How to port Microsoft Sam TTS into Godot like KinitoPET?
So you need a speech synthesizer, OS's conveniently come with one built in, and Godot also has the means to make call's to it. https://docs.godotengine.org/en/stable/tutorials/audio/text_to_speech.html The downside is its not going to sound exactly the same on every system. Making a custom TTS engine would be a lot of work, and personally the best solution would be to pre-record the voices and implement them as audio files. More on reddit.com
