TIMER

PURPOSE:To eliminate mechanical input operations by inputting a reference voice to a timer to set the mode of the timer at a correction mode for the hour and time and inputting the hour and time desired to be corrected and set by voice thereto. CONSTITUTION:Voice is converted to an electric signal by a microphone and is standardized after extraction and binary coding at specified time intervals. A gate of a RAM is opened for the fixed time to wait for the correction voice when the specific signal for starting correction is inputted. The correction voice, when inputted within the specified time, is converted by the microphone to voltage waveforms which are subjected to a standardizing, punctuating of words and speed recognizing and are stored into a buffer memory. The stored information is read out one after another so that the time is corrected by a driving device. The gate of the buffer memory closes upon lapse of the specified time after the input of the specific signal. The gate remains closed until the next specific signal is inputted. The mode of the memory is kept displayed. The specific signal (reference signal) is preferably >=3 words to prevent malfunction. The timer operates with the desired signal if a learning function is provided to the speech recognition.
