In this paper, we chose two infants as examinee, measuring fundamental frequency of crying sound section. We developed speech signal analysis platform, and through the analysis we found that infant have falling tone, flat tone, rising tone, rising-falling tone before three month, and there is no corresponding relationship between gender and fundamental frequency of infant crying signal.
