I am using c# and the text to speech Azure SDK. The voice is very loud relative to other sounds and that is a problem. I can’t use this capability unless I can change only the TTS volume. I found this URL:
SpeechSynthesizer.Properties. I usually find Microsoft’s new documentation very helpful, but that is about worthless. There are properties, but absolutely no way to determine what those properties are. Many of the voice objects are like this. Properties with API for getting known properties and setting them, but no way to know what those properties are.
