SUMMARY
The Microsoft Windows Sound System version 1.0, 1.0a, and 2.0 includes a
tool called Voice Pilot. This tool allows you to command and control
Windows and Windows-based applications by issuing verbal commands. Voice
Pilot can be trained to understand individual voices. The following tips
may help in the Voice Pilot training process and increase the percentage
of correctly recognized words.
Adjust the Recording Control
The input level indicator should register in the yellow when you
speak.
Vary the Closeness of the Microphone
Vary the distance of the microphone from your mouth (the closer the
better). Start with the microphone 8 to 12 inches from your mouth, and
adjust as necessary.
Adjust the Recognition Threshold
If Voice Pilot recognizes commands that you have not issued, you can
increase the closeness of the match between the words you speak and
the command Voice Pilot recognizes, as follows:
Versions 1.0 and 1.0a
- Choose the Menu button, and choose the Options command.
- Adjust the slider to the right (toward the word "Exactly").
Voice Pilot now recognizes a command only if it exactly matches a
command you issue.
If Voice Pilot returns question marks instead of recognizing commands,
you can decrease the closeness of the match between the word you speak
and the command Voice Pilot recognizes by adjusting the slider to the
left (toward the word "approximately").
Version 2.0
- Choose the Preferences Command from the Options Menu.
- Adjust the Confidence Level slider to the right (toward the word
"High").
If Voice Pilot returns question marks instead of recognizing commands,
you can decrease the closeness of the match between the word you speak
and the command Voice Pilot recognizes by adjusting the slider to the
left (toward the word "Low").
Remove and/or Substitute Difficult Words
If Voice Pilot has difficulty recognizing a specific word, you may
want to consider removing the word and creating a new vocabulary item
to perform the command. Voice Pilot is more successful when using
polysyllabic words versus monosyllabic words. For example, if Voice
Pilot has difficulty recognizing the word "Cut," remove "Cut" from the
vocabulary list and add "Cut out" or "delete" or "remove," then train
the word to perform the cut function.
Remove Unused Words from the Active Vocabulary List
Voice Pilot's recognition ability may improve as the number of active
words decreases.
