Title: PROACTIVE SEARCHING METHOD AND DEVICE BASED ON SPEECH RECOGNITION
Abstract:
A proactive searching method and device based on speech recognition are provided. The method comprises: analyzing a received voice message, to obtain a speech feature vector of the voice message (S301); determining whether the speech feature vector matches a reference speech feature vector preset by a user, and obtaining a corresponding determination result (S302); if the determination result is that the speech feature vector does not match the reference speech feature vector, generating, on the basis of the analysis of the voice message, a subject domain corresponding to the voice message (S303); mapping and extending the subject domain to obtain a corresponding search structure (S304); and performing a proactive matching search according to the search structure, to obtain corresponding subject information, and presenting the subject information to the user (S305). Whether the speech feature vector of the received voice message matches the reference speech feature vector is used as a criterion for whether to enable a search function. Related information or a summary is fed back to the user in real time, such that the user can rapidly obtain unknown information in a timely manner, thereby solving the problem of information asymmetry during communication or in a foreign-language environment.
