Abstract:
An autocorrelation calculating part calculates autocorrelation R o (i) from an input signal. A predictive coefficient calculating part performs linear predictive analysis using modified autocorrelation R′ o (i) obtained by multiplying the autocorrelation R o (i) by a coefficient w o (i). Here, a case is comprised where, for at least part of each order i, the coefficient w o (i) corresponding to each order i monotonically decreases as a value having positive correlation with a pitch gain in an input signal of a current frame or a past frame increases.

Claim (Index 5):
A non-transitory computer readable recording medium in which a program causing a computer to execute each step of the linear predictive analysis method according to  claim 1  or  2  is recorded.
