Computers and Speech Recognition: Techniques and Applications

Computers and Speech Recognition Techniques and ApplicationsAbstractSpeech is the most natural and coarse way of communication between people. It would seem only natural that information processing system development would eventually progress to the point where people would want to exit the human-computer interface to include reference. Once this happened, numerous proficiencys were explored. The goals of manner of speaking recognition became more than and more ambitious, and researchers today continue to push the limits of what computers can do with the mouth word. This paper examines the problem of computer speech recognition by look at the steps involved in getting from a verbalize word to the words recognition by the machine. The difficulties of continuous speech recognition leave behind be enumerated and examined, as will the most popular recognition technique used today. The analysis ends with a brief description of some of the applications of speech recognition.Intro ductionSimply put, speech recognition is difficult. A computer does not have a useful thing called an ear that enables it to hear sounds, or a brain to process those sounds into recognizable words and phrases. There atomic number 18 three main stages involved in speech recognition preprocessing, recognition, and communication. Preprocessing involves winning the speech input and converting it into something the computer can use. During the recognition stage, the computer mustiness identify what has been said. Finally, in the communication stage, the computer acts upon the translated input (Markowitz).There be legion(predicate) inherent difficulties involved in speech recognition. For example, human speech can span more than 20,000 frequencies. A computer would quickly change by reversal overwhelmed by data if it was supplied with eve... ...e applications where they could be useful. For many people in the sometime(prenominal) few years, speech recognition has moved from just b eing a novelty to becoming an important tool used in their free-and-easy lives.ReferencesBooks1.
