TABLE II.

Statistical quantities computed from the current normal (symmetric) laryngeal model compared to typical ranges reported by previous studies. F₀ is the fundamental frequency; $Q_{\max }$ and $Q_{\text{mean}}$ are the peak and mean glottal flow rate, respectively; ${\tau }_0$ is the open quotient, defined as ${\tau }_0=T_0/T$, where $T_0$ is the duration of glottal open phase; ${\tau }_s$ is the skewness quotient, defined as ${\tau }_s=T_p/T_n$ where $T_p$ is the duration of the glottal acceleration phase and $T_n$ is the duration of the glottal deceleration phase.

	Computed	Typical
	Value	Range
$F_0$ ($\text{Hz}$)	243.5	65–260 (Zemlin, 1988)
$Q_{\max }$ ($\text{ml}/\mathrm{s}$)	299.65	200–580 (Hertegard et al., 1992)
$Q_{\text{mean}}$ ($\text{ml}/\mathrm{s}$)	147.55	110–220 (Zemlin, 1988)
${\tau }_0$	0.67	0.4–0.7 (Titze, 2000)
${\tau }_s$	1.19	1.1–3.4 (Ishizaka and Flanagan, 1972; Lamar et al., 2003; Duncan et al., 2006)
