Synchronize the contact list
The contact name recognizer may be manually synchronized with Contacts by tapping the
list box column header entitled Sync. This is recommended when you change the spelling
of a name in the Contacts list.
Timing tab
Customize leading silence
"Leading silence" sets the maximum time the microphone will listen for speech to begin.
If speech is not detected within this amount of time, the microphone will shut off. Adjust
leading silence to allow for adequate pause before speech. To adjust leading silence,
tap and drag the thumb of the Maximum leading silence slider to the desired position.
Alternatively, you can tap the thumb and use the navigation pad to scroll the thumb along
the slider. Check the No limit box to allow the microphone to stay on indefinitely, listening
for speech to begin. No limit is the default.
Maximum record time
"Maximum record time" is the maximum amount of time that speech will be 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.
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.
