It offers full duplex operation for connection with microphone and speakers that is especially well suited to speech recognition applications, and includes a mute switch and indicator lights for power and mute status. Speech Recognition applications on the PC rely on good quality sound input to maintain good performance.</p> <p>The input sound quality is achieved through a combination of a high-quality sound card such as Buddy USB 6G and a good microphone. Buddy USB 6G enables your speech recognition applications to perform equally well on all compatible computing platforms, since the sound card is included on it. Most PCs today have a built in sound card (or chipset), that are often placed close to high electrical noise circuitry like the power supply or other chips working at very high frequencies.This is particularly a problem with most laptop computers. Buddy USB 6G has the unique advantage of being largely immune to those noises as it is external to the computer chassis.
