“See what I mean, huh?” Evaluating Visual Inspection of F0 Tracking in Nasal Grunts
Résumé
This paper proposes to evaluate the method used in (Chlébowski and Ballier, 2020) for the annotation of F0 variations in nasal grunts. We discuss and test issues raised by this kind of approach exclusively based on visual inspection of the F0 tracking in Praat. Results tend to show that consistency in the annotation depends on acoustic features intrinsic to the grunts such as F0 slope and duration that are sensitive to display settings. We nonetheless acknowledge the potential benefits of such a method for automation and implementation in IA and in this respect, we introduce Prosogram as an alternative material-maker
