About 10-15 years ago or so, Popular Electronics (I think) had an article
about a human voice micro-tremor analyzer. The distribution/transform of any
utterance was alleged to be indicative of a person's mood and/or honesty. It
was said to work even over the phone or over broadcast media.

Subject: Human Mood Dection (Through Voice)
Greetings All,
(I'm new to the Mindstorms, so bare with me if this has been done already).
Does anyone think this is feasible? (This could be implemented as a
sensor). Basically a voice "reader" that could be used to determine
a persons mood, or even for voice recognition.
The first step is not to difficult. A 20$ Digital Voice recorder can easily
be acquired from Radio Shack.
The second step, would be the tough part. As far as on a computer end,
one could do this. There's many lie-detection software programs out there
(whether they work or not is a different issue, but they do tell quite well
if there is Tension in the voice - which is all that we would need). Plus
there
is voice detection software I've used that I never needs to be trained.
But,
once again, we don't need complete recognition.
I think this could be implemented in a separate unit, which would then
output RAW data (to not kill the Lego CPU's processing power). This
shouldn't be to hard - a mood detection algorithm wouldn't be terribly
difficult. Just off the top of my head, I guess the algorithm could search
for
- sudden changes in pitch
- jittery speech
- pauses
But, I'm sure Lie detection and Mood is well documented and could be easily
researched.
If anyone knows of a project like this already in the making, please let me
know.
Otherwise, I would definitely be interested giving a whirl at something like
this.
The only question is the feasibility of it ....
