Speech or voice recognition is the ability of a machine or program to
recognize and carry out voice commands or take dictation.
In general, speech recognition involves the ability to match a voice pattern against a provided or acquired vocabulary.
Currently, full dictation speech
recognition programs are 'user dependent' meaning that
each user is required to train their voice on the system, or
enroll through training so that the computer recognizes their
own specific, unique speech patterns, pronunciations and
intonations. Programs normally provide a large built-in
vocabulary which can be modified and developed further depending
on each individual users speech patterns, frequently used words
and language. Dragon Systems and IBM are two companies that have led in the research and development of products that support speech recognition.
