Abstract: There are various ways of communication. Two people may communicate with each other through speech, gestures or graphical symbols. Man’s most natural way of communication is through speech. Though writing seems to be important means of communication and written words, appear to be more efficient means of transmitting intelligence, the amount of intelligence exchanged by speech is beyond comparison. Considering the importance of speech ,the speech analysis is carried out .Speech analysis is used in innovative way to find out parameters like Amplitude, frequency, energy and power, when throat gets infected because of viral infections or due to any other cause. Speech quality changes which changes the parameters. An experiment is carried out with the instrument DSO (Digital signal oscilloscope). Speech analysis of normal and infected throat that is performed without any treatment. The word “Hello” pronounced by 4 different persons in Normal health condition and when person when has infected throat. The main aim of this project is to compare signals of speech of normal throat person and infected throat person by analyzing Amplitude and frequency parameters which are obtained from DSO.The instrument set up consist of Input Module with Microphone (ST2108), DSO( Agilent Infiniti Vision 2000 X-Series oscilloscope). FFT software installed in computer for speech recording.
Keywords: DSO (Digital Storage Oscilloscope), FFT( Fast Fourier Transforms).
