Abstract
According to the wake-up and front-end algorithm interface provided by the solution provider, the wake-up callback message of the wake-up module is uploaded to the application layer through the uplink message communication module. After the recording data module receives the command to read the recording data from the application layer, it clears the history buffer, obtains the current recording data and transmits it to the upper application. The function setting module converts the operation commands of the upper application through the setting attribute interface of the hardware abstraction layer and then transmits them to the software and hardware device for function setting, and the status change message after setting is also reported to the application through the uplink message communication module. The present invention is used for universal system adaptation of the wake-up and front-end algorithm units provided by the underlying solution provider, shields the difference between software algorithms and DSP algorithm solutions, and incorporates all functions involving wake-up and front-end algorithm units into a unified level of management. It is convenient for later maintenance and function expansion.
Description
technical field [0001] The invention relates to the field of smart home management, in particular to a general wake-up recognition algorithm management device and a management method located at a hardware abstraction layer. Background technique [0002] With the development of speech recognition technology and the wide application of smart home appliances, many smart devices now have a voice wake-up function. Users only need to say the preset wake-up word to wake up the smart device without manual operation by the user. [0003] However, since various device interfaces do not have a unified management module, wake-up and recognition are done at the application layer. The hardware abstraction layer only provides recording data, and the application layer transmits the recording to the server algorithm library, and the wake-up and recognition results are obtained through the application layer. , requires multi-level joint debugging of bottom-layer and upper-layer applications, ...
