Hi Winterblood,
Yes it sure could! It basically uses the Microsofts
TextToSpeech engine for that. The voices you can have in the engine are dictated by what you have installed on the computer. And when Karsten made our tutorial video, his PC only had a female voice installed.
For the release i just set the gender hint to "Neutral", those hints are are used to let the system Select an appropriate voice. We didn't intend to do anything further with those dummy files, so for our purpose of the plugin this was enough. But you can just as easily take the
source and change that part. But remember, the text to speech engine can only use the voices that you have installed.
The interesting part for your should be the CreateTextToSpeechFile method inside WaveFileHelper.cs:103. You could pass in the Speaker Object and take the information out of the template and change the VoiceGener accordingly, you could even adjust the age
Hope that helps
Best regards
Nico
