it is a great project I applaud, but 2 issues need answer: Did you try recording APR9600 chip with line-in not MIC to make sound more clear ? (noice is common when recording with MIC on APR). second: your code can be much shorter if you use matrix for parameters. perhaps one of the code guru;s here can show example, I am not much skilled.
