The great thing about an Array microphone is that it tunes out everything around it except for the voice of the person speaking, without them having to wear a headset. But just what exactly is an array microphone?

An array microphone is made up of set of microphones that are able to operate together at once. Such systems will often be found in devices so that voices can be extracted away from other ambient sounds. Such devices we are talking about are hearing aids, telephones and speech/voice recognition systems.

Normally, these microphones will be linked to a computer so that they are able to record and then interpret the results of what they have gathered into a coherent structure. The latest software package from Microsoft known as Windows Vista now comes with a built in support system for people to be able to use array microphones with it. This then means that the accuracy of their speech recognition software feature is also greatly increased.

One of the most well known of all array microphones is the Acoustic Magic Voice Tracker, which can be used with Dragon Naturally Speaking. It contains a listening beam (similar to a search light) which is able to locate and then electronically steer itself towards the person who is talking. Also, it is able to reduce the amount of background noise that the microphone picks up which then results in not only less low recognition errors occurring, but also it is able to respond faster even at long distances. This particular device is ideal for use in teleconferencing situations as it has a 180 degree range for scanning. This means that the microphone is able to rapidly steer towards those individuals who are taking part in the conference as they speak, and at all times they will be heard quite clearly by those elsewhere.

With an array microphone, a person does not need to sit straight in front of it. Rather, they now have the ability to be able to move around. Plus, it is extremely easy to use and is extremely reliable and rugged, because it contains no moving parts. All a person needs to do in order to get their array microphone working is to plug it in to their PC's sound card and also ensure that it is connected to a power supply. Because it has its own power supply, this then means that it actually does not actually decrease the processing capacity of your PC.

If you are looking for a microphone that is able to tune everything else out around you except for your own voice without you having to wear headphones, then you should consider purchasing yourself an array microphone such as the Acoustic Magic Voice Tracker.
