Effects of bandwidth on glottal airflow waveforms estimated by inverse filtering
P Alku, E Vilkman - The Journal of the Acoustical Society of America, 1995 - pubs.aip.org
The aim of this research was to examine the effect of the bandwidth on parameters that are
used to quantify glottal airflow waveforms that have been obtained by inverse filtering the
acoustic signals. Three bandwidths (1, 2, and 4 kHz) were compared using/a/vowels of
different phonation types. Glottal waveforms were characterized using three ratios computed
from the flow (open quotient, speed quotient, and closing quotient) and two parameters
extracted from the differentiated flow (the amplitude of the negative peak and the return time …
