A toy figure has a movable mouth coupled to an actuator in the belly area. A speech generator stores sound elements for an entire song, verse, or nursery rhyme. The speech generator is provided with a first track of sequenced sound elements (singing version) that form a song when sequentially generated, and a related second track of a like number of sequenced sound elements (humming version). Sound elements from the first and second tracks are interchangeable at any given point during sequential output thereof. A switch located in the mouth is connected to the speech generator to provide input as to the mouth position, i.e. open or closed. Squeezing the belly of the figure opens the mouth, changing the state of the switch and initiating an output sequence from the speech generator. When the mouth is open, the child is able to easily control the mouth position by varying the pressure on the belly actuator. The speech generator checks the state of the mouth switch at given intervals. If the speech generator senses that the mouth is closed, the speech generator switches tracks to begin output of the next corresponding "bumming" segment of the song. The speech generator continues to check the state of the switch, and if the switch is then reopened, the toy begins to sing again at the same point within the sequenced output.
