VOICE PRODUCTION FROM THE MOVEMENTS OF A HAND

Research output: Contribution to journalArticlepeer-review

Abstract

The system presented allows the interpretation of the movements of a hand. With sensors integrated with a Micro Bit card and the use of recorded voice, the concatenation of phonemes is generated. The result allows relating each degree of movement of a hand with the X and Y axes to reproduce a specific phoneme. Time-series analysis is performed in a range from -90o to 90o for both the X and Y axes; in such a way that by comparing the data generated and those previously stored, it is possible to relate a movement to a specific phoneme. In the concatenation of phonemes, recursion was used through graphs. Therefore, audio output is delivered. Intelligibility greater than 84% is obtained for a total of 350 phonemes. The system was developed using recursive functions in graphs.
