Calculator for blind with self-correction feature using voice output is used to help blind to increase their skill in calculation. This tool is an interesting topic to be explored because there is not self correction in common calculator for blind people. Self correction is used for blind to practice their braille reading. The proposed feature in this research is self-correction. By using this feature, all of the answer given by the blind using voice and number input will be corrected automatically by the system. The self-correction mechanism is active while the blind calculates number using braille calculator. After the result calculation is showed in braille calculator, then the blind could speak the result by reading the braille calculator into it. Then the braille calculator will check the answers that blind given into it. The answer from blind will be converted from speech to text. Then, the text will be identified by system. When it has been identified, this system will be given the response correct answer automatically. So, the blind can learn the correct answer and improve the braille reading, especially in reading number.
