A singer must perceive where the transition is occurring and apply adjustments to smooth the transition. Within register transitions, one may experience various types of vocal instabilities. The primary aim of this research was to study the production mechanisms characterizing vocal instabilities in the untrained female singer. This was an exploratory study that included five untrained female singers who produced “normal” octave scales as well as scales as smoothly as they could. Simultaneous recordings of airflow, microphone, and EGG signals were analyzed. The scales were divided into three groups based on the perceptual consensus of level of smoothness. Unsteady scales contained aphonic segments, abrupt registration fluctuations, obvious intensity changes, and unexpected fundamental frequency (fo) variations. Subtler unsteady scales exhibited noticeable but “understated” quality changes, increased speed of fo changes or overshoots, and smaller yet evident intensity variations. The participants often produced perceivably smooth scales with minimal instability. Results suggest that untrained female singers are capable of producing perceptually smooth scales across register transitions. However, within some of these perceptually smooth scales, subtle changes and disturbances were noticed that result in the perception of minor instabilities. These subtleties are often seen more clearly within the airflow signal, EGG signal shifts, and fo rate of change than are aurally perceptible. For the unsteady scales, the more obvious instabilities were seen within nearly all measures, most notably in the airflow, fo, and intensity contours, and EGG waveform width and height. This study offers insights into a wider range of steadiness of vocal production where objective recordings reveal subtle changes that are difficult to hear. 2018-04-25 English text Bowling Green State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1522340508253471 http://rave.ohiolink.edu/etdc/view?acc_num=bgsu1522340508253471 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
