Study of Airflow Out of the Mouth During Speech.
Catford, J.C.; And Others
Airflow outside the mouth is diagnostic of articulatory activities in the vocal tract, both total volume-velocity and the distribution of particle velocities over the flow-front being useful for this purpose. A system for recording and displaying both these types of information is described. This consists of a matrix of l6 hot-wire anemometer flow sensors, a PDP-4 Digital computer, an X-Y oscilloscope screen in spatial locations corresponding to the locations of the sensors and of sizes corresponding to the flow-velocity at each location, and a control box enabling the operator to select "interactive,""record," and "recall" modes of operation.
