The Google ART Test, Google Assistant Readiness Test, is to use a set of standardized test procedures to verify that Google Assistant-enabled products can provide good performance while operating with voice. The test will check that the product has a low false rejection rate (FRR), word error rate (WER), and a low false awakening rate (FA). If it is described in simple terms, in the near-field and far-field environment, the Google Assistant can be woken up normally, and the speech recognition rate must reach Google's standard. This standard has the three dimensions mentioned above: FRR, WER, FA, KA1 The test results have reached this standard and some indicators are much higher than the standard line. This speech recognition rate is not only to correctly identify what you said, but also to de-reverberation, noise reduction, and echo cancellation, that is, not only to correctly identify what you said, but also to intelligently identify who should be heard., intelligently filter out the interference of other sounds.
To be able to achieve this standard, there are considerable requirements for the design capabilities of both hardware and software. The passing of this certification proves that we have the overall design capability of far-field voice control equipment in hardware and software. The passing of this certification also means that VIDEOSTRONG has new productivity. Based on KA1's technical accumulation and development experience, we can provide more customers with ODM services for smart voice-enabled smart terminal devices, such as smart speakers ODM.
The KA1 has been planned and designed since the beginning, and the certification application has been delayed for some objective reasons in the middle, but we have not continuously tackled key problems, optimized software and hardware design, built a standard testing environment, and more platform compatibility. Sub-commissioning and communication with platform vendors... etc. Until the opening of the certification application channel in the first half of this year, in September, we successfully completed the self-test of KA1, then sent samples for testing, and finally received the notification to pass the certification.
Thanks AI team for its hard work and continuous efforts, so that the company can take this as a lever to leverage the future full-smart hardware product chain.
