How to take the Fourier transform of a speech signal?

Hi Guys!

Good Morning/Evening Whenever you guys are reading this.

I have a problem i am new into MATLAB, So Please guide accordingly.

i have an audio file of a male voice(only voice not music) and i want to take the fourier transform of this speech file.

after that i want this to plot on a graph.

once done the above i want to know the bandwidth of this signal?

after that i just want to plot the fourier data of the speech signal to display as histogram ?

Please guide.

Thanks

See the documentation on the fft (link) and spectrogram (link) functions.
