Abstract : Speaker Verification software, or voice biometrics, is technology that relies on that fact that we all have a unique voice that identifies us. Speaker verification software is most commonly used in security applications, such as gaining access to restricted areas of a building, or computer files by using your voice. It is also used in call centers where clients say the menu which they wish to select. In many applications, speech may be the main or only means of transferring information and so would provide a simpler method for authentication. The telephone system provides a familiar network for obtaining and delivering the speech signal. For telephony based applications, there would be no need for any equipment or networks to be installed as the telephone and mobile network would suffice. For non-telephone applications, soundcards and microphones are available as a cheap alternative. In our application we are making a speaker identification software that identify the person on the call when he say “hello” and give us the name of the speaker if we already know that speaker in our software database.
