The present invention relates to a voice authentication method, a voice authentication system using a password modulation, and a financial system including the same. The voice authentication system comprises: an auto call server connecting a call with a customer terminal, and transmitting voice information with respect to a modulation key to the customer terminal to request a modulated password; a voice recognition server receiving voice information of the modulated password from the customer terminal, and extracting the modulated password from the received voice information of the modulated password; and an authentication server modulating an intrinsic password by using the modulation key when an authentication is requested, transmitting the modulation key to the auto call server to request a call with the customer terminal, demodulating the modulated password extracted by the voice recognition server, and approving an authentication when the modulated password and the intrinsic password are identical. According to the present invention, provided are the voice authentication method, the voice authentication system using the password modulation, and the financial system including the same, thereby enhancing security and improving the reliability of the authentication. |
