CPPS and Voice-Source Parameters: Objective Analysis of the Singing Voice

The voice instrument is composed of three basic sub-systems: the pulmonary apparatus, the laryngeal voice source, and the vocal tract for sound modification. In this chapter, the laryngeal sound generation is examined in closer detail, with a special focus on singing voice production. In particular, the relation between the quality of vocal fold vibration, the consistence of the glottal airflow, and the spectral composition of the resulting laryngeal sound output (before being filtered by the vocal tract) is discussed. Two basic physiological parameters for controlling these features are described: cartilaginous adduction (controlled along the dimension of “breathy” vs. “pressed” voice); and membranous medialization (influenced by the choice of singing voice register). It is shown that these two physiological parameters can be varied independently, and how they can be incorporated into a pedagogical model. Based on this model, a typical application from the singing studio is described. Finally, the range of sound qualities resulting from independent variation of cartilaginous adduction and membranous medialization is being commented on by five known voice pedagogues, in an attempt to unify the respective terminology in voice pedagogy.

First Time

Companion animal-directed speech (CADS) has previously been investigated in comparison to infant-directed speech and adult-directed speech. To investigate the influence of owner caregiving, attachment pattern, and personality on CADS, we used the Ainsworth strange situation procedure. It allowed us to assess voice source parameters of CADS across different contexts. We extracted speech parameters (voicing duration, voice pitch, pitch range, and jitter) from 53 dog owners recorded during the procedure. We found that owner personality and gender but not caregiving/attachment behavior affect their voice’s pitch, range, and jitter during CADS. Further, we found a differential and context-specific modification of pitch and range, consistent with the idea that pitch communicates affect, whereas range is more of an attention-getting device. This differential usage, and the increased pitch, emphasize and support the parallels described between CADS and infant-directed speech. For the first time, we also show the effect of personality on CADS and lay the basis for including jitter as a potentially useful measure in CADS.
