't supported.
- How do the voices compare?
- AudioDoc uses modern neural voices — 24 narrators across nine languages, all free. Upload a document and compare by ear; it takes a minute and costs nothing.
