Summary :
Objectives: Evaluation of a perceptual specific rating scale for specific severe non laryngeral dysphonia. Material and method: 113 speech samples from substitution voices were scored perceptually according to the IINFVo scale: overall quality impression (I), impression of Intelligibility (I), additive and unnecessary noise (N), speech fluency (F) and presence of voiced segments (Vo). Each parameter was scored on a visual analogue scale from 0 (minimally deviant) to 10 (maximally deviant substitution voicing). These samples were presented to semi-professional jury-members (second grade speech therapy students) and professional jury-members (phoniatricians and speech therapists, specialised in the oncological field). Results: Interindividual agreement between semi-professionals was moderate (0.57-0.68). Interindividual agreement between professionals was higher (0.82-0.86). These figures are similar or even better compared to the classical perceptual evaluation scale for laryngeal speech (GRBAS). Conclusion: Our study suggests that the I(I)NFVo rating scale is suitable for perceptual evaluation of substitution voicing and consistency results are comparable with the classical perceptual rating scale (GRBAS).
