processor can be programmed to calculate a traveled distance , and to emit the answer in an audible format via the speakers . optionally , a processor can be programmed to recognize spoken statistical questions , and to process such questions by accessing a statistical database . hence , a user can ask the toy “ ball , who won the soccer world cup in 1966 ?” and the processor controls the speakers
