The vocal quality of a patient is modeled by means of a Dysphonia Severity Index (DSI), which is designed to establish an objective and quantitative correlate of the perceived vocal quality. The DSI is based on the weighted combination of the following selected set of voice measurements: highest frequency (F(0)-High in Hz), lowest intensity (I-Low in dB),(More)
The perceptual GRBAS scale for deviant voice quality (completed with a "I" parameter: Instability = fluctuation of voice quality over time) was tested in 5 different institutes on 943 voice patients. Each voice was evaluated separately by 2 professionals. The interrater correlation reaches 0.87 for G (grade), 0.70 for R (roughness), 0.69 for B (breathiness)(More)
Recurrent respiratory papillomatosis (RRP) is caused by a human papilloma virus (HPV). It is a rare, sometimes debilitating disease compromising voice and airway. RRP is characterized by a variable course of disease, potentially leading to frequent annual surgical procedures, the number of which may exceed a hundred during the life time. The therapy focuses(More)
The perceptual GIRBAS scale for deviant voice quality was tested in 5 different institutes on 943 voice patients. Each voice was evaluated separately by 2 professionals. The interrater and intrarater correlation is satisfactory for G, R and B. Experience with the scale significantly improves the interrater agreement. Further, GIRBAS/acoustical correlations(More)
The aim of this study is to establish relevant objective parameters for evaluating dysphonia following unilateral vocal fold paralysis. To do so, the study compares objective and perceptual voice measures. The objective measures were obtained using a voice analysis software (Evaluation Vocale Assistée), whereas the perceptual measures were established with(More)
The purpose of this study is to examine the most reliable and valid way for rating and comparing videolaryngostroboscopic recordings with a differentiated protocol. 30 high quality videostroboscopic recordings (2-5 minutes) of all kinds of vocal fold pathology were rated independently by 7 experienced laryngologists/phoniatricians, using a standardized and(More)
After total laryngectomy, the placement of a tracheoesophageal (TE) puncture offers the possibility to gain a new voice. However, the produced TE speech is known to have a lower quality and intelligibility. The goal of this paper is to identify and quantify the acoustic artefacts in TE speech. The advantage of this study is twofold. First, the proposed(More)
The Phonosurgery Committee of the European Laryngological Society (ELS) has examined the definition and technical description of phonosurgical procedures. Based on this review, the committee has proposed a working classification. The current presentation is restricted to vocal fold surgery (VFS) with phonosurgical intent. Both the pathology and the(More)
