摘要：
As pitch enhancement processing, a pitch enhancement apparatus obtains, for a time segment judged to be a time segment including a signal that is a consonant, for each time of the time segment, as an output signal, a signal including a signal obtained by adding a signal, which was obtained by multiplying a signal at a time that is an earlier time than the time by the number of samples T0 corresponding to a pitch period of the time segment, the pitch gain σ0 of the time segment, a predetermined constant B0, and a value that is greater than 0 and less than 1, and a signal at the time.
