voice input device A device in which speech is used to input
data or system commands directly into a system. Such equipment involves the use
of speech recognition processes, and can replace or supplement other input
devices. Some voice input devices can recognize spoken words from a predefined
vocabulary, some have to be trained for a particular speaker.
Speech recognition (also known as automatic speech
recognition or computer speech recognition) converts spoken words to
machine-readable input (for example, to key presses, using the binary code for
a string of character codes). The term "voice recognition" is
sometimes incorrectly used to refer to speech recognition, when actually
referring to speaker recognition, which attempts to identify the person
speaking, as opposed to what is being said. Confusingly, journalists and
manufacturers of devices that use speech recognition for control commonly use
the term Voice Recognition when they mean Speech Recognition.
