What is speech preprocessing?
Abstract: Speech signal preprocessing is the first and the most important step in the automatic speech recognition process. The preprocessing of speech consists of cleaning the speech signal from ambient and undesirable noises, detecting speech activity, and normalizing the length of the vocal tract.
What is speech processing in multimedia?
Speech processing is the study of speech signals and the processing methods of signals. The signals are usually processed in a digital representation, so speech processing can be regarded as a special case of digital signal processing, applied to speech signals.
What is the use of speech processing?
Purpose of speech processing: – To understand speech as a means of communication; – To represent speech for transmission and reproduction; – To analyze speech for automatic recognition and extraction of information – To discover some physiological characteristics of the talker.
How is a speech processed?
Speech, then, is produced by an air stream from the lungs, which goes through the trachea and the oral and nasal cavities. It involves four processes: Initiation, phonation, oro-nasal process and articulation. The initiation process is the moment when the air is expelled from the lungs.
