Vocal Tract Morphology in Inhaling Singing: Characteristics During Vowel Production-A Case Study in a Professional Singer.

Background: A professional singer produced various vowels on a comfortable loudness and pitch in an inspiratory and expiratory phonation manner. The present study investigates the morphological differences and tries to find a link with the acoustical characteristics.

Objectives/hypothesis: We hypothesize that features, constantly present over all vowels, characterize inhaling phonation and that the formant frequencies reflect the morphological findings.

Vocal Tract Morphology in Inhaling Singing: An MRI-Based Study.

Objectives/hypothesis: Inhaling singing is a recently developed singing technique explored by the soprano singer Françoise Vanhecke. It is based on an inspiratory airflow instead of an expiratory airflow. This article describes the anatomical structural differences of the vocal tract between inhaling and exhaling singing.
