This paper describes a computerized system (for the PDP-12) for analyzing patterns arising from two-speaker dialogues. Programs detect the presence and absence of sound from each speaker at a sampling rate specified by the user. The parameters of interest are vocalizations, pauses, interruptions, and vocal intensity. Programs are provided to count frequencies, determine durations and variabilities, plot intensities, etc. Programs are also available to aid in determining speech thresholds, examine the raw data, and measure and account for cross-talk. These programs should be useful in examining dyadic interactions and detecting disturbances in communication.
