ESTIMATING A PITCH LAG

摘要

An electronic device for estimating a pitch lag is described. The electronic device includes a processor and executable instructions stored in memory that is in electronic communication with the processor. The electronic device obtains a current frame. The electronic device also obtains a residual signal based on the current frame. The electronic device additionally determines a set of peak locations based on the residual signal. Furthermore, the electronic device obtains a set of pitch lag candidates based on the set of peak locations. The electronic device also estimates a pitch lag based on the set of pitch lag candidates.
