This research is based on the study of such parameters those separates a scream of distress from a hoot in the joy of a person specifically women, having objective to design and develop security devices based on women emotions to provide them security. The present study has used high-reliability audio recordings to capture the acoustic features of both high pitch signals of women. Results indicated that perceptually categorized both the signals have distinct acoustic features. Distress scream reflect a slightly higher level of intensity than joyful scream. Moreover, the duration of the signal plays a vital role.
