Abstract: Non-looped continuous sound made up of random sequencing of digital sound segments is generated by taking several short segments of an otherwise continuous sound and forming independent records of those short segments. The stored segments are re-assembled into a sound sequence of arbitrary length based on selecting the next sound segment according to some statistical algorithm. The selected algorithm may be simply a random or pseudo-random selection, or it may provide a probability weighting to emphasize some sound records over others, or some combination of factors also affected by external stimuli such as light, heat or operator input. The selection of sound segments proceeds according to a logical sequence which is programmable. Sounds are organized into groups of similar sounds which may be accessed according to subsects. Groups may include beginning (head), middle and end (tail) sound segments.

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.

Abstract: A gift item which is illustrated in the form of a stuffed teddy bear houses a control system which incorporates a re-programmable solid state analog memory device which is used to record a message. In the illustrated embodiment, a write switch is housed in the teddy bear's ear, and while it is being squeezed, a microphone in the main control system will record a spoken message into the non-volatile analog memory. The recording will take place as long as the two-contact switch is squeezed, and will stop upon release of the switch or expiration of the memory capacity of the memory device, which is about 20 seconds. The message is played back by momentary compression of another two-contact switch placed in the bear's paw, which would typically be done by a child. Replacement of a prior message with a subsequent one can be done at will by closing the write switch again as was done initially.
