doesn't recognize my voice

[CM436]

I have a fairly clear voice and a decent microphone. It isn't the best microphone in the world but works pretty clear. I found this a few months ago and gave it a try. It worked perfectly. I took a break from the game and came back to find that the bot doesn't recognize any I say. I used the same microphone on the same computer. Anyone know what I can do to fix it? I tried going into the grammar thing and writing stuff down but the bot is just hearing random words and the list would be hundreds of pages long.
