1
00:00:25,890 --> 00:00:16,960
monitor to alpha Bravo

00:00:25,900 --> 00:00:29,000
change rate

3
00:00:34,010 --> 00:00:31,550
didn't recognize it it won't play okay

4
00:00:40,360 --> 00:00:34,020
so the Winx I know that it took the

5
00:00:44,049 --> 00:00:40,370
change down

6
00:00:44,059 --> 00:00:48,930
change rate

7
00:00:54,060 --> 00:00:51,979
stop Marcus are you probably marking us

8
00:01:00,110 --> 00:00:54,070
but I'm gonna mark some of the ones that

9
00:01:00,120 --> 00:01:03,099
go

10
00:01:03,109 --> 00:01:13,109
zoom in

11
00:01:13,119 --> 00:01:15,910
right

12
00:01:20,770 --> 00:01:18,830
change rate

13
00:01:25,550 --> 00:01:20,780
right

14
00:01:41,390 --> 00:01:27,560
I think I would cycle a whole thing one

15
00:01:50,110 --> 00:01:43,770
okay

16
00:01:55,800 --> 00:01:50,120
monitor one monitor one monitor two

17
00:02:00,210 --> 00:01:58,219
standby

18
00:02:06,370 --> 00:02:00,220
activate

19
00:02:10,279 --> 00:02:06,380
go

20
00:02:10,289 --> 00:02:19,839
right stop

21
00:02:30,460 --> 00:02:22,170
change rate

22
00:02:36,400 --> 00:02:32,320
easy

23
00:02:38,690 --> 00:02:36,410
so cameras

24
00:02:40,640 --> 00:02:38,700
no cameras

25
00:02:44,290 --> 00:02:40,650
more

26
00:02:51,680 --> 00:02:44,300
too much

27
00:02:51,690 --> 00:02:59,559
change rate

28
00:02:59,569 --> 00:03:10,460
tilt up

29
00:03:10,470 --> 00:03:15,160
right

30
00:03:22,890 --> 00:03:17,120
stop

31
00:03:27,010 --> 00:03:25,030
tilt up

32
00:03:39,280 --> 00:03:27,020
stop

33
00:03:41,380 --> 00:03:39,290
select one time ideally the mood active

34
00:03:54,099 --> 00:03:41,390
LED is on the stamp a lit is also I beat

35
00:03:55,720 --> 00:03:54,109
you back the baby so if we I'll talk to

36
00:03:56,849 --> 00:03:55,730
chef about how we're gonna manage that

37
00:03:59,349 --> 00:03:56,859
okay

38
00:04:02,080 --> 00:03:59,359
like I told chef what's most important

39
00:04:04,089 --> 00:04:02,090
to that are most affects your opinion

40
00:04:09,250 --> 00:04:04,099
sure that is our most important feedback

41
00:04:14,360 --> 00:04:11,360
this would be where you'd be activated

42
00:04:23,050 --> 00:04:14,370
if you wanted to or as required that's

43
00:04:27,770 --> 00:04:25,970
but the data is compared against ground

44
00:04:30,590 --> 00:04:27,780
data that we acquired during astronaut

45
00:04:32,720 --> 00:04:30,600
training hopefully we'll be able to see

46
00:04:35,150 --> 00:04:32,730
are the effects the space environment

47
00:04:38,620 --> 00:04:35,160
has on the speech process and voice

48
00:04:44,930 --> 00:04:40,970
there are several successful

49
00:04:47,290 --> 00:04:44,940
applications of voice commanding systems

50
00:04:50,150 --> 00:04:47,300
in in the commercial sector for example

51
00:04:52,520 --> 00:04:50,160
in the area of aid to the handicapped

52
00:04:56,390 --> 00:04:52,530
and handicapped person can control by

53
00:04:59,780 --> 00:04:56,400
voice a motorized wheelchair medical

54
00:05:03,170 --> 00:04:59,790
reporting currently doctors are using

55
00:05:04,880 --> 00:05:03,180
voice recognition to to generate medical

56
00:05:07,880 --> 00:05:04,890
reports whereby they're looking at a

57
00:05:09,710 --> 00:05:07,890
x-ray for example and are examining it

58
00:05:11,660 --> 00:05:09,720
and are in putting words into the

59
00:05:13,760 --> 00:05:11,670
recognizer that it recognizes in its

60
00:05:16,700 --> 00:05:13,770
generating report about the doctor's

61
00:05:18,820 --> 00:05:16,710
examination other applications is access

62
00:05:21,470 --> 00:05:18,830
control where they use a speaker

63
00:05:23,210 --> 00:05:21,480
verification system is the person that

64
00:05:25,730 --> 00:05:23,220
wants to get into this door truly the

65
00:05:27,860 --> 00:05:25,740
person it is and they use a specific

66
00:05:29,930 --> 00:05:27,870
voice print algorithm to try and

67
00:05:33,620 --> 00:05:29,940
determine if this person is indeed the

68
00:05:35,540 --> 00:05:33,630
person he says he is the system that we

69
00:05:38,150 --> 00:05:35,550
use is what they call speaker dependence

70
00:05:40,070 --> 00:05:38,160
system which means that the crew each

71
00:05:42,410 --> 00:05:40,080
crew person has to train the system

72
00:05:44,570 --> 00:05:42,420
before it can use it training consists

73
00:05:46,910 --> 00:05:44,580
of going through our vocabulary times

74
00:05:49,310 --> 00:05:46,920
it's saying its word each word is then

75
00:05:51,230 --> 00:05:49,320
digitized and stored in memory as a

76
00:05:53,750 --> 00:05:51,240
template or voice print similar to a

77
00:05:55,880 --> 00:05:53,760
person's thumbprint and then all those

78
00:05:59,010 --> 00:05:55,890
words are then saved according to each

79
00:06:03,129 --> 00:06:02,589
okay when the astronaut wants to use the

80
00:06:04,330 --> 00:06:03,139
system

81
00:06:06,999 --> 00:06:04,340
he would come in you know plug in his

82
00:06:08,740 --> 00:06:07,009
headset and plug in the display in the

83
00:06:11,589 --> 00:06:08,750
shorting plug and then all he has to do

84
00:06:14,249 --> 00:06:11,599
is turn on the power switch to on and

85
00:06:17,649 --> 00:06:14,259
that's the only manual step necessary

86
00:06:19,119 --> 00:06:17,659
after when the system powers up then the

87
00:06:21,279 --> 00:06:19,129
system automatically krons

88
00:06:23,649 --> 00:06:21,289
yes not to say his name when it says his

89
00:06:25,420 --> 00:06:23,659
name it recognizes who he is would go

90
00:06:28,180 --> 00:06:25,430
out and load his templates from memory

91
00:06:30,219 --> 00:06:28,190
into the recognizer then when he wants

92
00:06:32,529 --> 00:06:30,229
to control a system you'll say a command

93
00:06:34,180 --> 00:06:32,539
it takes that word and digitizes it and

94
00:06:36,279 --> 00:06:34,190
compares it with the words that were

95
00:06:38,559 --> 00:06:36,289
loaded into the recognizer if it finds a

96
00:06:40,719 --> 00:06:38,569
match it sends that infrared sensing

97
00:06:42,520 --> 00:06:40,729
information from the recognizer to are

98
00:06:44,559 --> 00:06:42,530
controlling Hardware where we process

99
00:06:47,110 --> 00:06:44,569
information figure out what word it was

100
00:06:49,089 --> 00:06:47,120
and then send the appropriate signal out

101
00:06:50,749 --> 00:06:49,099
to the CCTV system to control the camera

102
00:06:53,719 --> 00:06:50,759
or movement or

103
00:06:55,790 --> 00:06:53,729
whatever the function happens the voice

104
00:06:57,920 --> 00:06:55,800
command system is the first experiment

105
00:07:00,230 --> 00:06:57,930
to be flown in space which uses voices

106
00:07:02,299 --> 00:07:00,240
to control we think this is going to be

107
00:07:04,640 --> 00:07:02,309
useful to be astronauts for two reasons

108
00:07:06,409 --> 00:07:04,650
and the first reason is that by having a

109
00:07:08,179 --> 00:07:06,419
system which is voice controlled the

110
00:07:11,179 --> 00:07:08,189
astronauts hands and eyes are free to

111
00:07:13,519 --> 00:07:11,189
perform other tasks the second reason is

112
00:07:15,200 --> 00:07:13,529
that by using a voice control system it

113
00:07:17,510 --> 00:07:15,210
isn't necessary for you to be in the

114
00:07:18,980 --> 00:07:17,520
location where the system is in order to

115
00:07:23,929 --> 00:07:18,990
control it so you're free to move around

116
00:07:26,029 --> 00:07:23,939
and you can be remotely located no we

117
00:07:28,399 --> 00:07:26,039
can have as many people as want to can

118
00:07:32,329 --> 00:07:28,409
use our system we have it set up so that

119
00:07:34,610 --> 00:07:32,339
only five five people can actually have

120
00:07:37,279 --> 00:07:34,620
their voices put on to e-square bumps

121
00:07:40,100 --> 00:07:37,289
but we also have the ability to retrain

122
00:07:41,689 --> 00:07:40,110
templates real-time so anybody who wants

123
00:07:43,760 --> 00:07:41,699
to use the system may not already have

124
00:07:45,320 --> 00:07:43,770
theirs templates made but they can come

125
00:07:47,389 --> 00:07:45,330
up to the system and make their template

126
00:07:48,679 --> 00:07:47,399
anytime they want so we're not limited

127
00:07:58,370 --> 00:07:48,689
on the number of people who can use the

128
00:08:02,170 --> 00:08:00,500
all right well we have 40 commands that

129
00:08:04,580 --> 00:08:02,180
are possible on the voice command system

130
00:08:07,070 --> 00:08:04,590
most of these commands are exact

131
00:08:09,230 --> 00:08:07,080
duplicates to what are on a CCTV manual

132
00:08:11,240 --> 00:08:09,240
switch panel these are selecting

133
00:08:12,830 --> 00:08:11,250
monitors cameras and working in the

134
00:08:16,010 --> 00:08:12,840
camera motions like panning and tilting

135
00:08:18,350 --> 00:08:16,020
zooming focusing all of those we also

136
00:08:20,810 --> 00:08:18,360
have some VCS unique commands which are

137
00:08:23,600 --> 00:08:20,820
used to activate the system deactivate

138
00:08:26,690 --> 00:08:23,610
the system identify the user and we also

139
00:08:29,510 --> 00:08:26,700
have some special macro commands for

140
00:08:31,160 --> 00:08:29,520
example we have a command that will stow

141
00:08:33,200 --> 00:08:31,170
all of the cameras in the payload Bay

142
00:08:35,270 --> 00:08:33,210
into the position that they have to be

143
00:08:38,300 --> 00:08:35,280
in for launch and entry simply by saying

144
00:08:40,520 --> 00:08:38,310
still cameras so we also have some

145
00:08:45,750 --> 00:08:40,530
special features that the manual switch

146
00:08:48,930 --> 00:08:47,699
well the way we chose the words to use

147
00:08:51,360 --> 00:08:48,940
is because they're the words that are

148
00:08:52,650 --> 00:08:51,370
actually on the switch panel so they're

149
00:08:55,410 --> 00:08:52,660
the ones that are familiar with when

150
00:08:58,199 --> 00:08:55,420
they think of moving a camera they think

151
00:09:00,629 --> 00:08:58,209
of tilting it up so we selected all of

152
00:09:02,900 --> 00:09:00,639
those works now they did tailor their

153
00:09:04,620 --> 00:09:02,910
vocabulary to their personal and use

154
00:09:06,509 --> 00:09:04,630
words that they were the most

155
00:09:07,319 --> 00:09:06,519
comfortable with words that work the

156
00:09:09,870 --> 00:09:07,329
best for them

157
00:09:11,370 --> 00:09:09,880
so both of our astronauts have have a

158
00:09:13,379 --> 00:09:11,380
different vocabulary but they're also

159
00:09:15,090 --> 00:09:13,389
very similar and they're the words that

160
00:09:24,370 --> 00:09:15,100
make sense to them and that's how we

161
00:09:29,260 --> 00:09:26,590
well there's not a lot known about the

162
00:09:31,660 --> 00:09:29,270
effects of microgravity on the voice we

163
00:09:33,790 --> 00:09:31,670
do know that in zero gravity that the

164
00:09:36,820 --> 00:09:33,800
position and the shape of the lungs and

165
00:09:39,550 --> 00:09:36,830
diaphragm are altered now this cause is

166
00:09:41,770 --> 00:09:39,560
a great enough distortion in the voice

167
00:09:44,590 --> 00:09:41,780
good recognition could be difficult to

168
00:09:49,720 --> 00:09:44,600
get so we're expecting that this may be

169
00:09:51,550 --> 00:09:49,730
a problem well what we're going to do is

170
00:09:53,860 --> 00:09:51,560
that if the astronauts do find that they

171
00:09:55,660 --> 00:09:53,870
have trouble getting recognition we have

172
00:09:58,300 --> 00:09:55,670
the ability to remake their templates

173
00:10:00,190 --> 00:09:58,310
real time so simply by clicking this

174
00:10:01,780 --> 00:10:00,200
mode switch try the Fitzsimmons

175
00:10:04,270 --> 00:10:01,790
automatically put into the template

176
00:10:06,220 --> 00:10:04,280
making mode and our system will prompt

177
00:10:08,020 --> 00:10:06,230
them through the entire vocabulary list

178
00:10:09,490 --> 00:10:08,030
they'll say each word twice and they'll

179
00:10:11,050 --> 00:10:09,500
have a brand new set of templates that

180
00:10:15,850 --> 00:10:11,060
are real and representative of their

181
00:10:17,050 --> 00:10:15,860
voice at that time it feels so fabulous

182
00:10:18,850 --> 00:10:17,060
you know there's times when you really

183
00:10:21,220 --> 00:10:18,860
think it isn't gonna fly it's just it's

184
00:10:22,930 --> 00:10:21,230
not gonna go and now not only is it

185
00:10:25,120 --> 00:10:22,940
going to go but our astronauts love it

186
00:10:26,920 --> 00:10:25,130
they love it they're having fun with it

187
00:10:29,320 --> 00:10:26,930
everybody we've shown it to like that

188
00:10:31,240 --> 00:10:29,330
people are coming up out of the corners

189
00:10:32,290 --> 00:10:31,250
with ideas of how to use it and it
