Virtual Assistants

Most smart devices now support Bluetooth 5.0. To drive better wireless connections between devices, Bluetooth SIG is going to release Bluetooth 5.2, which enables a better sound compression quality. To obtain authorized use of the Bluetooth® logo, vendors need to submit their products to BTQF to undergo a series of certification tests.  The highlights for voice-enables products are as follows:

1. RF (BLE RF-PHY)
2. Profile

For wireless products, remote control is essential to user experiences, and this is why Profile test is important. It is very common to see voice products suffer from AVRCP issues, which are failed synchronization between user actions and product performance.

Allion Bluetooth® RF Test System (ABRTS) allows customization of test cases.

According to the Wi-Fi Alliance, the five major test categories of Wi-Fi are connectivity, security, access, optimization, and application. Allion has silhouetted the following test cases for your voice products:

1. Wi-Fi 6 CERTIFIED n
2. WPA2
3. Wi-Fi Easy Connect
4. Wi-Fi Protected Setup (WPS 2.0)
5. Wi-Fi Direct

Since there are continuous transmitting and receiving of audio files when using audio products, QoS (Quality of Service) is an essential test case. Nearly 50% of products suffer from QoS issues, which are disruptions in the transmission priority between audio and video packet losses, eventually leading to poor sound quality.

According to Wi-Fi Alliance, the QoS should be prioritized as follows: sound, image, best-effort, and background monitoring data. We can assist vendors in conducting WMM tests so to ensure your audio and music quality.

Allion is authorized by Amazon as the ATL for Alexa Built-in. Alexa is Amazon’s cloud-based voice service available on more than 100 million devices from Amazon and third-party device manufacturers. With Alexa, you can build natural voice experiences that offer customers a more intuitive way to interact with the technology they use every day. Amazon offers a collection of tools, APIs, reference solutions, and documentation to make it easier to build for Alexa.

Allion currently provides testing and certification for “Alexa Built-in”, please contact with our Alexa Team for more details: service@allion.com
