Smart Voice Assistant Technology & How To Test It

Voice assistance technology is becoming increasingly popular in homes and businesses around the world. From Alexa to Google Home, consumers are now able to access and control their home electronics, search the web, and more with just their voice. With the rapid growth of this technology, however, comes the need for rigorous testing to ensure accuracy, reliability, and security.

Testing is essential to ensure that voice assistance technology is performing as expected, providing accurate responses, and not compromising user privacy. Testing can help in identifying potential areas of improvement, such as natural language understanding and speech recognition accuracy. By running tests, developers can ensure that voice assistance technology is reliable and secure and that users can trust the answers they receive. Ultimately, it’s testing that helps to ensure that we can all enjoy the convenience, simplicity, and accuracy of these powerful technologies.


What is a Smart Voice Assistant?

Getting operations or activities done using voice commands is called voice assistance. A voice assistant is a digital assistant that uses voice recognition, language processing algorithms, and voice synthesis to listen to specific voice commands and return relevant information or perform specific functions as requested by the user.

Smart voice assistant technology is broadly popular nowadays. Many big companies like Apple (Siri), Microsoft (Cortana), Amazon (Alexa), and Google have their own voice assistants. Users all over the world are now able to send commands using a voice which makes the task easier and faster to execute.

The following graph shows that in what environments people are using Voice Commands.

Characteristics of Voice Assistant

The main characteristic that voice assistants offer is that they allow people to operate them hands-free, by using their voice. Some main characteristics include:


Performing basic chores like making phone calls, sending texts, setting up reminders & alarms, checking and updating you about weather, etc., with voice command. This makes them very useful for individuals having vision, mobility, and cognitive disabilities.


As a replacement for your fingers, they enable you to choose and launch programs, speak and type into text fields, send, tap, scroll, etc. People with disabilities that impede their dexterity, motor skills, or movement in their upper limbs can benefit from this function. This enables these folks to complete their work by using voice commands and speech recognition to operate their smart gadgets.


As a chatbot, it can simulate a conversation with a human user. Many companies are nowadays using them as customer service devices to interact with users like a human would and answer basic questions.


As a smart home assistant, it lets you control a range of connected devices in your home from your smartphone. As long as both your voice assistant and your phone are connected to the internet, you can control your lights, alarms, home appliances, security gates & cameras, etc.

How to Test Voice Assistant?

  • Unit Testing: The intended audience for this test is creators of voice-based applications. To make sure the code is operating properly in isolation, they must do unit testing. To avoid calling actual external services or accessing the cloud, which hosts the backend of the majority of voice apps, unit testing is focused on ensuring that your code and logic are sound.
  • End-to-End Testing: These tests are intended for QA teams. It makes sure that the AI, code, and external services are all operating properly. The tests have to be thorough, feasible, simple to develop, read, and maintain.
  • Continuous Testing (Monitoring): Targeted for Ops personnel, this kind of test verifies that the service operates faultlessly after deployment. This type of testing validates your voice-based software periodically. When the voice-based software has ceased to function as planned, a replacement should be simple to set up and produce results right away.
  • Usability and Performance Testing: In the case of voice assistant testing, Usability and Performance testing ensures that the app's AI components are functioning properly. Product Managers and developers are its intended audience. The main objective is to find problems with the assistant's and your app's speech recognition and NLU behavior.


Technology is advancing rapidly and to keep up with the same, it is important to ensure that business is utilizing up-to-date technologies. As voice assistance is being adopted by every age group in the world, its overall growth is only going to increase in the near future. Therefore, before launching any application, software, device, etc. that supports smart voice assistant technology, it is highly recommended to get it tested to provide the correct and accurate results to the end users. QASource is fully equipped with the professionals of QA analysts and up-to-date testing techniques to aid in providing the best user experience in voice assistance.
