FIGURE 9

The amplitude trajectories of Greek voiced stop lead and nasal murmur elicited at word initial position produced by six Greek-speaking adults (voiced stops (/d/) vs. nasals (/m/, /n/)). The abscissa represents the 6 proportional locations arranged chronologically (burst at the rightmost edge), and the ordinate represents the sound pressure normalized with reference to the following vowel amplitude. Zero at the ordinate corresponds to an amplitude equal to that of the following vowel. Each solid trajectory line shows the median values of the amplitude measured in the voiced stops and nasals across the glottal pulses prior to the burst. The dotted lines above and below the solid lines are 95% confidence interval lines.
