I setup a new server for the IVM software to run on and I am still having the same issues. When I first installed, I have Microsoft SAM which works fine.
Then I install the Mary and Mike voices from Microsoft which show in the list of synthesized voices.
When I attempt to synthesize text in an OGM, it doesn't matter which voice I select from the list, it always sounds exactly like the original default (SAM). I just want to see if this feature actually works before I buy high-end voices to be applied in the IVM sofware.
