“…The posterior pharyngeal wall can be actively recruited for swallowing and other functions of the vocal tract (Magen et al, 2003). It can also deform due to extreme flexion/extension of the neck (Penning, 1988) and due to pressure buildup in the pharynx (Proctor et al, 2010).…”

Purpose Adult human vocal tracts display considerable morphological variation across individuals, but the nature and extent of this variation has not been extensively studied for many vocal tract structures. There exists a need to analyze morphological variation and, even more basically, to develop a methodology for morphological analysis of the vocal tract. Such analysis will facilitate fundamental characterization of the speech production system, with broad implications from modeling to explaining inter-speaker variability. Method A data-driven methodology to automatically analyze the extent and variety of morphological variation is proposed and applied to a diverse subject pool of 36 adults. Analysis is focused on two key aspects of vocal tract structure: the midsagittal shape of the hard palate and the posterior pharyngeal wall. Result Palatal morphology varies widely in its degree of concavity, but also in anteriority and sharpness. Pharyngeal wall morphology, by contrast, varies mostly in terms of concavity alone. The distribution of morphological characteristics is complex, and analysis suggests that certain variations may be categorical in nature. Conclusion Major modes of morphological variation are identified, including their relative magnitude, distribution and categorical nature. Implications of these findings for speech articulation strategies and speech acoustics are discussed.

This paper presents an automatic procedure to analyze articulatory setting in speech production using real-time magnetic resonance imaging of the moving human vocal tract. The procedure extracts frames corresponding to inter-speech pauses, speech-ready intervals and absolute rest intervals from magnetic resonance imaging sequences of read and spontaneous speech elicited from five healthy speakers of American English and uses automatically extracted image features to quantify vocal tract posture during these intervals. Statistical analyses show significant differences between vocal tract postures adopted during inter-speech pauses and those at absolute rest before speech; the latter also exhibits a greater variability in the adopted postures. In addition, the articulatory settings adopted during inter-speech pauses in read and spontaneous speech are distinct. The results suggest that adopted vocal tract postures differ on average during rest positions, ready positions and inter-speech pauses, and might, in that order, involve an increasing degree of active control by the cognitive speech planning mechanism.

“…Pharyngeal wall movement may play a role in VP valving. The contribution of the pharyngeal wall to VP closure has been observed in a number of studies (Iglesias, Kuehn, & Morris, 1980;Magen, Kang, Tiede, & Whalen, 2003;Minifie, Hixon, Kelsey, & Woodhouse, 1970;Zagzebski, 1975). Four different patterns of VP closure which involve movement of the lateral and/or posterior pharyngeal walls (e.g.…”

This study investigated the effect of speaking rate on aerodynamic and acoustic measures of velopharyngeal (VP) function in 27 adult speakers (14 M, 13 F). The pressure-flow method (Warren & Dubois, 1964) was used to collect aerodynamic data of /m/ and /p/ segments in the word "hamper" and the utterances "Mama made some lemon jam" (MMJ) and "Buy Bobby a puppy" (BBP). A Nasometer was used to collect nasalance scores and nasalance distance for MMJ and BBP. Measures were collected under 4 speaking rate conditions (normal, fast, slow, and slowest). Results indicated that nasal airflow and VP orifice area were unaffected by speaking rate whereas intraoral pressure decreased as speaking rate slowed. Nasalance was greater for BBP at slow speaking rates and nasalance distance (MMJ -BBP) decreased at slow rates. The data was interpreted with respect to expectations set forward in the literature on normal and disordered speech motor control.ii "Curiosity has its own reason for existing" -Albert EinsteinTo everyone in my life who encouraged me to ask questions.iii ACKNOWLEDGEMENTS
