Convert EPUB to OGG

If you are trying to transform your digital book into an audiobook, you have several options for a direct conversion. Unfortunately, you will not be able to convert Open eBook files directly to Ogg Vorbis Audio files (.epub to .ogg conversion); at least not without a simple workaround. 

Tools, such as Balabolka or Narrator or new AI audio online services, allow users to extract texts from EPUB ebooks and export them as speech in MP3 audio format. You can then easily convert MP3 to OGG.
