select one time ideally the mood active
LED is on the stamp a lit is also I beat
you back the baby so if we I'll talk to
chef about how we're gonna manage that
okay
like I told chef what's most important
to that are most affects your opinion
sure that is our most important feedback
so you come back happy whatever
this would be where you'd be activated
if you wanted to or as required that's
better
but the data is compared against ground
data that we acquired during astronaut
training hopefully we'll be able to see
are the effects the space environment
has on the speech process and voice
recognition
there are several successful
applications of voice commanding systems
in in the commercial sector for example
in the area of aid to the handicapped
and handicapped person can control by
voice a motorized wheelchair medical
reporting currently doctors are using
voice recognition to to generate medical
reports whereby they're looking at a
x-ray for example and are examining it
and are in putting words into the
recognizer that it recognizes in its
generating report about the doctor's
examination other applications is access
control where they use a speaker
verification system is the person that
wants to get into this door truly the
person it is and they use a specific
voice print algorithm to try and
determine if this person is indeed the
person he says he is the system that we
use is what they call speaker dependence
system which means that the crew each
crew person has to train the system
before it can use it training consists
of going through our vocabulary times
it's saying its word each word is then
digitized and stored in memory as a
template or voice print similar to a
person's thumbprint and then all those
words are then saved according to each
person as their
okay when the astronaut wants to use the
system
he would come in you know plug in his
headset and plug in the display in the
shorting plug and then all he has to do
is turn on the power switch to on and
that's the only manual step necessary
after when the system powers up then the
system automatically krons
yes not to say his name when it says his
name it recognizes who he is would go
out and load his templates from memory
into the recognizer then when he wants
to control a system you'll say a command
it takes that word and digitizes it and
compares it with the words that were
loaded into the recognizer if it finds a
match it sends that infrared sensing
information from the recognizer to are
controlling Hardware where we process
information figure out what word it was
and then send the appropriate signal out
to the CCTV system to control the camera
or movement or
whatever the function happens the voice
command system is the first experiment
to be flown in space which uses voices
to control we think this is going to be
useful to be astronauts for two reasons
and the first reason is that by having a
system which is voice controlled the
astronauts hands and eyes are free to
perform other tasks the second reason is
that by using a voice control system it
isn't necessary for you to be in the
location where the system is in order to
control it so you're free to move around
and you can be remotely located no we
can have as many people as want to can
use our system we have it set up so that
only five five people can actually have
their voices put on to e-square bumps
but we also have the ability to retrain
templates real-time so anybody who wants
to use the system may not already have
theirs templates made but they can come
up to the system and make their template
anytime they want so we're not limited
on the number of people who can use the
system
all right well we have 40 commands that
are possible on the voice command system
most of these commands are exact
duplicates to what are on a CCTV manual
switch panel these are selecting
monitors cameras and working in the
camera motions like panning and tilting
zooming focusing all of those we also
have some VCS unique commands which are
used to activate the system deactivate
the system identify the user and we also
have some special macro commands for
example we have a command that will stow
all of the cameras in the payload Bay
into the position that they have to be
in for launch and entry simply by saying
still cameras so we also have some
special features that the manual switch
panel doesn't have
well the way we chose the words to use
is because they're the words that are
actually on the switch panel so they're
the ones that are familiar with when
they think of moving a camera they think
of tilting it up so we selected all of
those works now they did tailor their
vocabulary to their personal and use
words that they were the most
comfortable with words that work the
best for them
so both of our astronauts have have a
different vocabulary but they're also
very similar and they're the words that
make sense to them and that's how we
came up with our vocabulary
well there's not a lot known about the
effects of microgravity on the voice we
do know that in zero gravity that the
position and the shape of the lungs and
diaphragm are altered now this cause is
a great enough distortion in the voice
good recognition could be difficult to
get so we're expecting that this may be
a problem well what we're going to do is
that if the astronauts do find that they
have trouble getting recognition we have
the ability to remake their templates
real time so simply by clicking this
mode switch try the Fitzsimmons
automatically put into the template
making mode and our system will prompt
them through the entire vocabulary list
they'll say each word twice and they'll
have a brand new set of templates that
are real and representative of their
voice at that time it feels so fabulous
you know there's times when you really
think it isn't gonna fly it's just it's
not gonna go and now not only is it
going to go but our astronauts love it
they love it they're having fun with it
everybody we've shown it to like that
people are coming up out of the corners
with ideas of how to use it and it
really makes you feel like you've
accomplished a lot
