The correct answer is: A. continuous speech recognition
Continuous speech recognition is a type of speech recognition that can handle continuous speech, i.e. speech that is not broken up into words or phrases. This is in contrast to isolated word recognition, which can only handle speech that is spoken one word at a time.
Continuous speech recognition is more difficult than isolated word recognition because it has to deal with the problem of coarticulation, which is the phenomenon where the pronunciation of one sound is affected by the sounds that come before and after it. For example, the “t” sound in the word “butter” is pronounced differently than the “t” sound in the word “top” because of the influence of the “u” sound that comes before it.
Continuous speech recognition systems typically use a technique called dynamic time warping
