This study was conducted to determine changes of voice after consuming raw egg, apple, and pear. Ten college students vocalized /a/ before and after having raw egg, apple, and pear. Dr. Speech was utilized to obtain acoustic changes of subjects/ voice. At-test was performed to analyze changes of voice before and after consuming raw egg, apple, and pear. No significant difference was found in acoustic measurements before and after having the 3 food items. However, the subjects seemed to show some improvements in jitter, HNR, and NNE in the order of raw egg, apple and pear even though they did not reach a statistical significaance. It was concluded that a more systematic research paradigm was needed in order to objectively reject or substantiate the results of the current investigation.
