Speech Recognition is the decoding of human speech into transcribed text through a computer program. To recognize spoken words, the program must transcribe the incoming sound signal into a digitized representation, which must then be compared to an enormous database of digitized representations of spoken words. To transcribe speech with any tolerable degree of accuracy, users must speak each word independently, with a pause between each word and this substantially slows the speed of speech-recognition systems and calls their utility into question, With the exception in the case of physical disabilities that would prevent input by other means. See discrete speech recognition.
