15th International Congress of Phonetic Sciences (ICPhS-15)
The main goal of this study was investigating the voice quality of university teaching population, a group at risk of suffering from dysphonia. To evaluate the issue, a series of twelve parameters was established, from current studies in pathological voice and a previous pilot study: I) Phono-respiratory control; II) Proportion of maximum phonation time; III) [i] Jitter; IV) [a] Jitter ; V) [i] Shimmer; VI) [a] Shimmer; VII) Hoarseness; VIII) Breathiness; IX) Other alterations in vowel production; X) Alterations in F0 vowel range; XI) End of sentences without vocal cords vibration; XII) Other alterations in sentences. Each parameter was associated with a normal value, which allowed us to mark any production on a -/+ (=normal/abnormal) basis.
