Why do we need Allion?

Audio and video complement each other, and both are equally important. With more than 20 years of experience in audiovisual product validation, along with the newly launched AI Robotic Testing, Allion is capable of assisting vendors in identifying critical problems of the products, which will significantly reduce the possibility of product returns and feedback of unfavorable consumer experience.

1. Comprehensive testing solutions that integrate various audiovisual technologies

Allion integrates audio and visual technological integration, including HDMI, HDR, DisplayPort, USB Type-C Audio testing to provide consumers with one-stop solution for the products’ functionalities, as well as software and hardware integrations.

2. Integrate rich and diverse voice data and device database across different industries and markets

In addition to obtaining massive voice database for big data analysis, voice recognition also needs to be tested on various products, including wearable devices and smart devices for interoperability testing. Allion continues to establish huge voice database and regularly purchases devices spanning across the five continents to ensure the smart products are interoperable with each other, thereby building a complete and harmonious ecosystem.

3. Field testing that validates the actual performance of voice

We can simulate real-world user behaviors and validate our products’ actual voice performance.

Service Targets:

1. Various audio devices include

  • AV receiver: microphones
  • AV player: speakers, built-in speaker of devices, and headphones
  • AV receiver and player: such as micro speakers, smart speakers, smart robots, etc.
  • Connector: phone jacks
  • Various device systems: smart TVs, teleconference systems, computers, laptops, cell phones, keyboards, mouse, etc.:

2. Customers who are planning to build its own test facility for AVS Self-Test

 

Scope and test items of audio and acoustics validation

1. Electroacoustic Testing

The main purpose of Electroacoustic Testing is to measure the quality of electroacoustic and ensure the source signal is not distorted, such as testing the sending and receiving of laptops and speakers.

2. Voice Recognition Testing

Voice assistant integrates various functions, such as AI, voice recognition, and wireless technologies. As voice recognition gets more diverse, product validation also gets more complex. Allion is able to execute relevant voice recognition validations, including functionality, usability, acoustics performance and interoperability of popular products such as Alexa for PCs Certification, Amazon Self-Test, cortana Self-Test, Intel SST Platform, etc.

3. Noise Testing

Allion is able to customize noise testing for consumers, and find out the abnormal noise level generated by customer’s products under specific frequency band so as to be used by consumers as the basis for carrying out product improvement.

4. ITU-T Testing

ITU-T, or International Telecommunication Union, Telecommunication Standardization Sector of ITU, is an organization set up by the United Nations for establishing telecommunication standard. The two standards, P1100 and P1110, are standard criteria for hands-free speakers in cars. Allion has established complete testing standards to ensure the dashboard head unit is able to operate normally and maintain a certain level of quality under hands-free condition.

5. Simulation Test—User scenarios

Even if the product has passed the basic validation in user scenario testing, there may be many issues in actual complex usage scenario, resulting in significant decrease in customer satisfaction. Allion provides user scenario based testing, where voice validation is carried out by simulating user behaviors through different scenarios and field conditions.

6. AI Robotic Testing

Allion’s AI Robotic Testing is a combination of deep learning, visual recognition, automation, and data collection and analysis, and is able to automate massive and repetitive validation steps, such as pairing Bluetooth speakers with cell phones to check whether they are interoperable with each other, thus providing consumers reliable and accurate test results qualitatively and quantitatively.

7.Alexa Self-Test Lab Establishment New Launch

Alexa is booming as Amazon announced that it has sold 0.1 billion of Alexa-enabled devices and the numbers of suppliers has also reached 4500. Up to now, Alexa devices include voice assistants, smart air conditioners, smart kitchen hoods, smart wine cabinets, smart microwaves and smart plugs and more other devices are under development.

Allion foresees the thriving market in Alexa so launches an efficient and cost-effective solution for AVS (Alexa Voice Service) developers who are planning to build its own testing capability of Alexa Self-test. Our new launched solution will help customers to ensure every Alexa device’s performance by building test facilities (an environment and equipment) with full education training.

Service Scope for Alexa Self-test Lab

8.Alexa For PCs Certification New Launch

“Alexa For PCs” is a qualification for Windows 10 PC devices to adopt Alexa voice services. Users are able to give commands to other smart devices via their computers, including desktop, laptops, AiO, and tablets.

Allion Labs is authorized by Amazon to offer “Alexa For PCs” Certification. Vendors can engage in self-test and certification tests, including stability test and acoustics tests at Allion to accelerate the launch time of your products to the market.

Alexa Built-in

Alexa Self-test and Certification Test at Allion Labs

Allion is an Authorized Test Lab for Alexa. You can work directly with us and utilize our lab to test and submit your product for certification. During the test, we will use test automation and a series of checklists provided by Amazon to ensure that your product meets acoustics, music, functional, and user experience (UX) requirements. We will also generate certification test results in the form of Alexa Qualification Tool (AQT) reports and manual checklists, for submission to Amazon.

 

Testing environment

As noise from surrounding environment can easily interfere with the product’s audio function, Allion has invested a huge amount in building various types of low-noise testing environment, including Anechoic Test Chamber and Acoustic Test Chamber, which are able to control noise interference to simulate user scenarios, and effectively identify the source of interference affecting the product through validation methods.

1.Anechoic Test Chamber
2.Acoustic Test Chamber

 

Audio Testing Equipment

1.ITU-T ACQUA

Allion has adopted a testing equipment to carry out the test criteria by the ITU-T. This equipment provides a full loop, as all DUTS will send their signals back to the main system, namely the ACQUA, and conduct further analysis on the call qualities.

2.Audio Precision

The audio precision is designed to measure the quality of Electro-acoustic while making sure that the signals are not distorted.
