[microsound] Speech Analysis Question...

[Phil Thomson]

fscape has a utility that can split a sound into chunks of
user-defined length, analyze and compare the chunks and then arrange
the chunks according to their similarity in a certain regard, for
example, amplitude or noisiness.  It may not do exactly what you want
it to do, but still might be useful to try or to generate ideas.
That's what i can think of off the top of my head.
