Figure 5.5: Spectrogram of the sequence /ibE/ from "Liebe" (love), speaker sp126, sentence
reading task. Left cursor positioned at vowel offset, right cursor at vowel onset,
respective formant frequency values can be read from the panel below. Bottom
panel: waveform window, next panel from bottom: spectrogram window, left upper
panel: waveform zoom window, right upper panel: amplitude spectrum window.
The next interpretable event is the burst spectrum, which reflects the configuration of
the vocal tract at the point of the release. In case of a bilabial occlusion, the lingual
configuration of the vowel following the plosive is finished and, consequently, the
spectrum of the plosive reflects this configuration. In Figure 5.5 the vowel following the
plosive is [E] and, consequently, a spectral peak can be observed in the region of the F2
of [E] (about 1560 Hz). In Figure 5.6, the following vowel is [Ç] and, consequently, a
spectral peak can be observed in the region of F2 of the a-schwa, namely about 1340
Hz.
Figure 5.6: Spectrogram of the sequence /ibÇ/ from "lieber" (like something better), speaker
sp126, from a repeating sentences task. Left cursor positioned at vowel offset, right
cursor at vowel onset. Respective formant frequency values can be read from the
panel below. Bottom panel: waveform window, next panel from bottom:
