L’Acoustic Voice Quality Index (AVQI) est un outil d’évaluation quantitative du degré général de la dysphonie. Son calcul comprend six paramètres acoustiques collectés via le logiciel gratuit Praat. Il est réalisé sur base des enregistrements d’une voyelle tenue ainsi que d’une partie d’un texte lu à voix haute. Les qualités psychométriques de cet outil ont été confirmées dans de nombreuses publications, et ce en plusieurs langues. Cependant, sa validation en français repose sur une petite cohorte de patients non francophones de naissance. De plus, la version 03.01 de l’AVQI n’a pas encore été validée sur un échantillon en français. Par conséquent, ce travail comporte trois étapes principales. D’abord, une phase préparatoire vise à identifier l’extrait optimal d’un texte français couramment utilisé en clinique journalière. Le second objectif est d’évaluer la validité critérielle ainsi que la précision diagnostique de l’AVQI 03.01 appliqué sur l’extrait identifié dans la phase préparatoire. Enfin, nous étudions la corrélation entre les scores AVQI et le handicap perçu par le patient, évalué à l’aide du VHI.
Ce travail nous permet entre autres d’inviter à la prudence dans l’utilisation de la technologie et de l’informatique pour l’évaluation vocale. À ce jour, l’évaluation à l’écoute par le thérapeute semble rester le seul outil permettant de percevoir dans sa totalité la réalité complexe et multidimensionnelle de la voix. The Acoustic Voice Quality Index (AVQI) is a tool for quantitative assessment of the overall severity of dysphonia. Its computation includes six acoustic parameters, which are all carried out by the freeware Praat. It is based on the recordings of a sustained vowel and a part of a text read aloud. The psychometric qualities of this tool have been confirmed by numerous publications in various languages. However, its validation in French relies on a small cohort of patients, who were not native French speakers. Furthermore, the version 03.01 of the AVQI has not yet been validated at all on a French sample. Hence, this work consists of three main stages. First a preparatory phase is intended to identify the optimal part of a commonly used French text to be used for the validation study. The second aim is to assess the criterion-related concurrent validity and the diagnostic accuracy of the AVQI 03.01 applied to this text extract. Eventually, we investigate the correlation between the AVQI scores and the handicap perceived by the patient, as assessed by the VHI. This work allows us to call for caution in the use of technology and computer science for vocal assessment. To date, the perceptual assessment by the clinician still seems to be the only way to catch the complex and multidimensional vocal reality in its entirety.

Special Issue “Advances in Management of Voice and Swallowing Disorders” is dedicated to innovations in screening and assessment and the effectiveness of interventions in both dysphonia and dysphagia. In contemporary practice, novel techniques have been introduced in diagnostics and rehabilitative interventions (e.g., machine learning, electrical stimulation). Similarly, advancements in methodological approaches to validate measures have been introduced (e.g., item response theory using Rasch analysis), prompting the need to develop new, robust measures for use in clinics and intervention studies. Against this backdrop, this Special Issue focuses on studies aiming to improve early diagnostics of laryngological disorders and its management. This issue also welcomes the submission of studies on diagnostic accuracy and psychometrics performance of existing and newly developed measures. This includes but is not limited to studies investigating screening tools with sound diagnostic accuracy and robust psychometric properties. Furthermore, interventions with high levels of evidence in relation to clinical outcome using robust methodology (e.g., sophisticated meta-analytic approaches) are of great interest. This issue provides an overview of the latest advances in voice and swallowing disorders.
