A type of speech recognition
that is used to recognise isolated words, as compared to continuous speech recognition
. Although largely superseded, it is still used for some applications. For example, the algorithms are simple enough that some of the newer mobile phone
s can call a number that you say to them and this is done in hardware
; or sometimes automated call response systems make use of similar recognition systems when they give you a set of options to choose from.
Are usually implemented using either dynamic time warping or hidden Markov models.
