چکیده

A growing body of contemporary research has investigated differences between trained and untrained singing voices. However, few studies have separated untrained singers into those who do and do not express abilities related to singing talent, including accurate pitch control and production of a pleasant timbre (voice quality). This investigation studied measures of the singing power ratio (SPR), which is a quantitative measure of the resonant quality of the singing voice. SPR reflects the amplification or suppression in the vocal tract of the harmonics produced by the sound source. This measure was acquired from the voices of untrained talented and nontalented singers as a means to objectively investigate voice quality differences. Measures of SPR were acquired from vocal samples with fast Fourier transform (FFT) power spectra to analyze the amplitude level of the partials in the acoustic spectrum. Long-term average spectra (LTAS) were also analyzed. Results indicated significant differences in SPR between groups, which suggest that vocal tract resonance, and its effect on perceived vocal timbre or quality, may be an important variable related to the perception of singing talent. LTAS confirmed group differences in the tuning of vocal tract harmonics.

Breathing and Singing: Objective Characterization of Breathing Patterns in Classical Singers

Singing involves distinct respiratory kinematics (i.e. movements of rib cage and abdomen) to quiet breathing because of different demands on the respiratory system. Professional classical singers often advocate for the advantages of an active control of the abdomen on singing performance. This is presumed to prevent shortening of the diaphragm, elevate the rib cage, and thus promote efficient g...

Overlap of Hearing and Voicing Ranges in Singing.

Frequency and intensity ranges in voice production by trained and untrained singers were superimposed onto the average normal human hearing range. The vocal output for all subjects was shown both in Voice Range Profiles and Spectral Level Profiles. Trained singers took greater advantage of the dynamic range of the auditory system with harmonic energy (45% of the hearing range compared to 38% fo...

Subjective and Acoustical Data about Vocal Effectiveness in Western Opera: Preliminary Results

The notion of "vocal efficiency" is difficult to define. In order to contribute to this definition, several data were obtained: first the evaluation of glottal efficiency Eg using an acoustic analysis was obtained. Second, we run a study asking subjects to find synonyms of vocal effectiveness. Results showed the prevalence of the perceptual aspect over the communication and production aspects. ...

A Study of Vibrato Features to Control Singing Voices

Singing synthesis applications have recently been developed to create natural singing voices. Applications such as VOCALOID can synthesize singing voices by inputting lyrics and scores, and musical expressions such as vibrato and portamento are added to the singing voices by controlling pitches. This control is crucial to synthesize natural singing voices, but users are required to edit the pit...
