  • Abstract
    The combined effects of time delay and the action of a particular type of echo suppressor have been evaluated during a controlled experiment. Users performed a highly structured task designed to approximate real conversation either over a normal, control circuit or over one having 620 ms of delay and fitted with an echo suppressor. Little difference was noted in user reaction to, and acceptance of, the experimental circuit compared with the control circuit.
