Relations of singing talent with voice onset time of trained and untrained female singers

This study examined phonatory-articulatory timing during sung productions by trained and untrained female singers with and without singing talent. 31 untrained female singers were divided into two groups (talented or untalented) based on the perceptual judgments of singing talent by two experienced vocal instructors. In addition to the untrained singers, 24 trained female singers were recorded singing America the Beautiful, and voice onset time was measured for selected words containing /p, b, g, k/. Univariate analyses of variance indicated that phonatory-articulatory timing, as measured with voice onset time, was different among the three groups for /g/, with the untrained-untalented singers displaying longer voice onset time than the trained singers. No other significant differences were observed across the other phonemes. Despite a significant difference observed, relatively small effect sizes and statistical power make it difficult to draw any conclusions regarding the usefulness of voice onset time as an indicator of singing talent.
