Field: Computer technology (Electrical engineering)
Classification: CPC G | IPC G

Claim 1:
2. The VAD device of claim 1, wherein a first energy variation value of the X energy variation value(s) is generated by comparing a first energy correlation value of the X energy correlation value(s) with the energy threshold; when the first energy correlation value is greater than the energy threshold, the first energy variation value is set to be indicative of a wide energy variation; when the first energy correlation value is not greater than the energy threshold, the first energy variation value is set to be indicative of a slight energy variation; and the wide energy variation is in favor of an energy-based VAD algorithm of the multiple VAD algorithms while the slight energy variation is in favor of a pitch-based VAD algorithm of the multiple VAD algorithms.
