That did it. But how could I create an array of them, so that it's not needed to specify just 2? That way, it would keep creating new voices each time I clicked the command button. Example: When I quickly click the Command Button 5 times, it creates 5 new voices, all speaking over each other.
Then, you should experiment with the stuff bit.
I don't know what's your actual idea behind this. However, just packing the stuff into a usercontrol and use it appropriately would be a better solution. Another would be to directly use a class module with the stuff, but may have problems with asynchronous speaking.
The attached one is a small demonstration on the usercontrol approach, which you might adopt for your need. Just tested on both Win7 and Win10 and seems working well.
