The investigator uses a non-invasive methodology basedon a synchronous recording of voice, laryngographicsignal and subglottal resonance on 2 ‘European’overtone singers and 2 ‘Siberian’ semi-professionalthroat singers. For the upper registers of throat singing an extremely short contacting phase was obtained and SQseems 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
This book presents the first field-work based phonetic study focussing such extraordinary phonatory outcomes as occur in the context of South-Siberian throat singing. In throat singing specific voice production types serve as source, which are subject to various ways of formant shaping, merging, adjustment, and reinforcement, all of which function to enhance individual harmonics. Two main types are proposed for voice production in South-Siberian throat singing: a voice production by means of the vocal folds featuring a constriction of the aryepiglottic sphincter, and a voice production with involvement of the ventricular folds. Furthermore a simple schematic model for the articulation types in throat singing is suggested. One of the basic questions throughout this study is whether the phenomenon of throat singing shows fairly clear regional variants in different parts of southern or whether the variation is chiefly a matter of individual styles.
