Comparison of normal and disguised voice on basis of pitch and fundamental frequency
People generally changed their voices to hide their identities for many purposes, for example to make emergency police calls, for extortion and also for kidnapping. Disguise voice may be defined as an intentional action of a speaker who wants to change his voice for falsifying reason. There is change in values of fundamental frequency and pitch pattern before and after disguise voice. A comparison of each disguise voice with normal voice was taken to put check on speaker identification and verification. The results show that there exists a linear relationship between fundamental frequency and pitch pattern for both normal and disguised voice.
