This study examines electroglottographic (EGG) recordings for 15 young and 14 old male speakers of New Zealand English. Analysis was performed on the sustained vowels /i:/ and /a:/ at three target levels for both pitch and loudness. Jitter was greater for older speakers, and the contact quotient (Qx) was significantly lower for older speakers. The greater jitter for older speakers indicates a decrease in the stability of the vocal production mechanism of the older speakers. The jitter is an… CONTINUE READING
