You're working on voice recognition software, right?   ;-)

If I understand what you're trying to do (which is doubtful), you might
need to be looking at what's happening between speaker toggles. Hitting
the speaker with any value makes it click once, so it is the delay in
between clicks that determines the pitch. You'll have to have a look at
your ML sound routine to figure out how the delay is generated.
