This paper presents a method for identifying tonal signal parameters using zero crossing detection. The signal parameters: frequency, amplitude and phase can change slowly in time. The described method allows to obtain accurate detection using possib

This article presents a method for eliminating tonal components from acoustic signals. Tonal components are quasi-periodic signals whose amplitude, frequency and phase can change slowly with either a certain tendency or randomly. Active elimination o

For some time, new methods based on a different than acoustic signal analysis are used for speech recognition. The purpose of nonacoustic signals is to allow silent communi‐ cation. One of these methods based on the electromyography signal is gener
