The invention discloses an intelligent voice interaction system and method. The system comprises a preprocessing module, a strategy flow module, a central control module, an automatic call-out module,a voice synthesis module, a voice recognition module and a language processing module, wherein the central control module is internally provided with a central control scheduling module for scheduling the strategy flow module, the automatic call-out module and the language processing module. The method comprises the steps of 1-12. According to the method, integrated scheduling of multiple algorithms can be realized, multiple algorithm models are scheduled according to set rules for calculation, and an optimal solution is obtained by integrating calculation results, so that the limitation of blind spot calculation of a single algorithm model is solved, and a complementary effect is achieved; complex answers such as multiple questions, multiple intentions and the like are processed; and thecentral control scheduling module performs preliminary preprocessing before the text is sent to the question calculation model, decomposes questions with multiple intentions into multiple parts through the multi-intention splitting calculation model, then sends the multiple parts to the question calculation model, integrates answer results after obtaining multiple answers, and feeds back the answer results to the client.
