Scaling Articulatory Behavior: Intraoral Air Pressure

Electromyographic and intraoral air-pressure studies of bi-labial stops.

INTRODUCTION There have been a number of electromyographic (EMG) studies of the lips (Harris et al. 1965; Fromkin 1966; Perrin and Scharf 1970; Tatham and Morton 1968a, 1968b, 1970), at least one Lubker and Parris 1970) involving simultaneous measurement of intraoral air pressure behind bilabial stops. The experiment reported here was one of a series designed to throw light on the problem of de...

The effect of vowel context on consonantal intraoral air pressure.

Temperature-pressure scaling for air-fluidized grains near jamming.

We present experiments on a monolayer of air-fluidized beads in which a jamming transition is approached by increasing pressure, increasing packing fraction, and decreasing kinetic energy. This is accomplished, along with a noninvasive measurement of pressure, by tilting the system and examining behavior versus depth. We construct an equation of state and analyze relaxation time versus effectiv...

Effect of age, gender, and repeated measures on intraoral air pressure in normal adults.

The effect of age, gender, and repeated measures on intraoral air pressure (P0) was examined. Sixty adults comprised of 10 males and 10 females in each of three age groups (i.e., 20-39, 40-59, and 60-83 years) participated. P0 was assessed during voiceless stop plosive /p/ productions in repeated vowel/consonant syllables. The three medial plosives of a seven-syllable train were averaged to com...

Signal Processing of Intraoral Pressure Curves

Human teeth are susceptible to pressure exertion ; the exertion of a constant low force between 0.1 and 0.5 N results in a change in tooth position ( Prof t, 1978 ). Therefore, tooth alignment in subjects who have not undergone orthodontic treatment is a product of an equilibrium of forces exerted on the teeth. Beside pressure from the lips ( Thüer and Ingervall, 1986 ), the cheeks , and the t...
