Abstract:

Hypokinetická dysartrie (HD) je častým symptomem vyskytujícím se až u 90% pacientů trpících idiopatickou Parkinsonovou nemocí (PN), která výrazně přispívá k nepřirozenosti a nesrozumitelnosti řeči těchto pacientů. Hlavním cílem této disertační práce je prozkoumat možnosti použití kvantitativní paraklinické analýzy HD, s použitím parametrizace řeči, statistického zpracování a strojového učení, za účelem diagnózy a objektivního hodnocení PN. Tato práce dokazuje, že počítačová akustická analýza je schopná dostatečně popsat HD, speciálně tzv. dysprozodii, která se projevuje nedokonalou intonací a

Abstract:

This master´s thesis deals with the calculation of parameters that would be able to differentiate healthy speech and speech impaired by hypokinetic dysarthria. There was staged hypokinetic dysarthria, which is a motoric disorder of speech and vocal tract. Were studied speech signal processing methods. Further parameters were studied, which could well differentiate healthy and diseased speech. Subsequently, these parameters were programmed in Python programming language. The next step was to create a web application in Django framework, which is used for the analysis of the dyzartic speech.

Abstract:

This work deals with analysis of phonation in patients with Parkinson’s disease (PD). Approximately 90% of patients with Parkinson’s disease suffer from speech motor dysfunction called hypokinetic dysarthria. System for Parkinson’s disease analysis from speech signals is proposed and several types of features are examined. Czech Parkinson’s speech database called PARCZ is used for classification. This dataset consists of 84 PD patients and 49 healthy controls. Results are evaluated in two ways. Firstly, features are individually analysed by Spearman correlation, mutual information and Mann-Whi

This diploma thesis focuses on the automated diagnosis of hypokinetic dysarthria in the multilingual speech corpus, which is a motor speech disorder that occurs in patients with neurodegenerative diseases such as Parkinson’s disease. The automatic speech recognition approach to diagnosis is based on the acoustic analysis of speech and subsequent use of mathematical models. The popularity of this method is on the rise due to its objectivity and the possibility of working simultaneously on different languages. The aim of this work is to find out which acoustic parameters have high discriminative

För att uppnå en god omvårdnad av personer med talsvårigheter var det viktigt att individen fick känna sig sedd och hörd.

The aim of this diploma thesis is to identify, implement and test acoustic features of speech that could be used to objectify and automate the evaluation. These features should be easily interpretable by the clinician. It is assum

Perceptual learning, when applied to speech, describes experience-evoked adjustments to the cognitive-perceptual processes required for recognising spoken language. It provides the theoretical basis for improved understanding of a speech signal that is initially difficult to perceive. Reduced intelligibility is a frequent and debilitating symptom of dysarthria, a speech disorder associated with neurological disease or injury.

Despite this there are limited voice and speech treatments for this group of patients.

Background: Speech production in Bantu languages places great demands on neuromotor control, because unique speech motor behaviours such as syllabic tone variation and the aspiration of speech sounds require an additional level of vocal fold control compared to speech production in Germanic languages. As these motor behaviours play an important role in differentiating the meaning of words (Van der Merwe & Le Roux, 2014a), neuromotor speech disorders such as dysarthria may have a greater impact on communication in Bantu languages than in Germanic languages.

Abstract:

Purpose. The purpose of this study was to examine the influence of visual information on the intelligibility of dysarthric speech. The two research questions posed by this study were: (1) Does the presentation mode (auditory-only versus auditory-visual) influence the intelligibility of a homogeneous group of speakers with dysarthria? and (2) Does the experience of the listener (experienced versus inexperienced with dysarthric speech) influence the intelligibility scores of these speakers? Background. Investigations of speakers with hearing impairment and laryngectomy have indicated that intell

Abstract:

Dysarthria is a neurological speech impairment which usually results in the loss of motor speech control due to muscular atrophy and poor coordination of articulators. Dysarthric speech is more difficult to model with machine learning algorithms, due to inconsistencies in the acoustic signal and to limited amounts of training data. This study reports a new approach for the analysis and representation of dysarthric speech, and applies it to improve ASR performance. The Zeros of Z-Transform (ZZT) are investigated for dysarthric vowel segments. It shows evidence of a phase-based acoustic phenomen

Abstract:

Dysarthria describes the impaired speech intelligibility caused by weakness of muscles involved in speech following stroke. This is a common consequence of stroke and can have a detrimental impact on self-confidence leading to social isolation for many. There is limited evidence for dysarthria intervention but we know that research into speech difficulties after stroke is a priority for stroke survivors. An online speech rehabilitation programme was developed, ReaDySpeech, with the potential to offer improved quality of independent practice, increased intensity of practice and the ability to r
