Flow Glottogram and Subglottal Pressure Relationship in Singers and Untrained Voices

This article combines results from three earlier investigations of the glottal voice source during phonation at varying degrees of vocal loudness (1) in five classically trained baritone singers (Sundberg et al., 1999), (2) in 15 female and 14 male untrained voices (Sundberg et al., 2005), and (3) in voices rated as hyperfunctional by an expert panel (Millgård et al., 2015). Voice source data were obtained by inverse filtering. Associated subglottal pressures were estimated from oral pressure during the occlusion for the consonant /p/.
