FIELD: medicine; logopedics.
SUBSTANCE: resonant frequency of the basic tone on the backbone length is defined where backbone is representing itself as the anatomic resonator. The computer analysis of the speech signal received by means of a microphone from the patient is carried out by its spectral analysis with definition of frequency, spectral density of power of the basic tone and the first overtone. Then practical lesson is conducted with use of a computer spectral analysis of the current speech signal received by means of a microphone from the patient, by monitoring of frequency, spectral density of power of the basic tone and the first overtone in the real time mode. Thus the patient by means of voice pitch and spectrum reorganisation carries out the task on deduction of basic tone real frequency on resonant frequency and the task on reduction of less value of spectral density of basic tone power than the first overtone value. Resonant frequency of the basic tone is defined under the formula λ=V/(K*L), where λ - frequency of the basic tone (Hz), V - sound velocity in environment - air (km/s), L - length of the backbone which is representing itself as the anatomic resonator (m), K - voice type factor, namely: K=21/3 - for very man's voice (deep bass); K=5/1 - for man's voices (bass); K=limit P(n+3)/R(n)=Phidias character cubed ˜4.236 (drama baritone); K=8/2 - for standard man's voices (baritone); K=3/1 - for a female voice (tenor, contralto); K=limit P(n+2)/R(n)=Phidias character in a square ˜2.618 (a drama mezzo-soprano); K=5/2 - for standard female voices (mezzo-soprano); K=2/1 - for high pitched female voices (soprano); K=limit P(n+1)/R(n)=Phidias character ˜1.618 (lyrical soprano); K=3/2 - for very high pitched female voice (coloratura soprano); K=1/1 - for the child.
EFFECT: maximum effective utilisation of sound output functional system at the minimum strain of vocal cords due to resonant sound output.
