Hello, i am working on analysis of baby cry signal. fundamental frequency(Fo) of signal is already estimated using auto correlation and cepstrum analysis. cry signal is inputted in .wav format. now i want to do short time fourier transform analysis of same signal inorder to find variations in fundamental frequency over the time and plot its "pitch contour". i.e. Fo v/s t. its like finding Fo value for each small interval and plotting over time to see the variability. pls, can anybody help me with the matlab code? image is uploaded for reference.
