Abstract: A portable electronic dictionary and language interpreter includes a control circuit for conducting retrieval of one or more full-length words on the basis of a non full-length form entered by an input device. The one or more complete words are preliminarily stored in a memory such as a read-only memory (ROM). The control circuit is activated by a search key provided on the main frame of the portable device. According to the repetition of the actuation of the search key, a plurality of full-length words are successively developed from the memory and then indicated in a display. In another form of the present invention, another type of search key may be provided so that the plurality of full-length words can be successively developed and then indicated.

Abstract: An electronic operation sequence instruction system is shown. This system audibly instructs an operator of an operation sequence through the use of synthetic speech. A shift register is provided for storing digital information related to operation sequence instructions. The digital information stored in the shift register is progressively applied to a synthetic speech control system, which develops synthetic speech in accordance with the digital information applied thereto. Thus, an audible set of instructions is presented to an operator.

Abstract: A speech-synthesizer timepiece disclosed herein is adapted to provide audible sounds indicative of time and/or calender information. The audible sounds are followed by an adjective phrase which represents such a unit of the preceding time and/or calender information as month, day, day of the week, hours, and minutes. The adjective phrase consists of one or more audible sounds like that indicative of the body of the time and/or calender information.

Abstract: A speech-synthesizer timepiece is adapted to produce audible sounds indicative of updated time information at a desired point in time through the use of the speech synthesizing technique. To avoid the user's failure to listen to the audible sounds or to avoid the user's error in dictating the audible sounds, an advance announcement is generated which includes a monotonous sound, a simple phrase or sentence. This advance announcement is provided when the audible sounds indicative of updated time is about to develop.
