Robot voice switching method, server and system

The invention provides a robot voice switching method, a server and a system. The method comprises the steps that S30, by means of voice and video data obtained through recognition of a current voicerecognition library, voice text data is obtained; S40, whether or not voice switching information is contained in the voice text data is judged; S50, if yes, a default configuration file is reset according to the voice switching information, an updated configuration file is obtained, and the updated configuration file is stored; S60, a voice service system is restarted, the current voice recognition library and/or a current semantic understanding library and/or a current voice synthesis library are/is modified according to the updated configuration file; S70, if not, voice response text data corresponding to the voice text data is sought through the current semantic understanding library; S80, by means of the current voice synthesis library, the voice response text data is converted into the corresponding voice re
