Design of Simulator for Automatic Voice Signal Detection and Compression ( AVSDC )

10  Abstract—A good amount of work has been done in the field of compression, voice signal detection, and spectrum analysis which has been generated a number of results in the past few decades. In this research, following three important problems have been identified: 1. To distinguish between constitutional and unconstitutional Voice: It is an important task to identify authenticity of recorded voice of the specific person. Here it has been tried to develop a Simulator which identifies constitutional and unconstitutional voice. 2. To identify words sequence:It is an important task to recognize words sequence in the recorded voice. Sometimes voice may be recorded fast, clear, or loud. Here it has been tried to develop a simulator to checkout whether recorded words are in proper sequence are not. 3. To develop a simulator which does not change file extension and quality of voice signal after compression: Normally, after compression, file extension is changed and quality of the voice signal is deteriorated. Here it has been tried not to change extension of the file after compression with minor distortion in voice signal. As per review of above three problems, it is being considered a simulator may be designed which may resolve above problems. With this view, the research title is chosen as “Design of Simulator for Automatic Voice Signal Detection and Compression (AVSDC)” which is suitable for pervasive computing, voice signal detection, and spectrum analysis. AVSDC is divided into following two parts: 1. Automatic Voice Signal Detection (AVSD) 2. Automatic Voice Signal Compression (AVSC)
