Figure 3.

Hypothetical events for high-frequency stop consonants ∕ta∕ and ∕da∕. The multiple panels in each subfigure are $\stackrel{⃞}{1}$ AI-gram. A dashed vertical line labels the onset of voicing (sonorance), indicating the start of the vowel. The solid and dashed boxes indicate the dominant and minor events, respectively. $\stackrel{⃞}{2}$ CPs as a function of truncation time t_n. $\stackrel{⃞}{3}$ CPs as a function of SNR_k. $\stackrel{⃞}{4}$ CPs as a function of cutoff frequency f_k. $\stackrel{⃞}{5}$ AI-grams of the consonant region (defined by the solid vertical lines on panel $\stackrel{⃞}{1}$) at −12, −6, 0, 6, 12, and 18 dB SNRs.
