Spectral Effects of Subglottal Cavity System
Gunnar Fant, K. Ishizaka, J. Lindqvist, Johan Sundberg · The Journal of the Acoustical Society of America · 1972
Aspirated sounds display shifts of formant frequencies and new formants are added. These can typically be observed in the aspirative part of stop consonant bursts. A quantitative modeling of this influence has been performed on the basis of subglottal impedance data and simple geometry approximations of the subglottal system. The influence of subglottal coupling on voice-source characteristics is discussed.
