Abstract:: Abstract: Objective To establish a rapid, accurate, safe and non-invasive mode of physiological voice monitoring. Methods The physiological voice characteristics of women in reproductive age were analyzed with auscultation and olfaction. The ovulatory period, menstrual period, and the degree of dysmenorrhea were used as the discriminatory basis to screen out the differential voice frequency characteristics that could reflect the above indications, and a regression model was established. Results Among the 242 voice indicators, there were 14, 11 and 4 voice indicators which were significantly different between ovulation and non-ovulation, menstruation and non-menstruation, and in 4 dysmenorrhea degrees, respectively. The voice resonance peak time sequence5 and the maximum energy frequency to time ratio of the most sustained frame were associated with ovulatory period and the highest energy frequency band number was negatively associated with menstrual period and the tone scale was positively correlated with the degree of dysmenorrhea. Conclusion Women of reproductive age show characteristic changes in voice during the physiological period, which has certain predictive ability for ovulation and menstruation, and has certain reference value for quantifying the degree of dysmenorrhea.
