For practical reasons, only the amplitude of the carrier phrase was somewhatcontrolled. The current American National Standards Institute standard for audiometers continues tospecify the level of the test word should be <i>the same communication level as the carrier phrase</i>.<br /><b>Purpose:</b> The development of an amplitude calibration protocol for use with short-duration speech signalsthat are characterized by substantial amplitude modulations is described.<br /><b>Research Design:</b> Protocol 1 evaluated the average maximum root-mean-square (rms) amplitudes of12.5-, 25-, 50-, and 100-ms voiced phoneme segments of each test word in 0.0227-ms increments todetermine the segment duration to use.
