TV. In general, you will have best results when inVoca is between
12 and 36 inches from your mouth in a quiet room, and between 12
and 24 inches in a noisy room. You should try to hold inVoca at the
same distance from your mouth during training as you will when
you are using it.
L As with any remote control, the infrared LEDs must be pointing
at the device to be controlled when either a button is pressed or a
voice command is utilized. 7
Choosing Voice Commands
inVoca allows you to associate any voice command with any button.
While it might be tempting to program a voice command for every
button, this is usually not recommended because in operation you
would then need to pause, say the first number, then pause and say the
next number. It is more useful to assign a voice command to a macro.
For example you can use the command "HBO" to set your cable box
to channel 17 (or whatever channel HBO is on your neighborhood).
You could program the voice command as "Channel 17" but "HBO"
is usually easier to remember. Use commands that are easy to
remember!
Try to choose voice commands that are distinct from one another. For
example, "CSPN" and "ESPN" will probably sound too similar for
most speakers. Changing one of these to something that sounds
different (for example, C-SPAN instead of CSPN) will provide better
results. Multi-syllable or two-word commands work better than short
words because inVoca has more information to work with and can
better understand the command. For example "Quiet" is a better word
choice than "Mute" because it contains more sound information. Also,
having commands of different length will make it easier for inVoca to
distinguish them.
You may wish to associate the words "Louder" and "Softer" with the
volume-up and volume-down buttons. But for some people "louder"
sounds a lot like "power" (at least a far as inVoca is concerned), so

you may inadvertently shut off your TV instead of making it louder.
Using the words "TV Power" or "power on" will make it easier for
inVoca to distinguish the commands. Also, remember if you make the
TV too loud, inVoca may have a hard time hearing your commands
over the sound of the TV.
"Next Channel" and "Previous Channel" will often provide better
results than "channel up" and "channel down." See "Suggested
Vocabulary" (page 41) for more suggestions.
Changing and Deleting Voice Commands
From time to time you may wish to delete or change a voice
command. For example, you may decide you would prefer a different
command that is easier to say or remember. Sometimes, if a
command is not working well, there may have been some background
noise when you recorded the command, and performance will be
improved if you erase, then re-record it.
To delete a voice command:
1. Press and release the [Æ] button, then press the [Train] button.
2. inVoca will respond with “Beep. Say a word.”
3. Say the command you wish to erase.
4. inVoca will respond with "button erased" or "macro erased."
To Cancel A Training Operation
You may elect not to train a command after you have pressed the
[Train] button, or after beginning to erase a personality. If you do
not speak after pressing the [Train] button, inVoca will respond
three times with the words "too soft." You have the choice of waiting
for inVoca to repeat this phrase or you may simply press any button
to cancel the operation.
