ABSTRACT:
A speech analyzer is provided for determining the emotional state of a person by analyzing pitch or frequency perturbations in the speech pattern. The analyzer determines null points or "flat" spots in a FM demodulated speech signal and it produces an output indicative of the nulls. The output can be analyzed by the operator of the device to determine the emotional state of the person whose speech pattern is being monitored.
