Abstract [en]

The audio signal from five professional operatic baritone singers was analysed by means of spectrum analysis. Each subject sang a sustained diminuendo, from loudest to softest phonation, three times on the vowels [a:] and [ä:] at fundamental frequencies representing 25%, 50% and 75% of his total pitch range as measured in semitones. During the diminuendi the subjects repeatedly inserted the consonant [p] so that associated subglottal pressures could be estimated from the oral pressure during [p]­occlusions. Pooling the three takes of each condition, ten subglottal pressures (PS), equidistantly spaced between highest and lowest, were selected for analysis along with the corresponding production of [a:] and [ä:] vowels. The levels of the first formant and the singer’s formant, L1 and LSF, were measured as a function of increasing subglottal pressure. Averaged across subjects, an increase in PS resulted in (a) an increase in L1 and (b) a decrease in L1-LSF. This implies that a 10 dB increase at or near 600 Hz was, on average, accompanied by an increase of 17 dB of the level near 3 kHz.
