Title:
ADDRESS INFORMATION-BASED BLACKLIST IDENTIFICATION METHOD, APPARATUS, DEVICE, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/051533
Kind Code:
A1
Abstract:
The present application relates to the field of artificial intelligence, and disclosed therein are an address information-based blacklist identification method, an apparatus, a device, and a storage medium, which are used for dividing a blacklist feature library into blacklist feature sub-libraries having smaller dimensions and comparing voiceprint features according to the blacklist feature sub-library corresponding to address information, thereby improving the voiceprint identification efficiency. The method according to the present application comprises: acquiring a voice file of a target user, the voice file comprising audio and address information, and the address information comprising an incoming telephone segment or/and Internet Protocol (IP) address information; carrying out feature extraction on the audio by means of a preset algorithm to obtain a feature file; determining whether the feature file is valid or not; if the feature file is invalid, generating a status code that extraction has failed; and if the feature file is valid, determining according to the incoming telephone segment or the IP information a target address range to which the target user belongs, calling a preconfigured blacklist model and the target address range to perform similarity scoring on the feature file, and performing a corresponding operation according to the scoring result.
