In addition, the order of the operations may be re-arranged. The process may be terminated when its operations are completed, but may have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, and the like.
Example one
Fig. 1 is a flowchart of a control method for an electrical device according to an embodiment of the present invention, where the present embodiment is applicable to a case of controlling an electrical device, and is applied to a voice acquisition module.

And then the voice acquisition module sends the voice command information to the main control module after receiving the starting response fed back by the main control module, and the specific function content required by the electric equipment to be realized by the user is expressed by the voice command information so as to realize that the electric equipment is controlled to execute corresponding operation according to the content. In addition, it should be noted that when the current electrical equipment does not enter the correct power-on process or the power-on operation fails to report, the IO port B of the power management unit of the main control module of the current electrical equipment remains in the low-level state, that is, it indicates that the main control module of the current electrical equipment does not enter the power-on state, and remains in the standby state.
Illustratively, taking an intelligent television as an example, a preset starting verb is a small dimension and a small dimension, when a user gives a target voice signal that is the small dimension and the user wants to watch a movie, a voice acquisition module identifies the target voice signal and divides the target voice signal into two parts, starting information and voice command information, wherein the starting information part is the small dimension and the voice command information part is the movie, after identifying that the starting information part is matched with the preset starting verb, the intelligent television is controlled to enter a startup process, a low level is sent to an IO port A of a power management unit of a main control module of the intelligent television, the voice command information part is stored, after confirming that the intelligent television correctly enters the startup process, an IO port B of the power management unit of the main control module of the intelligent television is set to a high level, and the voice acquisition module sends the content of the voice command information part to the main control module, the main control module controls the intelligent television to execute corresponding operation according to the specific functional content, expressed by the voice command information, of the intelligent television required by the user, namely, the intelligent television is controlled to start a movie selection interface for the user to select a movie or directly continue playing the movie which is not played last time in the history playing record.
According to the embodiment of the invention, the target voice signal containing the starting information and the voice command information is received, the starting information is identified to be matched with the preset starting word, the starting signal is sent to control the electric equipment to be switched to the starting state from the current standby state, the electric equipment is controlled to execute the corresponding operation according to the voice command information when the starting response sent by the main control module is received, the problems that the electric equipment in the standby state cannot be woken up by far-field voice in the prior art and further cannot be controlled by far-field voice in the whole process of the electric equipment are solved, the electric equipment in the standby state is woken up by voice, and the effect of saving the standby power consumption of the electric equipment is achieved.

if the fact that the audio and/or video information corresponding to the voice sequences is not stored locally is determined, request information containing the voice sequences is sent to a cloud server;
and when receiving the recognition results corresponding to the plurality of voice sequences, which are fed back and output by the cloud server, wherein the recognition results can be the audio and/or video information corresponding to the plurality of voice sequences, playing the audio and/or video information.
Specifically, the main control module preprocesses the voice command information to obtain a pure voice sequence, and performs further voice recognition on the voice sequence locally or on a cloud server. If the voice sequence is formed by a simple voice sequence, the local server can perform direct voice recognition, obtain a response or a resource corresponding to the voice sequence, and send the response or the resource to the electrical appliance control system to control the electrical appliance to execute corresponding operations according to the response or the resource, for example, entering a signal source or related resources related to the electrical appliance.
