PROJECT: Evaluation of voice and speech disorders in dysarthria: EvalDy

The general aim of the project is to contribute to the characterisation and assessment of voice and speech disorders in dysarthria. The objective assessment (via acoustic and articulatory measurements) of pathological speech production is a rapidly expanding field of research, particularly in the French-speaking world, and there are many challenges to be met.

In the first phase, the project aims to document the speech production of a large number of French-speaking Belgian dysarthric patients, both men and women, with diverse profiles in terms of the type of dysarthria and associated aetiology (Parkinson's disease, Wilson's disease, Huntington's disease, Friedreich's ataxia, multiple sclerosis, amyotrophic lateral sclerosis, Kennedy's disease, dysarthria after stroke or head trauma) and the degree of severity of the dysarthria (mild, moderate, severe).

The acoustic recordings concern all the participants, who will be asked to produce the 8 modules of the MonPaGe 2.0.s protocol (repetition of pseudowords, intelligibility task, pneumo-phonatory module, reading of text, spontaneous speech, production of verbal diadocokinesis, automatic series and sentences with varied prosodic contours), to which 3 additional modules will be added (specifically targeting nasal phenomena, glides and phonetic flexibility skills). Several sub-groups of participants will be invited to carry out some of the modules in an experimental setting that will enable acoustic measurements to be combined with physiological measurements in order to study certain specific phenomena (acoustics and nasometry for nasality; acoustics, electroglottography and aerodynamics for coordination between the laryngeal and supra-laryngeal systems; acoustics and ultrasound imaging for articulatory precision; acoustics and imaging by nasofibroscopy and stroboscopy for voice quality).

Analysis of this large data set, in particular analysis of the relationships between acoustic and articulatory measurements, will aim to reduce the multiple acoustic measurements to a smaller number of reliable, robust indicators that can be used to characterise all the dimensions of dysarthric speech: laryngeal functioning, pneumo-phonatory behaviour (including intensity control), fluency, articulatory precision and gestural coordination, organisation of the vowel system, and aptitude for phonetic flexibility.

In a second phase, the project aims to use the acoustic indicators thus isolated to develop (i.e. design, operationalise, then assess the psychometric qualities and finally adapt) several assessment tools, each of which will be dedicated to meeting a more precise objective, defined either in relation to a research question or to a need identified in clinical practice.

The first objective concerns the sub-clinical signs of dysarthria in Parkinson's disease, and the possibility of using certain acoustic indices such as vocal biomarkers to assist clinicians in the early diagnosis of the disease. The second objective is to contribute to differential diagnosis, using a tool for acoustic assessment of speech production to distinguish between different subtypes of dysarthria, as well as between dysarthria and apraxia of speech. The third clinical objective concerns the temporal dynamics of the disease, viewed from an intra-individual perspective. The aim is to propose a tool that is suitable for longitudinal monitoring of dysarthric patients, once the diagnosis has been made. The fourth objective relates to a fundamental research question, that of characterising the evolution of dysarthria as a function of the degree of severity in the context of the retrogenesis hypothesis. The fifth objective concerns intelligibility. The aim is to produce a tool for assessing the intelligibility of dysarthric speech, which can be used in future work on the link between intelligibility, communicative efficiency and quality of life in dysarthric patients.
