METHOD, SYSTEM, AND ELECTRONIC APPARATUS FOR DETECTING CHANGE OF TARGET USER, AND STORAGE MEDIUM

A method, a system, and an electronic apparatus for detecting a change of target user during voice interaction, and a storage medium. The detection method comprises: after a sound recording apparatus starts sound recording, acquiring, upon detecting that a target user has started inputting a voice signal, a first preset number of first voice signal frames; acquiring a first pitch period and a first pitch period sequence; after a preset duration, acquiring a second preset number of second voice signal frames; acquiring a second pitch period and a second pitch period sequence; and if a current user inputting the second voice signal frames is determined as not being the target user according to the first pitch period sequence and the second pitch period sequence, controlling the sound recording apparatus to terminate sound recording. The method enables immediate termination of sound recording when a target user has stopped talking and a non-target user is inputting voice signal, thereby preventing errors in subs
