abstract = "Fundamental frequency (F0) extraction in disordered voice is a prerequisite for many types of clinical analyses. In this paper, we make an approach to F0 extraction based on audio waveform modeling and evaluate it with regard to reference F0s obtained from laryngeal high-speed videos. We analyze 65 euphonic and 112 dysphonic (28 diplophonic, 84 non-diplophonic) intervals of sustained phonations during rigid telescopic high-speed video laryngoscopy. Waveform modeling has a total error rate ETotal of 46.28 % on diplophonic voices, which is a significant improvement compared to a benchmark method (95.74 %). The results illustrate that F0 extraction in diplophonic voice is challenging. Multiple F0s need to be considered in the analysis of disordered voice, which may lead towards more valid clinical voice assessment in the future.",
