Voice source characteristics as derived from inverse filtering were analyzed in 6 country singers' speech and singing. Results showed that the closed quotient varied systematically with vocal loudness, and that glottal compliance (the ratio between transglottal AC volume displacement and subglottal pressure) decreased with increases in fundamental frequency but remained unaffected by vocal loudness. No striking differences were found in source characteristics between speech and singing within subjects. The degree of phonatory press, as judged by a panel of 19 expert listeners, appeared related to the range in which the singer was singing and to the sound pressure level gain from a doubling of subglottal pressure.

Musical theatre singing typically requires females to use two vocal registers. Physiological differences between these registers, however, have not been explicated. Our investigation considered voice source and subglottal pressure Ps characteristics of these registers, here referred to as chest and head register. These were studied by inverse filtering the oral airflow recorded for a sequence of /pae/ syllables sung at
