This paper presents a secure voice authentication system combining speaker verification and token technology. The dual-factor authentication system is especially designed to counteract imposture by pre-recorded speech and the text-to-speech voice cloning (TTSVC) technology, as well as to regulate the inconsistency of audio characteristics among different handsets. The token device generates and prompts a one-time passcode (OTP) to the user. The spoken OTP is then forwarded simultaneously to both a speaker verification module, which verifies the user's voice, and a speech recognition module, which converts the spoken OTP to text and validates it. Thus, the OTP protects against recorded speech or voice cloning attacks and speaker verification protects against the use of a lost or stolen token device. We show the preliminary results of our Support Vector Machine (SVM)-based speaker verification algorithm, handset identification algorithm, and the system architecture of our design.
