I'm guessing it's an error with the initiation/construction, but the parameters seem to be the correct ones and I can't find any other issues. Here's the entire activity code. The text to speech methods and the method that calls it are at the very bottom, and the oninit method is soon after the on create. When ran, it doesn't crash, it activates the speech engine, but never talks. I put the console messages in the errors section
