Abstract

When the soprano raises the fundamental frequency above the first formant of a vowel, a remarkable loss of acoustic energy and linguistic information occurs along with an abrupt change in the voice timbre. To avoid these effects, sopranos are assumed to tune their first formant to the raised fundamental frequency. The support for this claim is mostly based on formant data provided by indirect measurement methods and articulatory data, since direct acoustic data becomes more difficult (or even impossible) to obtain as the fundamental frequency gets higher. In the present study a new combination of measurement methods is introduced. The aim was to extract formant data of three sopranos in the entire set of the Hungarian vowel inventory in a wide pitch range. The results provide evidence for the technique of tuning the first formant to the raised high fundamental frequency in a substantial amount of data.
