3. A speech categorization system for recognizing at least one spoken itemized expression appearing in a communication, comprising: an amplifier receiving said communication and amplifying said speech to produce a speech signal; a comparator connected to said amplifier, said comparator comparing the speech signal to a threshold value and generating a high amplitude signal when the speech signal is greater than the threshold value and generating a low amplitude signal when said speech signal is less than the threshold value; a timer for counting the duration of the high amplitude signal and the duration of the low amplitude signal; and means for determining if a spoken itemized expression has occurred by relating the duration of the high amplitude signal and the duration of the low amplitude signal.

A system as in claim 3, further comprising means for comparing the duration of the high amplitude signal with a predetermined period.
