F0 and formant frequency distribution of dysarthric speech - a comparative study
نویسندگان
چکیده
We are investigating acoustical analysis for dysarthric speech, which appears as a symptom of neurologic disease, in order to elucidate its physiological and acoustical mechanism, and to develop aids for diagnosis and training, etc. In this report, acoustical characteristics of various kinds of dysarthrias are measured. As a result, shrinking of the F0 range as well as vowel space are observed in dysarthric speech. Also, from the comparison of F0 range and vowel formant frequencies it is suggested that speech effort to produce wider F0 range can influence vowel quality as well.

Speech Signal Analysis and Pattern Recognition in Diagnosis of Dysarthria
Background Dysarthria refers to a group of disorders resulting from disturbances in muscular control over the speech mechanism due to damage of central or peripheral nervous system. There is wide subjective variability in assessment of dysarthria between different clinicians. In our study, we tried to identify a pattern among types of dysarthria by acoustic analysis and to prevent intersubject ...
متن کاملAcoustic analysis of intonation in parkinson's disease
The aim of this study was to explore the prosodic characteristics of speakers with Parkinson’s disease (PD) in the marking of intonations. Twenty-four German PD speakers with either mild or moderate degree of dysarthria were compared with twelve non-dysarthric control speakers on the production of imperatives, questions and statements. Acoustic analyses of fundamental frequency (average F0, F0 ...
متن کاملEffects of frequency shifts on perceived naturalness and gender information in speech
In natural speech, there is a moderate correlation between the fundamental frequency and formant frequencies across talkers. The present study used a high-quality vocoder to manipulate these properties and determine their contribution to perceived naturalness and voice gender. The stimuli were re-synthesized sentences spoken by two adult males and two adult females. Scale factors were chosen fo...
متن کاملAnalysis of dysarthric speech by means of formant-to-area mapping
This article presents a preliminary study of dysarthric speech by means of formant-to-area mapping. Dysarthria is a speech impairment which is the result of paralysis or ataxia of the speech muscles. Formant-to-area mapping is the inference of the shape of a tract model via observed formant frequencies. The corpus is composed of vowelvowel sequences [iaia] produced by speakers su ering from amy...
متن کاملRecognition of Dysarthric Speech Using Voice Parameters for Speaker Adaptation and Multi-Taper Spectral Estimation
Dysarthria is a motor speech disorder resulting from impairment in muscles responsible for speech production, often characterized by slurred or slow speech resulting in low intelligibility. With speech based applications such as voice biometrics and personal assistants gaining popularity, automatic recognition of dysarthric speech becomes imperative as a step towards including people with dysar...
