VOICE AUTHENTICATION DEVICE, VOICE AUTHENTICATION SYSTEM, AND VOICE AUTHENTICATION METHOD

摘要

A voice authentication apparatus capable of reliably performing personal identification based on a communicating party's voice of an incoming call between communication terminal apparatus and preventing communication with ill-intentioned people. In this apparatus, when the communicating party is specified through key operation of user specification input section 201, a user specification signal is outputted to voice data sample storage section 202. At communication section 205, a received voice signal received from mobile telephone apparatus 100 is outputted to voice verification section 203. Voice data sample storage section 202 reads the corresponding voice sample data according to the user specification signal inputted from user specification input section 201 and output as a corresponding sample signal to voice verification section 203. Voice verification section 203 verifies the received voice signal inputted from communication section 205 against the corresponding sample signal inputted from voice data sample storage section 202 and outputs the verification result as a verification result signal to display section 204.
