<p>I think at least some of this is out of scope. Maybe Q1 is ok, but I don't know if acoustic HMMs are any different from HMMs in other areas. If the question is about training HMMs generally, it would be fine. But if acoustic HMMs are very different from other HMMs, then maybe it would be to application-specific for this site.</p>

<p>In general, questions that require a lot of application-specific knowledge should be out-of-scope in my view.</p>
