| To address the need for evidence supporting the use of vocal warm-up, speech data were recorded from 6 healthy English-speakers before and after warm-up and later analyzed acoustically and judged perceptually by unbiased listeners. Speakers were 4 high school theatre students (3 female, 1 male) and 2 college speech-language pathology students (2 female). Listeners were 6 speech-language pathology graduate students. The experiment evaluated both the acoustic and emotional effects of vocal warm-up. Results of the study indicated a slight listener preference for after warm-up voices. However, none of the results were statistically significant and thus fail to support the use of vocal warm-up as a method for improving acoustic and perceptual aspects of voice quality. |
