In an automatic dial telephone that is usuable in a motor vehicle, when a voice input is provided during a period in which input of the names of called parties is awaited, a voice pattern of the name of the called party is compared with reference patterns of called parties stored in reference pattern storing device, to determine the degree of the similarity therebetween. The names of the called parties are output to a user in the order of decreasing degree of similarity. Each time the name of a called party is output, a command word for confirmation is a waited from a user for a predetermined time period. When a voice confirmation command is input and is recognized during this waiting period, a telephone number corresponding to the name of the called party is supplied to a channel. Consequently, the command word for confirmation may be input only if the name of the called party outputted is one desired by the user. Sensors continually monitor the driving condition of the motor vehicle in which the telephone is installed. When the operation of the steering wheel or brakes of the motor vehicle exceeds a predetermined threshold or the speed of the motor vehicle is excessive, the sensors generate safety signals that inhibit the operation of the telephone.

The invention is directed to a prower-supply transfer apparatus for a telephone wherein the power supply is fed from a telephone line by a power supply transferring circuit when the operation has been decided as a low speed operation by a speed deciding circuit, the power supply is fed from a separate power supply circuit by the power-supply transferring circuit when the operation has been decided as the high speed operation, so that the low-speed operation is performed through the speed control by the speed decision result not only when the processing may be performed even at the low speed operation in the common telephone or the like, but also when the high-speed processing is required in voice recognition or the like.

Power-supply transfer apparatus for telephone

An automatic on-hook arrangement which includes a voice detecting circuit for detecting input voice from a micro-phone, a timer for measuring time in which the input voice from the micro-phone is not detected, a warning section which emits warning upon measurement of a predetermined time by the timer, a warning releasing switch for releasing the warning, a telephone line control circuit for cutting off a telephone line, and a control section connected to each of the above components. The warning section emits the warning when the input voice is not detected for the predetermined time by the voice detecting circuit, and the telephone line control circuit cuts off the telephone line when the warning is not released, and further, the input voice is not detected for another predetermined time.

Automatic on-hook arrangement

Correction of a voice reference pattern of a so-called voice recognizing telephone having a voice recognizing function, whereby the frequency of voices inputted before the voices are correctly recognized is measured by the counter, the voice reference pattern may be corrected by the voice pattern correcting circuit in accordance with the voice inputting frequency, so that a practical voice recognizing telephone which is capable of high recognition ratio may be provided.
