A study on recovery in voice analysis through vocal changes before and after speech using speech signal processing

초록

Generally speaking, the lecturers have a very large voice and a voice with a high vocal tone. In this study, we propose a new method to perform a vocal massage by placing a reflective cup on the mouth in order to make the hoarse voice normal. We learned about the sound characteristics of hoarse voices and suggested a way to cope with them. When applying the method of removing hoarseness after lecture, the average voice recovery of 94% was obtained. In addition, the clarity of the voices following the resounding of the hoarse voice compared to the voices before the lecture became clearer. © Research India Publications.
