Abstract

The invention discloses a voice anomaly detection method and device, and the method comprises steps: obtaining voice information to be detected and determining corresponding voice information features, and then inputting the voice information features into a pre-trained recognition model; obtaining a recognition result for the to-be-detected voice information so as to perform voice anomaly detection on the to-be-detected voice information; if it is determined that the to-be-detected voice information is abnormal voice information and the voice information re-acquired from the voice source corresponding to the to-be-detected voice information is still abnormal voice information under the condition that the standby service equipment is started, determining that a network voice attack behavior exists, and through a preset exception processing strategy, processing the voice source. Thus, anomaly detection is carried out on the intelligent voice response window session, attack behaviors of lawbreakers can be recognized, and the preset anomaly processing strategy can be adopted to process the voice source, so that the attack behaviors of the lawbreakers are prevented, and the system stability is maintained.

Description

technical field [0001] This description relates to the field of computer technology, and in particular to a method and device for abnormal speech detection. Background technique [0002] At present, intelligent voice response technology has been greatly developed and applied to fields such as intelligent customer service and information search, which not only effectively improves the execution efficiency of some businesses in these fields, but also brings great benefits to users' daily life convenient. [0003] In practical applications, some criminals may attack the platform that provides intelligent voice response, for example, continue to occupy the intelligent voice response window of the platform, so that other users who need to perform voice response services cannot perform services smoothly. In order to cope with the adverse effects brought by this situation, in the prior art, the platform usually adopts the method of capacity expansion, that is, increasing the numbe...
