b. Maximum record time
Maximum record time is the maximum amount of time that speech is recorded. The microphone
will shut off prematurely if you speak longer than maximum record time. However, if you speak for
a shorter period of time than maximum record, the microphone will shut off when trailing silence
expires. Shortening maximum record time may speed up recognition by limiting the amount of
recorded sound processed. By default, VoiceDial will detect the end of speech automatically
in settings where there is little background noise. If maximum record time is set too low, it may
stop recording before capturing all speech. If maximum record time expires before speech is
recorded, speech recognition may fail. To adjust maximum record time, tap and drag the thumb of
the Maximum record time slider to the desired position. Alternatively, you can tap the thumb and
use the navigation pad to scroll the thumb along the slider. The default value is 3 seconds.
c. Customize trailing silence
Trailing silence is the amount of silence, after speech has begun, to indicate that speech has
ended. With this slider, you can control the amount of time the recognizer will wait after speech
before shutting off. Increase this value if speech is cut off while pausing to speak further. Decrease
this value if recognition is taking too long. To adjust trailing silence, tap and drag the thumb of the
Maximum trailing silence slider to the desired position. Alternatively, you can tap the thumb and
use the navigation pad to scroll the thumb along the slider. The default value is 0.5 seconds.
Recog tab
a. Recognition Performance
This setting allows you to adjust the number of computations that will be performed during speech
recognition process to nd a balance between accurate recognition and speed.
Adjust this setting if the recognition process is not recognizing accurately or if it is taking too
long. To customize Recognition Performance, tap and drag the thumb of the slider to the desired
position. Alternatively, you can tap the thumb and use the navigation pad to scroll the thumb
along the slider.
b. Recognition rejection
Recognition rejection adjusts the criteria to accept recognized words as a valid answer. Rais-
ing this value too high increases the chance that background noise may be accepted as a valid
command. Lowering this value too much increases the chance that the words you speak may be
rejected as noise. To customize rejection, tap and drag the thumb of the Recognition rejection
setting slider to the desired position. Alternatively, you can tap the thumb and use the navigation
pad to scroll the thumb along the slider. The default value is 25.
