Figure 4

Means and standard errors for the perception experiment. For the EP listeners (top panels) and the Italian listeners (bottom panels). Shown are the percentages of /ɡ/ responses (y-axis) over all listeners with respect to the factor voicing maintenance (in percent of the stop closure duration, x-axis). The three panels split the data by vowel duration (from left to right, 70, 100 and 130 ms, respectively) and within each panel the different lines correspond to the three stop durations (100, 125 and 150 ms, respectively).
