An electronic apparatus capable of producing a voiced output representing various data input thereto and the results of operations on the input data includes a system for inhibiting the voiced output of data that is unnecessary to the operator. For example, when input data overflows the apparatus, a voiced output indicative thereof is inhibited. As another example, when input data or the result of an operation is a whole number, a voiced output indicative of decimal point location is inhibited. As still another example, if key entries are made too rapidly to permit a voiced output, such output is inhibited.
