Embodiment Construction
[0051]This embodiment provides an identity authentication method for an intelligent logging evaluation expert system based on voiceprint recognition. First, a voiceprint template library is constructed for each interpretation expert user of the intelligent logging evaluation expert system, and each interpretation expert is collected three times. The voiceprint waveform of the user's pronunciation of the same text is quantified, indexed by the name of the interpreter, and loaded into the encrypted database. In the process of system identity authentication, the user to be identified first specifies the name of the interpretation expert to be identified in the interpretation expert list, and then collects the voiceprint waveform of the user to be identified who pronounces the same text as the voiceprint template of the specified interpretation expert , and quantified. According to the instructions of the user to be identified, extract three voiceprint templates corresponding to t...
