Cepstral david crack1/15/2024 ![]() In a meta-analysis on the validity of single acoustic markers in measuring overall voice quality, Maryn et al. ![]() With the PHONANIUM script for analyzing voice/speech sounds with cepstral methods and measuring various quefrency-domain voice markers in the program Praat, all relevant aspects and statistics can easily be obtained for different voice/speech tasks.ĭescription Sound cepstrography and quefrency-domain analyses v.01.02 Therefore, cepstral analysis of voice sounds has become a conditio sine qua non in clinical voice assessment. (2014)– the cepstrum with its related analysis techniques and markers has proven to be a feasible, valid and robust domain for measuring voice quality/dysphonia severity. (1994) and Hillenbrand & Houde (1996), up to more recently with for example Heman-Ackah et al. Based on an impressive multitude of studies so far –starting with Hillenbrand et al. ![]() 2631)” and “This cepstral metric thus can be regarded as the most promising and perhaps robust acoustic measure of dysphonia severity. (2009) wrote “Collectively, measures derived from the cepstrum (such as cepstral peak prominence and smoothed cepstral peak prominence) can be used in sustained vowel as well as continuous speech samples because they do not rely on accurate fundamental period detection, and they can be easily implemented in clinical settings. ![]()
