Shadrina G. Speech signal mathematical model for biotechnical system of speaking abilities reabilitation

The objekt of investigation is speech signal. The aim of the work is to develop methods and technique of speech signal mathematical modelling for feedback in biotechnical system of speaking abilities reabilitation. The adequacy of the speech signal mathematical model in the form of periodically correlated random process is grounded (for vowels). It is found that the suggested speech signal model gives the possibility to build the sample visual image. The construction of the reabilitation system structural scheme is reasoned and its stability conditions are defined. The main results of the work are applied into the speech correction of the deaf children and while investigating of speech deflexion. The area of application - speaking abilities reabilitation, futher speech signals researches.
