Embodiment Construction
[0031] The invention provides an identity verification system and method based on voiceprint recognition, which performs voiceprint verification and semantic verification on voice information input by a user at a terminal, thereby confirming the user's identity. Through the present invention, the user does not need to memorize any password or question answer, not only the operation is convenient, but also the problem of using recording to crack in the existing voiceprint verification system can be effectively avoided.
[0032] Such as figure 1 Shown is a schematic diagram of the first embodiment of the identity verification system of the present invention. The system includes a transceiver unit 12 , a semantic verification unit 14 , a voiceprint verification unit 15 and a voiceprint feature library 16 .
[0033] The voiceprint feature database 16 is used to store one or more voiceprint features, wherein each voiceprint feature corresponds to a user. When storing, each voicep...
