Voice quality
PHONETICS: Term referring to the permanently present quality of voice of a particular speaker. An individual’s voice quality is based on the combination of factors such as pitch level, loudness, tempo, timbre, breathiness, tenseness, nasality, hoarseness, etc.
Voice quality may also have a contrastive function in the phonological system of a language. Breathiness, for example, is phonemic for vowels in Gujarati and for stops in Igbo (Ladefoged & Maddieson, 1996)
