Abstract

An electronic telephone including a keyboard input, a telephone line interface, a speech synthesis device with a control line and an audio line coupled to the telephone line interface, a message recorder with an audio line coupled to a telephone line interface, and an electronic digital processor system to control the device. The electronic digital processor system includes two independent and separably operable central processing units. One central processing unit is activated by the keyboard when a telephone number is input and may be used to store numerous, frequently called telephone numbers.

Claims
