Abstract
A doll containing an endless loop tape deck having multiple tracks speaking in a normal tone and volume when a switch in its hand is closed and in a whisper tone and volume when a switch in its chest is closed. Certain tracks of the tape are for whispered message. Other tracks are for normal voice messages. Each of the multiple message segments recorded on the tape may vary in length between segments and between the tracks in a segment. A buffer zone between segments allows all tracks in each segment to que up regardless of the varying length of the messages on each track within the previous segment. A low frequency signal of 40 Hz equalizes the length of the messages on each track within each segment. The low frequency signal overlays the signals on the whisper track. The system will shut off whenever there is more than a short duration of blank space on the track. The 40-Hz signal keeps the tape mechanism active during vocal phrases and during reproduction of the whisper segments.
