FIELD: medicine.
SUBSTANCE: audiometry is performed; an acoustic frequency-response characteristic is evaluated, and a frequency range of residual perceptive hearing sensitivity is recovered. A base of visual images sounded by respective reference voice signals is formed. A visual image is selected in the data base; its image and its letter symbol are represented and simultaneously sounded. Before supplied to the patient, the respective reference voice signal is transformed by translating its spectrum into the frequency range of the patient's residual perceptive hearing sensitivity and supplied to the acoustic organs. The patient's responses are analysed by comparing the signal from the patient after representing the reference voice signal with the respective reference voice signal; a coincidence rate to be visually presented in the form of a numerical correlation showing the patient's correct pronunciation is assessed. The method is implemented by using a device comprising a microphone, an electronic circuit board and headphones. The electronic circuit board is designed to form the data base to store the tutorial images and audio files, displaying the tutorial images, and provided with a computer input connector.
EFFECT: invention enables reducing the length of audio-verbal rehabilitation that is ensured by forming noise-immune and invariant voice signal identification, objective assessment of the patient's ability to percept speech in the process of rehabilitation.
