Estimating the time to reach a target frequency in singing

Area of Science:

• Auditory Neuroscience
• Speech and Hearing Science
• Music Cognition

Background:

• Proficient singing requires accurate and rapid pitch matching.
• Existing methods for analyzing vocal pitch control have limitations in sensitivity.

Purpose of the Study:

• To introduce a novel technique for estimating vocal target frequency attainment time.
• To evaluate the sensitivity of this new measure to tonal priming effects.
• To investigate the influence of tonality and pitch height on untrained singers' vocal productions.

Main Methods:

• Development of adaptive optimal-kernel (AOK) time-frequency representations.
• Optimization of the time-frequency tradeoff at each time point for precise analysis.
• Experimental comparison of the AOK measure against onset latency measurement.
• Application of the AOK analysis to vocal recordings of untrained singers.

Main Results:

• The AOK time-frequency measure demonstrated higher sensitivity to tonal priming effects than onset latency.
• Analysis revealed significant effects of tonality on vocal productions.
• Pitch height was also found to influence vocal performance in untrained singers.

Conclusions:

• The AOK technique offers a more sensitive approach to analyzing vocal pitch control.
• This method provides new insights into the cognitive and acoustic factors influencing singing accuracy.
• Findings contribute to understanding vocal learning and auditory feedback mechanisms in singers.
