Abstract: The present disclosure provides a voice wakeup method, apparatus and system, a cloud server and a readable medium. The method comprises: receiving a first request input by the user in a voice manner after a smart device enters a voice recognition phase; judging whether the first request after semantic parsing is consistent with pre-stored wakeup words; determining that the received first request is used to re-wake up the smart device if the first request is consistent with the pre-stored wakeup words. According to the above technical solutions, after the smart device enters the voice recognition phase, if the received first request is the wakeup words, the smart device does not perform service satisfaction processing for the first request. Capability of recognizing that the first request is re-wakeup does not cause a command recognition error and thereby can satisfy the user's expectation.
