Figure 8.18: Close-up of waveform of the possible word == == == == (Speaker K)
Figures 8.19 and 8.20 show close-up views of the closure period for the words
= = = = ‘spirit’ and AA AA AA AA ‘who’. Both of these tokens exhibit a large, level signal amplitude
during closure rather than a rising amplitude. Here we see that in addition to the main
pulses occurring at the period of the fundamental frequency, there are also intermittent
smaller pulses of about half to two-thirds the amplitude of the main pulses. This is similar
to the biphasic pattern which Ladefoged & Maddieson claim corresponds to
laryngealization (cf. their Figure 3.3, p. 54).
