Hardware access:
First, connect the voice wake-up chip to the main controller or processor according to its specifications and interface requirements. This usually involves connecting the pins of the chip to the corresponding pins of the motherboard, as well as connecting the power supply.
Configuration and initialization:
At the software level, you need to write the corresponding driver or software library to communicate with the voice wake-up chip. These drivers or software libraries are responsible for configuring and initializing the chip, setting the wake-up word (the wake-up word is a specific vocal vocabulary set by the user to wake up the device), and communicating with the main controller.
Set the wake-up word:
During the initialization process, you need to set the wake-up word of the device. The wake-up word is a set of specific vocal vocabulary. When the voice wake-up chip detects these vocabulary, it will trigger a wake-up signal, waking the device from a sleep or low-power state.
Start the wake-up function:
After the initialization is complete, start the function of the voice wake-up chip. This usually involves setting appropriate parameters and configurations to ensure that the chip can work properly and accurately identify the wake-up word.
Standby/sleep mode:
When the device is in standby or sleep mode, the voice wake-up chip will continuously listen to the sounds in the environment and detect the presence of the wake-up word. Once the wake-up word is detected, the chip will trigger a wake-up signal and send a wake-up event to the main controller.
Perform the corresponding operation:
Once the device is successfully awakened, the main controller can perform the corresponding operation, such as starting the voice assistant, playing a prompt tone, and executing user commands.
In general, using the voice wake-up chip requires reasonable settings and configurations to ensure that it can accurately identify the wake-up word and wake up the device reliably and stably. At the same time, corresponding integration and development are required at the software level to achieve the full use of the voice wake-up function.
