1. Weighing apparatus comprising: first means for sensing the weight of an article and generating an analog signal indicative of the weight sensed, second means for receiving, processing and analyzing said analog signal and generating first digital signals indicative of the weight sensed by said first means, third means including electrically operated indicating means for indicating a variable associated with the article sensed by said first means, a microphone, first electronic computing means connected to receive speech signals output by said microphone, process and analyze same and generate first control signals, second electronic computing means operable to receive said first digital signals and said first control signals and to perfrom a computing function with respect to the information defined by said signals and to generate second control signals defining information relating to computations involving said first digital weight defining signals and said first control signals generated by said first electronic computing means, and means for applying said second control signals to selectively control the operation of said electrically operated indicating means to cause said indicating means to indicate the information defined by said second control signals.
3. Weighing apparatus in accordance with claim 1 wherein said electrically operated indicating means is operable to provide an intelligible indication of the cost of the product defined by the article weighed.
