The voice fundamental frequency statistical parameters under noisy conditions with the cepstrum method
Jovan Galić, Tatjana Pesic-Brdanin · 2011
An influence of white noise on basic statistical parameters (the mean, the standard deviation, the median and the mode) of the speech signal fundamental frequency is analyzed in this paper. Fundamental frequency determination is done using MATLAB software, with the cepstrum method. It is shown that the median can be used as the best estimator of the fundamental frequency.
