A videotape of aerodynamic techniques for making measurements during speech production will be presented. Equipment shown will be: (1) a circumferentially vented pneumotachograph mask for sensing oral air flow [M. Rothenberg, J. Speech Hear. Res. 20, 155--176 (1977)], (2) a pitot tube for sensing intraoral air pressure, (3) a respirometer for air volume displacements, (4) a rotameter for calibrating airflow, and (5) a U-tube water manometer for calibrating air pressure. Discussion of calibration techniques and possible measurements during speech tasks will be displayed. A short segment of the tape will also demonstrate making simultaneous respiratory kinematic measures with linearized magnetometers using a child subject. Measures of lung volume, ribcage volume, and abdominal volume displacements will be shown. [Research supported by NIH.]
