Voice is a analog signal. Computer is working digitally. during digital conversion to know the quality of conversion we uses Sampling frequency. If the sampling frequency is high, the quality of audio will be Good. The audio file size also high. If the sampling frequency is low, audio quality is also low and file size is also small. CD is using sampling frequency 41 kHz
means audio quality will be good. Telephone sampling rate is 8 kHz means audio quality will be poor.

for voice normally used in telephone - bandwidth of the voice is 4KHz and so sampling frequency is 8KHz.
or sampling frequency is normally double of BW of signal.

Standard CD sampling freequency is 44.1KhZ (44100Hz). I usually record voice at that frequency.
