For speech signals, a common sampling rate used for digitization is 64 kHz. This rate is sufficient to capture the frequency range of human speech, which typically extends up to about 20 kHz, adhering to the Nyquist theorem that the sampling rate should be at least twice the highest frequency present in the signal.
