Description
Technical Field
The invention belongs to the technical field of artificial intelligence, relates to a voice recognition product development technology, and particularly relates to a local voice recognition module production testing method.
Background
The voice recognition control technology can improve the experience of product control, and is gradually used in various products at present. Especially, with the appearance of the intelligent voice chip of the terminal, the voice recognition can be realized through the voice recognition module loaded with the intelligent voice chip, the voice recognition and control can be realized without being connected to a cloud server, the dependence of the equipment control on the network can be removed, and the real-time performance and the recognition effect of the control can be guaranteed to the maximum extent, so that the intelligent voice chip of the terminal gradually becomes a main scheme of the voice recognition control.
The local voice recognition chip needs to load a voice recognition module in the equipment, and because voice products are diversified and voice control command words of different product types are different, software and firmware in the voice recognition module can be modified according to different products. Generally speaking, the capacity of the voice recognition software firmware is large, and the voice recognition software firmware is placed in a Flash memory built in a voice recognition chip inside the voice recognition module or a Flash memory chip externally connected with the voice recognition chip inside the voice recognition module.
When testing a local voice recognition chip, the general practice in the prior art is to store and burn a corresponding product test software firmware in a Flash memory in a voice recognition module to be tested, download a corresponding test program into test equipment, run the corresponding test program by the test equipment to play a corresponding test command word, send the test command word to the voice recognition module to be tested, feed back a result after the voice recognition module recognizes, and judge whether a module recognition function is correct and whether the burned software firmware is correct according to the result.
Because the command words of different products may be partially repeated, the same command word needs to be tested multiple times to distinguish different firmware during testing, thereby increasing the testing time cost of the module. Meanwhile, the voice recognition module often encounters a plurality of upgraded versions of firmware with the same command word but different command word confidence degrees, and at the moment, the old and new versions of firmware are difficult to distinguish by using a common test method, so that a module processing factory is easy to confuse the firmware with different versions and deliver the firmware, and extra loss and time waste are caused to product manufacturers. Finally, when different firmware is burned in the same module, the test program of the same module is different in terms of test command words, and therefore, when the module is used for mass production test, particularly when different firmware modules are tested at the same time, the test program in the test equipment needs to be frequently replaced, time waste is caused, and the situation that test problems are caused due to errors caused by manual replacement of the test program is easy to occur.
