Interaction terminal switching method and device, and interaction recording and broadcasting system

The embodiment of the invention discloses an interaction terminal switching method used for solving the problems that an existing switching mode of an interaction terminal is prone to error, low in switching efficiency, and easy to disrupt an interaction rhythm of a whole system. The method provided by the embodiment of the invention comprises the steps of detecting voice information of a main meeting-place and/or a branch meeting-place in current interaction; performing voice recognition on the detected voice information to acquire a recognition result; extracting a keyword of the recognition result, thus acquiring a command keyword; generating a terminal switching command according to the command keyword; and performing interaction terminal switching on the main meeting-place and/or the branch meeting-place in current interaction according to the terminal switching command. The embodiment of the invention also provides an interaction terminal switching device and an interaction recording and broadcasting sy
