Dailydave: Re: Vista speach recognition

The source side needs to be a synchronized stream so 
that all the computers are yelling at the same time.

Said stream needs to have the necessary commands in
it to recruit others to the chorus, i.e., if you 
hear it, you are compelled to join in.  The Pied
Piper comes to the Internet...

In that same theoretical world where you begin with
"Assume a spherical cow of uniform density," you can
say that a single machine yelling for others to join
in will recruit any other within the range of its
voice but as new recruits join in, the synchronized
yelling gets louder.  If the recruited machines are
predictably spaced on a uniform grid, then the sound 
density will be calculable by the R-squared falloff
of intensity from the effective center of the speakers.
The folks who do active phased arrays would know how
to do the math, but a time-delay beamformer could,
in theory, direct the "beam" of sound wherever you 
like it.
