One of the most established pillar systems includes the following 5 pillars/facets as a minimal standard for voice assessment: a visual analysis of the vocal folds and the larynx, an auditory-perceptual judgment, an aerodynamic analysis, an acoustic analysis, and a self-assessment (Dejonckere et al. 2001; Boominathan et al. 2014; Lechien et al. 2023). Such a multidimensional voice protocol should be quantifiable for all individual measurement parameters, enabling a more effective assessment, for example, before and after treatment. Sections 2.1 to 2.5 list and describe various measurement parameters under this successfully evaluated five-pillar system, considering the current state of research, evidence, and technology. They are handled as a minimal standard to evaluate voice problems and voice disorders for the individual patient, as well as to determine the extent to which dysphonia (degree of dysphonia severity) is present due to the deviant measurement parameters.
