Flow Glottogram and Subglottal Pressure Relationship in Singers and Untrained Voices

摘要: This article combines results from three earlier investigations of the glottal voice source during phonation at varying degrees vocal loudness (1) in five classically trained baritone singers (Sundberg et al., 1999), (2) 15 female and 14 male untrained voices 2005), (3) rated as hyperfunctional by an expert panel (Millgard 2015). Voice data were obtained inverse filtering. Associated subglottal pressures estimated oral pressure occlusion for consonant /p/. Five flow glottogram parameters, maximum declination rate (MFDR), peak-to-peak pulse amplitude, level difference between first second harmonics source, (4) closed quotient, (5) normalized amplitude averaged across singer subjects related to associated MFDR values. Strong, quantitative relations, expressed equations, are found each other parameters. The values voices, well those hyperfunctional, deviate systematically derived equations.
