Detect boundaries of speech in audio signal - MATLAB ...

    https://www.mathworks.com/help/audio/ref/detectspeech.html
    Depending on your application, you might want to extract spectral entropy from only the regions of speech. The resulting statistics are more characteristic of the speaker and less characteristic of the channel. Call detectSpeech on the audio signal and then create a new signal that contains only the regions of detected speech.

    To better understand the audio signal, it is necessary to transform it into the frequency-domain. The frequency-domain representation of a signal tells us what different frequencies are present in the signal. Fourier Transform is a mathematical concept that can convert a continuous signal from time-domain to frequency-domain. Let’s learn more ...
