Special considerations for speech dictation applications:
When upgrading to a new microphone for speech recognition applications,
always create a new user file. For large vocabulary dictation systems, this usually
involves running the application’s Audio Setup Wizard to adjust the volume, and
going through a new enrollment process to train the system for the new acoustic
properties of the microphone.
It is very important to position the microphone properly for best performance on
speech dictation systems. Please follow these positioning guidelines when using
Telex microphones and headsets for speech dictation.
For Telex headsets with noise canceling microphones:
Position the microphone ¼” to ½” from your lips, off the corner of your mouth.
Be sure that the microphone is out of the way from any air blasts from your nose
or mouth when speaking. Use the microphone wind screen for best performance.
For M-60 Super-Directional Desktop Microphone:
Position the microphone on your desktop about 12” to 24” from your lips and
point it directly at your mouth. Adjust the distance from your mouth depending
on the noise level in your environment. For louder environments, position the
microphone at 12”. For quiet environments, position the microphone at 18-24”.
The M-60 uses a highly directional pick up pattern to enhance voice input and
cancel background noises. Small, closed rooms (under 64 sq. ft.) with hard walls
and floors can adversely affect the performance of far-field, directional
microphone structures like the M-60. This can be particularly evident if a hard
wall is located directly behind the talker, enabling noise to be reflected directly
into the front of the microphone at the same angle as your voice. Try to position
the microphone so that it points away from noise sources and reflective walls.
Safety

heat registers and other similar appliances.
Keep your headset or microphone away from liquids.
Protect your headset or microphone from dampness.
