Syllable numbers vary from 50 to 200 in a phrase (Fig. 15 C). The duration of syllables generally changes between 215 and 235 ms (Fig. 15 D). A syllable starts with lower amplitude pulse at the beginning of the syllable and continues with 7–9 observable high amplitude pulses in the remaining part (Fig. 15 D).
