Estimation of Severity of Speech Disability through Speech Envelope

TL;DR

This study proposes a method to estimate speech disability severity in children aged five to eight by analyzing speech envelopes and applying ratio mean analysis to distinguish pathological cases.

Contribution

It introduces a novel envelope detection and ratio mean analysis technique for assessing speech disability severity in children.

Findings

Effective differentiation between pathological and normal speech signals.

Successful application of envelope analysis to estimate disability levels.

Potential for non-invasive, automated speech disability assessment.

Abstract

In this paper, envelope detection of speech is discussed to distinguish the pathological cases of speech disabled children. The speech signal samples of children of age between five to eight years are considered for the present study. These speech signals are digitized and are used to determine the speech envelope. The envelope is subjected to ratio mean analysis to estimate the disability. This analysis is conducted on ten speech signal samples which are related to both place of articulation and manner of articulation. Overall speech disability of a pathological subject is estimated based on the results of above analysis.
