Not all voices can be used to save as an MP3 audio file. The available voices are limited to only
the Nuance voices. In case no Nuance voice is installed, the MP3 button will be greyed out and
this option is not available for the selected language.
Only one voice will be used for the entire MP3 file. Automatically switching between languages
within an MP3 audio file is not supported.
Saving a document in MP3, DOCX or e-PUB takes longer than the standard format. Especially
saving a multipage document in MP3 format could take several minutes.
After you selected the format to save the document in, you will be asked if you would like to save
your document with a voice label.
