| Summary: |
Some time ago I asked a colleague to ask whether anybody knows literature on the influence of creaky voice on formant frequencies. I am working on speaker recognition and the reason, why I am interested in this question is that especially females, when they try to disguise their voice, use creak. During the production of creak it might be the case that the larynx is lowered (I personally do this), so this would create an effect on formant frequencies. The following references have been posted: Alexander Robertson Coupe recommended Ladefoged, Peter, Ian Maddieson and Michael T.T. Jackson (1988): "Investigation Phonation Types in Different Languages". In: Osamu Fujimura (ed.): Vocal Physiology: Voice Production, Mechanisms and Functions. Neww York: Raven, pp. 297-317. A possible effect of creaky voice on F1 is mentioned; the authors observed a slightly raised F1 in the creak vowel which they attributed to a raising of the larynx. Marc Picard and John Reighard suggested Peter Ladefoged and Ian Maddieson (1996): The sounds of the world's languages. Oxford: Blackwell. The section on phonation types is a summary of the 1988 paper. Anne T. Gilman recommended A. Batlinger et al. (1993): MUESLI: A Classification Scheme for Laryngalizations. In. D. House and P. Touati (ed.) .ESCA Prosody Worksop 1993, Working Papers, Lund, pp. 176-179. This is an excellent description of different types of laryngealizations, but unfortunately the effect on formant frequencies is not mentioned. She also recommended Olive, J.P., Greenwood, A. and Coleman, J.S. (1993): Acoustics of American English Speech, New York: Springer, which I have not yet looked at. Bart de Boer kindly sent measurements of creaky, modal and breathy vowels of his own voice, there was not much influence on formant frequencies. Helmer Strik expects no influences on formant frequencies, since creak is an expression of voice source which does not influence the vocal tract and its shape. Thanks to all who took the time to help Sylvia Moosmueller |
