As shown in fig. 3, a second embodiment of the present invention provides an intelligent device, where the intelligent device includes: the device comprises a voice acquisition device 103, a wake-up chip 102 and a main control chip 101;
the voice acquisition device 103 is connected to the wake-up chip 102, and is configured to acquire first voice information and send the first voice information to the wake-up chip 102;
the wake-up chip 102 is connected to the main control chip 101, and is configured to receive the first voice information, perform recognition analysis on the first voice information, generate a wake-up notification when the first voice information includes a preset voice instruction, and send the wake-up notification to the main control chip 101;
and after receiving the awakening notification, the main control chip 101 awakens the control function of the intelligent device.
In this embodiment, the voice collecting device 103 may be connected to the wake-up chip 102 through buses such as I2S, PCM, TDM, PDM, and the like, so as to send the collected voice information to the wake-up chip 102, the wake-up chip 102 may also be connected to the main control chip 101 through buses such as I2S, PCM, TDM, PDM, and the like, so as to forward the voice information collected by the voice collecting device 103 to the main control chip 101 when the main control chip 101 needs the voice information, and meanwhile, communication between the wake-up chip 102 and the main control chip 101 may also be implemented through communication protocols such as UART, GPIO interrupt, SPI, I2C, and so as to send the wake-up notification generated by the wake-up chip 102 to the main control chip 101 through communication modes such as UART.
Preferably, in this embodiment, the voice collecting device 103 is connected to the wake-up chip 102 through an I2S bus, and the wake-up chip 102 is connected to the main control chip 101 through an I2S bus. At this time, any end of the I2S bus between the voice capture device 103 and the wake-up chip 102 may be selected as a master, and the main control chip 101 may be selected as a master between the main control chip 101 and the wake-up chip 102, so that when the main control chip 101 is in a low power consumption state without being woken up, the main control chip 101 does not output a clock, thereby preventing the wake-up chip 102 from outputting unnecessary data.
When the intelligent device is in a standby state, the main control chip 101 enters a low power consumption state, the voice acquisition device 103 is turned on to acquire first voice information in real time, and the acquired first voice information is sent to the wake-up chip 102, and the wake-up chip 102 is also turned on to receive the first voice information sent by the voice acquisition device 103 and perform recognition analysis on the first voice information.

The preset voice instruction may be an awakening instruction that only awakens the smart device, such as "jingle", and of course, the preset voice instruction may also be a local control instruction that executes a corresponding operation on the smart device, such as "play music", "reduce volume", "next", and the like. When the preset voice instruction is a 'jingle' awakening instruction, only awakening the intelligent equipment; when the preset instruction is a local control instruction of 'playing music' or 'reducing volume', the intelligent device is awakened firstly, and then music is automatically played based on the control instruction of 'playing music', or the volume of the intelligent device is reduced based on the control instruction of 'reducing volume', and the like. It is understood that the preset voice wake-up command can be preset by the user according to actual needs, for example, a special word such as "the saint equalling heaven" can be set as the wake-up command.
Optionally, the wake-up chip 102 includes a cache unit 305, where the cache unit 305 is configured to store third voice information acquired by the voice acquisition device 103, and send the third voice information to the main control chip 101, and the main control chip 101 sends the received third voice information to a cloud server, and executes corresponding operation on the smart device according to an analysis result returned after the cloud server analyzes and processes the third voice information.
That is, after the preset voice instruction is a wake-up instruction and wakes up the smart device, and when the voice acquisition device 103 further acquires third voice information, the voice acquisition device sends the acquired third voice information to the wake-up chip 102, and the wake-up chip 102 stores the third voice information in the cache unit 305. After the smart device is awakened and the cloud server is triggered in a wireless manner such as bluetooth, the main control chip 101 may acquire the third voice information from the cache unit 305 and send the third voice information to the cloud server in a wireless manner such as bluetooth, the cloud server analyzes the third voice information and returns a corresponding message to the smart device according to an analysis result, and the smart device executes a corresponding operation based on the corresponding message.

As shown in fig. 4, the intelligent device includes a voice acquisition apparatus 103, a wake-up chip 102, a main control chip 101, and a digital signal processor 204.
In this scenario, the voice collecting device 103 is connected to the digital signal processor 204, and the voice collecting device 103 is configured to collect first voice information and send the first voice information to the digital signal processor 204.
The digital signal processor 204 is configured to pre-process the received first voice message, and meanwhile, the digital signal processor 204 is further connected to the wake-up chip 102 to send the pre-processed first voice message to the wake-up chip 102.
The wake-up chip 102 is further connected to the main control chip 101, and is configured to receive the first voice information preprocessed by the digital signal processor 204, perform recognition analysis on the preprocessed first voice information, generate a wake-up notification when the recognition analysis shows that the preprocessed first voice information includes a preset voice instruction, and send the wake-up notification to the main control chip 101.
