I wonder if there is anyone in the world who understands how Microsoft makes installed Voices available to various applications. The whole Windows registry is littered with lists of Voices, but which Voices appear in each list varies. Whoever thought this up must be some kind of sadist.

To the best of my knowledge (based on the work done on my 'TTS to MP3' plugin) the list of Voices calibre will see depends on whether you're using calibre 32-bit or calibre 64-bit. On my own Win10 PC:

calibre 64-bit can see all Voices listed under this registry key:

Code:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Speech\Voices\Tokens

calibre 32-bit (including calibre portable) can see all Voices listed under this registry key:

Code:

HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Microsoft\SPEECH\Voices\Tokens

By default, Windows 10 Cortana Voices do not appear in either of these 2 lists. They can be added but it requires manual editing of the Windows registry, which is either brave or foolhardy depending on your POV. Here's some light(?) reading for the adventurous.

All of the above is based on observation/experiment rather than any real understanding.
