- Description: Six male music theatre singers were recorded in three different voice qualities: legit and two types of belt ("chesty" and "twangy"), on two vowels ([e] and [O]), at four increasing pitches in the upper limit of each singer's belt range (similar to 250-440 Hz). The audio signal, the electroglottographic (EGG) signal, and the vocal tract impedance were all measured simultaneously. Voice samples were analyzed and then evaluated perceptually by 16 expert listeners. The three qualities were produced with significant differences at the physiological, acoustical, and perceptual levels: Singers produced belt qualities with a higher EGG contact quotient (CQ(EGG)) and greater contacting speed quotient (Qcs), greater sound pressure level (SPL), and energy above 1 kHz (alpha ratio), and with higher frequencies of the first two vocal tract resonances (f(R1), f(R2)), especially in the upper pitch range when compared to legit. Singers produced the chesty belt quality with higher CQ(EGG), Qcs, and SPL values and lower alpha ratios over the whole belt range, and with higher f(R1) at the higher pitch range when compared to twangy belt. Consistent tuning of f(R1) to the second voice harmonic (2f(0)) was observed in all three qualities and for both vowels. Expert listeners tended to identify all qualities based on the same acoustical and physiological variations as those observed in the singers' intended qualities.

- Description: Three Music Theater vocal qualities (“chesty belt,” “twangy belt,” and “legit”) were investigated in female singers at their overlap range, between F#4-D5 (∼370-600 Hz). Six experienced Music Theater singers performed each quality on two different vowels ([e], [ɔ]). Audio and electroglottographic (EGG) signals were recorded as well as the vocal tract impedance. In chesty belt and twangy belt, singers systematically tuned the frequency of their first vocal tractresonance (R1) to the second harmonic (2f0 ) up to C5. R1 remained lower in frequency for the legit quality. No tuning of the second vocal tractresonance (R2) was observed in any of these qualities although R2 frequency was significantly higher in both belt qualities than in legit. Closed quotient, degree of symmetry of the EGG waveform, sound pressure level (SPL) and the energy of the spectrum above 1 kHz were significantly greater in chesty belt than in legit but not significantly different between chesty belt and twangy belt qualities. A fourth quality (“mix”) was explored in three singers. Different production strategies were observed for each singer, with values of spectral, glottal and vocal tract descriptors found in between those measured for legit and chesty belt qualities.
