Abstract
The paper analyzes the estimation of the fundamental frequency from the
real speech signal which is obtained by recording the speaker in the real
acoustic environment modeled by the MP3 method. The estimation was
performed by the Picking-Peaks algorithm with implemented parametric cubic
convolution (PCC) interpolation. The efficiency of PCC was tested for
Catmull-Rom, Greville, and Greville two- parametric kernel. Depending on
MSE, a window that gives optimal results was chosen.
