Abstract This paper proposes a linear prediction method using the analytic signal which occupies half the bandwidth of the real signal. Consequently, the order is halved in the proposed method, thereby reducing drastically the computational complexity. The proposed method gives a stable solution for a finite word‐length operation, and the obtained reflection coefficient has a low coefficient sensitivity. These are both useful properties in the synthesis of speech.
