Pharyngeal articulation in the production of voiced and voiceless fricatives

Michael I. Proctor, Christine H. Shadle, Khalil Iskarous
2010 Journal of the Acoustical Society of America  
For one speaker, pharyngeal volume during the production of voiceless labial fricatives was found to be greater, and sibilant pharyngeal volume varied with vocalic context as well as voicing.  ...  For three speakers, all four voiced oral fricatives were produced with a larger pharynx than that used during the production of the voiceless fricative at the same place of articulation.  ...  High quality acoustic recordings were made during the anechoic sessions to allow for acoustic analysis of the speakers' fricatives.  ...
