Improving recognition

160 There are a number of techniques one can employ to improve or
optimize recognition. Word selection is the primary one. Avoid
homonyms, words that sound alike, for instance, red, bed, said,
and dead. To optimize recognition use dissimilar sounding words.
In many cases a synonym or approximate synonym can be used in
place of a word. For instance use “crimson” or “scarlet” in place of
“red.” For “bed” try using “bunk,” “mattress,” “berth,” or “cot.” For
“said” one may use “spoke,” “voiced,” or “uttered.” For “dead” one
could use “deceased,” “expired,” or “late.” A little thought will solve
any homonym dilemma.

Match environment and equipment
1. Distance. The distance the microphone is away from the
speaker’s mouth should be approximately the same for
training and recognition.
2. Stress. The voice changes under stress or excitement. For
instance, if you are creating a voice-controlled joystick to fly
your favorite military flight simulator, your voice when
engaged in a dogfight yelling “Fire! Fire! Bank Left” will be
quite different than when sitting at your desk calmly
programming your voice into the chip. Therefore, you must try
to emulate the stress and excitement you will feel when
playing the game when programming the voice commands.
