The voice-controlled device receives a voice-controlled message of environmental sound information through a voice control interface, and broadcasts the voice-controlled message to neighboring IOT devices to drive a corresponding IOT device according to the voice-controlled message. When failing to recognize the voice-controlled message, the voice control interface uploads the voice-controlled message to a cloud server for query through the IOT server, and broadcasts a result of the query returned from the cloud server. A way of chain broadcasting is employed by the voice-controlled device to drive selected IOT device or receive returned information so as to enhance operational convenience in using IOT devices. ## Claims ### Claim 1 A method for processing information of an Internet of things (IOT) system with voice-controlled functions, wherein the method is performed by an IOT system having a voice-controlled device, multiple IOT devices and an IOT server and comprises a voice-controlled device mode, the voice-controlled device mode performed by the voice-controlled device and comprising steps of: collecting environmental sound information;
