Differentiated Objective Analysis of the Speech Quality of Chronically Hoarse Patients For differentiated diagnostics of functioning and evaluation of distorted voice (i.e. for chronic hoarseness), there are currently no validated objective approaches. Established methods evaluate voice quality only by processing sustained vowels. Important speech criteria, such as intelligibility, are not analyzed. This project served for the development of adequate methods in the context of a cross-sectional study with 87 adult patients. The first topic was modeling clinical evaluation criteria by objectively obtained parameters. The analysis is done text-based. Evaluation of speech quality is performed by automatic speech recognition, prosodic analysis, phonemic, and phonological features. The correlation between perceptual and automatic evaluation reached more than r=0.8.
Additionally, mathematical visualization methods, such as the Sammon Transform, allow for intuitive graphical depiction of the individual impairment and its extent. The second topic was the quantification of hoarseness which also includes speech-related parameters for the first time. In this way, an objective clinical evaluation is created.
The automatic analysis that has been developed in this project is the basis for future telemedical applications for the control of the progress of voice rehabilitation. Furthermore, this analysis will serve as objective addition to the established subjective voice and speech evaluation in clinical practice. The approach is another important step towards evidence-based diagnostics in Phoniatrics. | Project manager: Prof. Dr.-Ing. Michael Döllinger
