Explanation / Answer

Consonant 'z' is at the begning of this waveform.

Aperiodic hissing of fricative ‘z’ is produced by constricting the air flow to produce turbulence. The waveform of voiced ‘z’ reveals that the pattern of the large peaks is quite periodic. The pattern of the fine detail is, on the other hand, a mixture of periodic or repeating features and aperiodic or non-repeating features.
