A microphone is an input device
that translates sound into electric current, which the computer will then
digitise. Initially this was designed as
a special device for the handicapped and required special software.
However, more and more Voice-Recognition software is becoming
available, allowing users to “speak” text rather than type it in. Voice Recognition applications usually have
to be “trained” to understand different voices.
Microphones are also becoming
increasingly important as Internet tools, and the Voice Over Internet Protocol is allowing verbal conversations and Voice Messaging across computer
networks.
Computers that are equipped with
a microphone, sound card and speakers can be used for telephone network
switching, and this is becoming increasingly important in large call centres.
