This paper proposes an approach to pitch-synchronous linear prediction (LP) for bone-conducted (BC) voiced speech. A combination of the spectral compensation (SC) method with pitch extension LP is used to obtain a more accurate power spectrum of the BC speech signal. Simulation experiments show that the proposed method provides better performance than the conventional autocorrelation and original SC methods.
