Spectrogram using short-time Fourier transform - MATLAB ...
https://la.mathworks.com/help/signal/ref/spectrogram.html
s = spectrogram (x) returns the short-time Fourier transform of the input signal, x . Each column of s contains an estimate of the short-term, time-localized frequency content of x. s = spectrogram (x,window) uses window to divide the signal into segments and perform windowing. example. s = spectrogram (x,window,noverlap) uses noverlap samples ...

2015-6-25 · The sound spectrogram is one of the most fundamental tools of digital speech processing. The sound spectrogram of a speech file is an image map of the sequence of short-time log (or linear) spectrums, where each spectrum is obtained from an STFT analysis of a frame of speech, and subsequent spectrums are obtained from STFT analyses of subsequent, highly …
