1. A voice data processing method comprising:

  • a first step of, in a normal mode, decoding input signal data, repeating a calculation in coarse search used for a pitch detection by a predetermined frequency of loops within a required frequency of loops, based on history decode data, and holding a peak value of a normalized cross-correlation obtained by the calculation and a delay data value corresponding thereto; and

    a second step of, in a packet loss mode, executing the pitch detection by repeating a calculation of a normalized cross-correlation in the coarse search by a remaining required frequency of loops, by using the peak value of the normalized cross-correlation and the delay data value, thereby generating compensating data.
