Voice control method and device based on smart home system

The embodiment of the invention provides a voice control method and device based on a smart home system. The smart home system comprises at least one smart device and a home edge server. The method comprises the following steps: a home edge server receives a user audio signal collected by intelligent equipment; the home edge server performs voice recognition on the audio signal to obtain text information; the home edge server determines a user instruction corresponding to the text information based on the preset instruction word, and the user instruction is used for completing the control operation indicated by the user audio signal. And the privacy of the user is effectively protected. And recognition calculation is performed through the independently arranged home edge server, so that the time for uploading the audio signals of the users to the cloud server is saved, the problems of multi-user concurrency and queue delay during processing by the cloud server are avoided, the speed of voice control is increa
