It'd take a lot of speech data to make a diagnosis, and I'd imagine it'd be error-prone at first. As for how to differentiate hypomania from excitement, I'm skeptical that it can be done. But if someone who usually talks 50% of the time in conversations is taking 95% of the time, and this persists over weeks, there's a signal there. Also, hypomania tends to produce a lot of run-on and deeply-nested (even Lispy (as in having multiple levels of implicit parentheses)) sentences. Not enough personal experience with actual mania (as opposed to hypomania) to opine on it or guess what its signals might be. Only had it a couple times and none recently.
