- The paper deals with the conversion of masculine voice of transgender to feminine voice. This conversion of voice is carried out by manipulating the two major acoustic features of speech signal. The two acoustic features here are the frequency and pitch. Frequency is a physical quantity which gives number of vibrations per second whereas pitch is a perceptual quantity which depends upon the listener. In fact our ears detects the pitch not the frequency. The phase 1 of the paper, software execution was carried out in the MATLAB software. The first step would be obtaining the input signals. The input signal is a recorded audio signal in the .wav format. Next step is to analyse and detect the pitch of the input speech signal. The pitch analysis is done by the auto-correlation method. The low pass filter is used to get rid of the high frequency noise signal in the form of impulse. Then the input signal decomposed into number of windows depending upon the total length of the signal. The decomposition and overlapping of the signal is the PSOLA method. By using the PSOLA method we increase the frequency of the input signal to get the desired output signal. The overlapping of signal increases the frequency of the speech signal. Thus the desired output is generated by manipulating the recorded input signal. The hardware execution part has a lots to do with the real-time implementation of the paper. The hardware is required to obtain the input signal in real-time and give out the output in real time with a small delay. Here in this paper the input signal the raspberry pi 4 model B is used to obtain the input through a microphone and give out the output through the Bluetooth speaker. The raspberry pi 4 model B follows the stand-alone execution , to give out the desired output in real-time.
