Zusammenfassung:A method for controlling a voice recognition module of a household appliance, a voice recognition module of said household appliance, and a household appliance are provided. The voice recognition module is in a dormant state, and the voice recognition module includes a microphone array and a speaker. Steps of the method include: at least one microphone being in an awake state, and controlling the speaker to send a sound wave signal after the at least one microphone receives a sound; the at least one microphone receiving an echo of the sound wave signal, and obtaining a current echo graph in a space where the voice recognition module is located; and comparing the current echo graph with a preset echo graph, so as to control the voice recognition module. By means of this solution, the voice recognition module can be woken up when it is detected that a user needs to use a voice recognition function, thereby reducing energy consumption and costs.
