Table 4. The calculations for time intervals (a) between airflow peak and glottal opening onset (T_GOO), (b) between airflow peak and glottal opening peak (T_GOP) and (c) between vowel onset and airflow peak (T_ASP).

(a) TGOO = time at airflow peak (tFWP) – time at glottal opening onset (tGOO)

(b) TGOP = time at airflow peak (tFWP) – time at glottal opening peak (tGOP)

(c) TASP = time at vowel onset (tVO) – time at airflow peak (tFWP)
