Quantitative measurement of speech sound distortions with the aid of minimum variance spectral estimation method for dentistry use

Abstract

In this paper, we search an adequate quantitative method based on minimum variance spectral analysis in order to reflect the dependence of the speech quality on the correct positioning of the dental prostheses. We also search some quantitative parameters, which reflect the correct position of dental prostheses in a sensitive manner.

Mechanical Properties of the Periodontal System and of Dental Constructs Deduced from the Free Response of the Tooth

“…As pointed out above, there are two ways to describe the properties of this deformable solid, each with a corresponding set of parameters which expresses the physical properties of the system investigated: with more precise rheological models or with a simplified description of these properties with discrete mechanical models with n DOFs. This latter type of investigation which we utilize in this study is employed in the modal analysis of vibrating systems or in mechanical systems identification [ 28 , 29 ].…”

“…The modal analysis/structural dynamics provides a series of methods (in time or in the frequency domain) that are able to extract the relevant information concerning the properties of the physical system from the experimental results [ 28 , 29 ]. In the presence of noise or of a reduced number of measured values, nonparametric methods like the autoregressive or the minimum variance method have to be utilized [ 27 , 30 ].…”
