<p>A voice-controlled timing and calculating device includes a microphone to receive a user's vocal signal, a voice amplifier amplifying the vocal signal, a comparison circuit comparing the vocal signal with information stored in a memory to retrieve an associated instruction, a processor performing the instruction of serving as a timer or a calculator to generate a result, and a voice synthesizer which converts the result from the processor into a synthetic voice which is then broadcast by a speaker so that the device may be operated with vocal input and vocal output. Further, the device may be provided with visual display to show the result of the processor. Also, a manually actuateable switch may be provided to allow a user to alternatively switch the processor between the timer and the calculator. <IMAGE></p> |
