detailed description

The disclosure is described below with reference to the drawings and embodiments.

FIG. 1 is a flowchart of a method for controlling an electrical device according to this embodiment. The method may be performed by the method for controlling an electrical device. The device may be implemented by software and / or hardware. For example, the device may be integrated. In electrical equipment such as televisions, it can also be applied to other electronic products with voice control functions. Referring to FIG. 1, the method in this embodiment includes the following steps.

In step 110, when a standby instruction is received, the state of the electrical equipment is determined.

The standby instruction may be sent by a user through a standby button of a remote control, and the user may also send voice information including a standby instruction to an electrical device to control the electrical device to switch the current mode to the standby mode.

The state of the electrical equipment can be a network state, and the network state can be determined by reading the network connection identifier. The network connection identifier can be obtained by calling a network detection interface function, and the network connection identifier can be set in advance. For example, if the obtained network connection identifier is "1", it can indicate that the electrical equipment is in a network connection state. The network connection identifier is "0", which means that the current network status of the electrical equipment is disconnected.

In step 120, the standby mode of the electrical device is selected according to the state of the electrical device, the standby mode includes a smart standby mode and a default standby mode. In the smart standby mode, the electrical device in the off-screen state has the ability to receive voice information and upload voice Information function.

Among them, the smart standby mode is a standby mode corresponding to the network in a connected state, and the default standby mode is a standby mode corresponding to the network in a disconnected state, that is, if the network status of the electrical device is connected, the smart standby mode is selected as the current standby Mode; or, if the network status of the electrical device is disconnected, select the default standby mode as the current standby mode.

The default standby mode is a standby mode preset before the electrical equipment leaves the factory. When the electrical equipment is in the default standby mode, only the standby indicator light is on, the main board of the electrical equipment is not working, and various functions of the electrical equipment, such as voice recognition, displaying images, and playing audio, are turned off.

Since the default standby mode function is relatively single, in this embodiment, a smart standby mode is added on the basis of the default standby mode. When the electrical device receives the standby instruction, if the current network of the electrical device is in the connected state, it enters the intelligent standby mode. At this time, you can control the standby indicator light by calling the standby application interface function, and turn off the backlight of the display, turn off the signal input, and turn off the sound channel, but leave the voice recognition channel to work normally to ensure that the user input voice can be received information.

In addition, whether it is the default standby mode or the smart standby mode, as long as a power-on instruction is detected, the display screen of the electrical device is turned on and various functions are turned on. The power-on instruction may be triggered by a user through a remote control, or the user may send a voice message including a power-on instruction.

Compared with the related art solution in which the electrical equipment cannot perform voice interaction with the user in the default standby mode, the technical solution of this embodiment can select the intelligent standby mode as the current standby mode according to the state of the electrical equipment, and in the intelligent standby mode, the electrical equipment The device can receive and upload the user's voice information to achieve corresponding operations based on the user's voice information in the standby state, improving the user experience.

In an embodiment, the standby mode of the electrical equipment can also be automatically switched over time. For example, when the electrical equipment is in the smart standby mode, it is detected whether the current time period is in a set time period; if it is in the set time period, , The smart standby mode is switched to the default standby mode. This setting can achieve the effect of saving power.

Among them, the set time period can be set to 12 pm and 6 am the next day. This setting takes into account that the user is generally in a rest state during this time, and the utilization rate of electrical equipment is low. Therefore, during this time , Can automatically switch the standby mode of the electrical equipment to the default standby mode. If the current time is not within the set time period and the electrical device is currently in the default standby mode, the current default standby mode can be automatically switched to the smart standby mode to wait for the user's voice input or remote control command input.

FIG. 2 is a flowchart of another method for controlling an electrical device according to this embodiment. In this embodiment, a step of performing voice recognition when the electrical device is in a smart standby mode is added to the above embodiment. The explanation of the same or corresponding terms in the examples will not be repeated here. Referring to FIG. 2, the method provided in this embodiment includes the following steps.

In step 210, when the standby instruction is received, the network status of the electrical device is determined.

In step 220, if the network state is the connected state, the smart standby mode is selected as the standby mode of the electrical device.

In step 230, when the electrical device is in the smart standby mode, if voice information is acquired, the voice information is pre-processed, and the pre-processed voice information is uploaded to the server.

The preprocessing of the voice information may include: performing enhanced processing and noise reduction processing on the voice information, and performing pulse code modulation on the processed voice information.

In one embodiment, after pre-processing the voice information, voice activity detection (Voice Activity Detection, VAD) can also be performed to obtain a pure voice sequence.

Exemplarily, since a large number of acoustic models and hundreds of thesaurus are stored in the server, the acoustic model and thesaurus can be used for semantic recognition of the speech sequence. Take the TV as an example, when the user sends "I want to watch XXX movie", the voice information can be obtained through the microphone array of the TV, and the internal analog-to-digital converter of the TV can convert the voice information into a digital signal, and then A processing module, such as a Digital Signal Processing (DSP) chip, can be used to pre-process the converted digital signal, and the pre-processed digital signal is packaged into a data packet and uploaded to the server. The server may be a cloud speech recognition server. The server can use technologies such as voice splitting, keyword extraction, and recognition to complete the analysis of the voice signal, and send the parsed voice command or the movie resource obtained according to the voice command to the television.

Exemplarily, if the voice sequence is composed of a simple voice sequence, voice recognition can be performed directly on the television locally to obtain the recognized voice command or the resource corresponding to the voice command.

In this embodiment, the collected voice information is uploaded to the cloud for semantic recognition, thereby reducing the calculation amount of local voice recognition and improving the accuracy of offline voice instruction recognition.

In step 240, the recognition result of the voice information by the server is received, and the electrical equipment is controlled to perform corresponding operations according to the recognition result.

In this embodiment, controlling the electrical equipment to perform a corresponding operation according to the recognition result is to enable some functions of the electrical equipment in the smart standby mode, such as a display function, audio and video playback functions, and the like. The activation of the above functions needs to be implemented with the hardware of the electrical equipment. For example, the level of the switch pin of the hardware module corresponding to a function to be activated can be set to a high level by calling a local hardware interface function, so that The hardware module can work normally to enable the functions that the hardware can achieve.

Exemplarily, controlling the current electrical equipment to perform a corresponding operation according to the recognition result may include the following steps.

If the recognition result is that the audio signal is played, the current off-screen state of the current electrical equipment is maintained and the audio playback function of the current electrical equipment is turned on to play the audio.

The voice recognition in this embodiment is performed when the electrical equipment is in a smart standby mode. In the smart standby mode, the voice function of the electrical device is turned on, while other functions such as the display function and audio playback are still turned off. If the recognition result of the voice information is the playback of audio signals, at this time, only the audio playback function needs to be turned on. In order to save power consumption, there is no need to turn on other functions, for example, it is not necessary to light up the display screen of the electrical equipment, that is, keep the electrical equipment off. Status and play the audio signal.

In an embodiment, if the electrical device is a television, when the television is in the smart standby mode, if the user sends a voice instruction to play audio, the television can be used as a speaker to play audio.

Exemplarily, if the recognition result sent by the server is a video signal, the display screen of the electrical device is turned on to enable the display function and play the video.

Based on the above embodiment, in this embodiment, in the intelligent standby state, the corresponding function of the electrical equipment is turned on according to the user's voice instruction, and the electrical equipment is controlled to perform the corresponding operation, without the need to first switch the electrical equipment to the on state and then Recognize the results and perform corresponding operations to achieve the effect of saving power consumption.

In one embodiment, the user can also control other smart home devices in the home by sending voice instructions to the electrical devices in the smart standby state, for example, they can control smart speakers, table lamps or air conditioners to switch modes, adjust volume, and so on.
