Linear-Prediction-Based Accurate Spectrum Estimation with Pitch Extension for Bone-Conducted Speech
Md. Arifour Rahman, Tetsuya Shimamura · Journal of Signal Processing · 2018
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.
