| Abstract: | Acoustic, glottographic, and videolaryngoscopic analyses were made of trillo, a vocal ornament described as the rapid repetition of a single note. This vocal gesture, performed by a trained singer, was studied for variations in laryngeal adduction, fundamental frequency, and acoustic amplitude characteristics. Results suggested that trillo was produced with alternating abduction/adduction of the vocal folds, and fundamental frequency tended to be lower during the relatively more abducted portions of the utterance. |
