Development and Implementation of PC-based Acoustic Analytic Procedures for the Clinical Diagnosis of Neurogenic Speech Defects (Entwicklung und implementierung pc-gestuetzter akustischer analyseverfahren fuer die klinische diagnostik neurogener sprechstoerungen)

摘要

Approximately two percent of the population suffers from brain damage. Some of these cases lead to speech defects. The diagnosis of neurogenic speech defects is a speciality of clinical neuropsychology. The typical approach is subjective. Technical acoustic evaluation procedures are rarely used in diagnosis and therapy. This dissertation describes a 'modular diagnostic system for speech defects' that supports the standard diagnosis of neurogenic speech defects based on the acoustic analysis of the speech signal and the compilation of diagnostic parameters.
