Talking Calculators

Talking calculators use a built-in speech synthesizer to speak number, symbol or operation keys as they are pressed. They also read answers from completed calculations. Hearing the numbers or symbols may help some people find input errors, such as pressing the wrong key. Also, hearing the answer aloud helps users double-check for errors that may have been made when copying numbers, such as transposing 91 for 19, or confusing a 6 with a 9.
