Congratulations to Olivia Murton for getting another publication under her belt! Her forthcoming paper is titled, "Cepstral peak prominence values for clinical voice evaluation." It will be published in the American Journal of Speech-Language Pathology.
The goal of this study was to employ frequently used analysis methods and tasks to identify values for cepstral peak prominence (CPP) that can aid clinical voice evaluation. The CPP cutoff values identified in Experiment 1 provide normative reference points for clinical voice evaluation based on sustained /a/ vowels and the Rainbow Passage. Experiment 2 provides an initial predictive framework that can be used to relate CPP values to the auditory perception of overall dysphonia severity based on sustained /a/ vowels and CAPE-V sentences.
