Modeling of a “What You Hear is What You Speak” (WYHIWYS) device

Humans, at times find it difficult recognizing their own voices. This is specifically true when a person´s voice is recorded and played back to him - he usually finds a marked difference between the recording and the way he feels his voice sounds. In this paper, the various possible physical and physiological reasons behind this phenomenon are expounded. Based on the conclusions, a `What You Hear is What You Speak´ (WYHIWYS) device is modeled from signal and audio processing principles. Such a device is expected to work complementary to devices such as bone conduction microphones and auditory aids, besides helping analyze various psychoacoustic effects. The device is also expected to benefit orators, vocal artists and ventriloquists in better understanding public perception of their voices. Results of the modeling are presented with respect to psychoacoustic evaluation.
