15th International Congress of Phonetic Sciences (ICPhS-15)
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.
