Abstract
A doll, apparently capable of learning through a combination of human speech and touch interaction, includes a speech generator for generating upon actuation the currently indexed sound in a predetermined sequence of sounds. The sequence of sounds evidences a stepwise learning process defined by a plurality of learning steps, each step being composed in turn of a predetermined subsequence of wrong sounds followed by correct sounds. A speech detector detects human speech when energized and, in response thereto, indexes the subsequence of sounds to the next sound within the current step and actuates the speech generator and, at the end of each step, indexes the sequence of sounds to the first sound of the next step and causes the speech generator to request the selected touch. A touch detector detects a selected touch when energized and, in response thereto, actuates the speech generator. The speech generator is responsive to each appropriate actuation of the speech and touch detectors for promptly generating the currently indexed sound after deactuation of the speech and touch detectors.
