Downloading the TTS audios as mp3 file is available with a separate product - Vocalware Export.
Vocalware Export also provides a license to use the downloaded audio in your online and offline media (such as youtube videos, corporate tutorial videos etc.).
A license for use in broadcast media & games can also be made available per title or episode.
