Abstract: Different methods of providing security of sensitive/personal data have been developed which include Personal Identification Numbers (PINs), Passwords, Identity Cards, etc. and these have not been successful enough in providing the required security. Passwords can be easily forgotten or stolen, ID cards can be forged and this stresses the need for improving security by the use of the voice, which is unique to each person and cannot be stolen and is very difficult to forge. The voice among other biometric features is the safest level of protection of sensitive/personal data, therefore this research provide a framework of a text dependent speaker identification system which serves as a security tools in system operations so that by identifying the voice of a user there cannot be any denial of transactions within the system.
