Examines vocal stability during ascending glissandos in vocally untrained and trained subjects, suggesting speed influences instabilities.
INTRODUCTION: During pitch glides, instabilities of the human voice production have frequently been reported. However, the influence of speed on such instabilities has not yet been clarified. METHODOLOGY: ≈ 110 Hz). During phonation, synchronous recordings were captured by high-speed videoendoscopy, electroglottography (EGG), and audio signals. The Glottal Area Waveform (GAW) was extracted. RESULTS: exceeded the value of approximately 0.7. CONCLUSIONS: change rate indicated an effect on voice stability.
