A compact electronic calculator comprising a screen, electronic circuits, a microphone, voice recognition circuits which are exchangeable depending upon the context of the verbal data to be received by the calculator and the language in which the data is provided. The calculator is thus responsive to numerals and symbols spoken in a selected language or languages and this is transformed through the circuitry of the calculator to be seen on an elongated display unit. A calculator is also responsive to action words such as "multiply", "divide", "add" and "subtract", so that the calculator carries out these functions on the displayed numerals and symbols. The calculator does not have a keyboard and is of a small size, approximately ten centimeters in length, one centimeter in width and one-half centimeter in depth. It can be incorporated in a pen form or, in a smaller version, incorporated into a wristband or the like. The microphone is preferably uni-directional although it may also be such that it receives voice signals from a number of different directions. The calculator is adjustable so that different selected acoustical decibel levels may be required to actuate the calculator.
