Speech processing is the study of speech signals and the processing methods of these signals.

Speech processing is the study of speech signals and the processing methods of these signals. The signals are usually processed in a digital representation, so speech processing can be regarded as a special case of digital signal processing, applied to speech signal.

Speech signal is one form of audio signal. The others are tone, music and noises. A method in signal processing usually tested with music, speech and mixture of both to test the developed algorithm.

What is the unit of x-axis of a sound signal?

I'm confused about the unit of x-axis. The below signal has a duration of 3 second and sampling frequency 44100. So should i write Time(s) for the unit of x-axis. However, in the graph, it shows the number of samples i.e 44100 * 3 = 132300.
