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 ....

| That sounds interesting, but I don't think it would be practical to make. I think there is a lot of processing power required to interpret the stress in ones voice.
