Ever wanted to tell a calculator to do a calculation with just your voice? or wanted to listen to the calculation to make sure you have entered the correct calculation? Speak n Talk Calculator can do that for you!
Speak n Talk Calculator can recognize spoken compounded mathematical equations. For example you can say whats negative 2 plus 2 times 5 divided 3 minus 4 point 5 (-2+2*5/3-4.5) ? and Speak n Talk Calculator will respond with the correct result. But Wait there is more, you can also use the number keys to type in equations as well! Speak n Talk Calculator can even tell you jokes, just say "Tell me a Joke"
I recommend IVONA Text-To-Speech HQ for high quality voices over the default android voice.
Let the Speak n Talk Calculator do the Math and Speaking for you!
