Compare SonikaAI, Speechify and NaturalReader: which files you can narrate, whether translation is included, and whether you can download it.
Start with SonikaAI if the book or document is in a foreign language and you want to listen in your own: the translation and the narration happen in a single run. If the file is already in the language you need, SonikaAI lets you listen to the main text only — without the running heads and notes; and if scans or a wider choice of languages matter, the table shows where the competitors are stronger.

The competitors’ capabilities are taken from their own official descriptions. This compares features, not the quality of the narration.
If the document or the book is in another language, SonikaAI translates and narrates it in one run. You do not have to translate the text somewhere first and then go looking for something to read it aloud.
Listen to the main text only — without the recognised running heads, notes and bibliographic references that interrupt the flow. If you want them, choose full narration. The audio format does not change either way.
The M4A with chapters or the MP3 you download is yours: play it offline in your own player, not only inside the service’s app.
SonikaAI needs a PDF with a text layer: scanned pages that are only images are not supported at the moment. If paper or scans are your main source, then for that particular file Speechify or NaturalReader, with their text recognition, may serve you better.
Turn a PDF, Word file, EPUB or plain text into audio without translating it. Choose a voice, pick main text or full narration, and download the finished file.
Translate a book or document and get the audio in the same language as the text, from a single upload. Listen to study and work material whenever it suits you.
Preview voice samples for every SonikaAI plan and choose the narration quality level that fits you.
Start with a free sample to judge the voice on your own book or document. For the full narration you can pay once without a subscription, or take a monthly plan.
