If you're not using Azure, then the voices are going to be based on your Windows settings:
1. Search for "speech" in the Windows 10 search bar
2. Select "Speech Settings"
3. Under Voices, choose a different voice.
I'm actually having an opposite dilemma than you. I use Azure and wish I could get a female voice to go along with my female pilot! If anyone has a female voice using Azure, please let me know !
