A method of the speech signal pitch frequency measurement for acoustic speech analysis systems
https://doi.org/10.32446/0368-1025it.2019-3-59-63
Abstract
In this paper we propose a novel method for measuring the pitch frequency of the increased noise immunity. The problem of protection against intensive background noise is solved in it by the frequency selection of vocalization pieces of a speech signal according to the scheme of the combfilter of inter-periodical accumulation. The efficiency of a new method is theoretically and experimentally examined using the specially developed multi-channel frequency measurement device for the acoustic speech analysis. It is shown that a measurement error in relative terms does not exceed 2 % for the 10 dB signal-to-noise ratio.
