Kindly tell me, how I can save the spectrogram without any labels, ticks or surrounding frame area as a JPEG image in my hard drive?

Method # 2 of
and
saveas(gcf,'filename.png')
Although the above link was for part of spectrogram, but I applied it for the full spectrogram.
But it is saving the x and yaxis along with numbers over them and the frame itself.

You can do the work yourself (as the axes contains a Position property from which you can determine what you need to crop), but the export_fig function from Yair Altman is probably what you need.
It should be able to export a screenshot of only the axes itself.
Otherwise, you could try digging in the properties to see if there is a CData property you could export directly (which would be the raw underlying data).
