Wake-up rate test of smart speakers
Is it a structural problem that the smart speaker can't wake up? Or is it an algorithm issue? Or an angle problem? Or is it an environmental issue? Or is it a wake word problem?
What kind of algorithm is suitable for use in coffee shops, what kind of algorithm is suitable for use on the subway (issues that must be considered for the AI function of earphone implantation), and what kind of algorithm is suitable for use in the hotel lobby (issues that need to be considered for service robots); After the structure and algorithm are determined, what is the wake-up effect from various angles, what is the wake-up effect under various signal-to-noise ratio conditions, etc. To get the final answer to the above questions, you can only pass the test and verify.
Does the company have to recruit a lot of testers in the product development stage, conduct scene simulation, and conduct manual and inefficient testing? What kind of method can quickly and objectively, automatically, and quantitatively test the above questions, and Megaxin is here to help you find the answer.
Solution:
Two aspects need to be checked
A. Acoustic indicators test
Including microphone array frequency response, distortion, acoustic isolation, structural resonance, etc. Although MegaSign has a complete solution and has rich experience in project combat, this is not the focus of today's discussion. Interested friends, you can pay attention Check out previous information on our public account.
B. Wakeup Rate Test
It is a functional test, the focus of this article, please see the following video introduction for details
1.Environment construction
2.Test sequence explanation
3.Actual operation effect
We dealt with the first wake-up word, deliberately making it impossible to wake up from an angle, so that everyone can experience the software effect.
Conclusion:
Whether it is smart speakers, smart cars, smart headphones, smart robots and other smart devices, the interface of choice for human-computer interaction is voice. In this emerging industry, no matter you are a brand owner, an OEM, or a solution provider Even for chip manufacturers, the wake-up success rate of your product will directly determine your success or failure. An objective, comprehensive, detailed and quantitative test and evaluation of a product is a necessary condition for success. There is no shortcut, and MegaSign will always be there On this road to success, we will accompany you who are pursuing quality and dreaming about the future, and provide you with audio testing instruments and systems from R&D to mass production.
