Formant Technique in a Professional Female Singer

Pitch-dependent changes in the lip and jaw opening are found in a professional soprano singer. The formant frequency shifts accompanying these articulatory changes are measured (1) by examining the responses of the vocal tract to an external excitation by means of a vibrator, and (2) by matching spectra of the sung vowels on a terminal analogue. With few exceptions these two methods gave similar results agreeing with the data collected on lip and jaw opening and on the intensity of the overall spectrum and the fundamental. It is found that the formant frequencies are similar to those of normal speech only when the fundamental is lower in frequency than the first formant. At higher pitches the first formant is found in the proximity of the fundamental. Also, the investigation appears to indicate that the acoustic theory of vowel production is applicable even to professional female singing.
