Abstract
The investigator uses a non-invasive methodology based
on a synchronous recording of voice, laryngographic
signal and subglottal resonance on 2 ‘European’
overtone singers and 2 ‘Siberian’ semi-professional
throat singers. For the upper registers of throat singing an
extremely short contacting phase was obtained and SQ
seems to be appropriate to distinguish between both
phonation types. Lower registers share doublet and triplet
waveform patterns, but differ significantly in jitter and
shimmer rates (j < 0.1; sh < 0.15 for ThS). Other findings
are a narrowed bandwidth of a dominant F2 and an ostinato formant between F3 and F4, which are remarkable for all throat singing styles.
