What is a "speech recognition microphone"..
what does that mean? 

  Incorporating a speech recognition quality microphone means that
the system described ues a microphone with a "flat" frequency reponse
across the frequency range of the captured speech. It also means more than
a good microphone element - it means superior microphone housing design
that avoids echo, and other unwanted acoustic distortions that occur
when even a good microphone is located in a bad housing design.

 A 'good microphone' will always perform sperioir noise canceling; very good
accuracy from a microphone, for speech recognition always requires
unwanted background noise to be eliminated, so not to be 'heard' by
the recognizer and interpreted as speech sounds.

There are typically three types of noise canceling;
1. Using a microphone element with a super cardioid pickup-pattern;
2. Using mechanical noise canceling in the microphone housing design;
3. Electronic or 'active' noise canceling in the circuitry & housing.

 Of the above three noise-canceling mechanisms, either (1) or (2) is usually
better. Speech recognition software typically tests signal to noise ratio when
doing a microphone "setup" or when respective setup wizards are run;
Whenever a new profile is started, for example, with the Microsoft Speech Engine
(which the LOBE is optimized for) the wizard will test & calibrate the
audio input device. "Active" noise canceling has tended to confuse these wizards
or cause false warnings, telling the user the microphone is poor,
when in fact it may be quite good.


What about the wireless aspect?

It's important to note that even when wireless systems incorporate
a "speech recognition quality microphone" element, meeting specifications;
If all the voice bandwidth the microphone element captures isn't
successfully sent to the base unit & then off to the speech recognizer,
then: Even though a microphone is present that meets the necessary
specifications, the system isn't necessarily a wireless system that will render
good voice delivery for speech recognition
.

The LOBE's headset microphones meet speech recognition standards in two areas;
it provides power-consumption friendly noise-canceling via both mechanical
and a basic cardiod pattern pickup-field, and has a rather flat frequency
response plot across the entire spectrum of speech bandwidth it captures.

 Whether for Speech Recognition, or VoIP telephony of any kind, 
we are sure you'll find the LOBE the finest wireless headset system 
available in today's marketplace. Anywhere.

It's that easy.
