Special Considerations for Speech Dictation
When changing the sound system (sound card or USB Adapter) or a
microphone for speech recognition applications, you must always run the
audio setup wizard, and optionally a short training session for proper change
over.
Failing to do that will almost certainly degrade recognition accuracy. As an
option you can create a brand new user profile or a new input source for your
new audio system.
It is important to position the microphone properly with respect to your
mouth for best performance of the speech recognition systems. Normally the
end of the microphone boom should be 1cm-4cm from the corner of your
mouth.
Additionally you can do the following:
a)
When running a test for your microphone, put pauses in between
phrases, for example: “In this step (1 second pause) the computer
checks the audio input (1 second pause) of your sound
system” Silence is sampled as well as speech, this allows comparison
between speech and ambient noise.
b)
Speak clearly and evenly like newscasters.
c)
Enunciate all syllables in each word. Many have a tendency to drop
trailing syllables in many words.
