Learn how to leverage UserTesting to test voice-interactive devices and voice-user interfaces. |
This article applies to: UserTesting

About voice-interactive devices
- The Internet of Things (IoT) refers to any device that is connected to the Internet, including not only smartphones and computers but an array of connected devices found in places such as:
- Wearable tech
- Household items
- Infrastructure and development
- Healthcare
- Cars
- Retail
- With the rise of voice-enabled devices, more customers are experiencing frustration when VUI fails, such as misinterpreting voice commands.
- To ensure your VUI functions as intended for your customers, use UserTesting to validate your UX design, meet customer expectations, and optimize interactions. This helps drive adoption and improve the overall experience.
- Additionally, with the ability to now store native video and audio files safely and securely, the level of feedback and insights is limitless.
- For more information on native video and audio file storage, please see "Native video and audio testing."
Leveraging testing, you can discover the following insights:
- Understand customers’ expectations for a variety of voice-interactive devices (and then focus designs to meet those expectations)
- Learn what phrases customers typically use with VUI
- Error correction and prevention around phrasing or other VUI features
- Impact of accents and other regional/geographic nuances
- Impact of visual cues within VUI and their expectations
Templates
- We have created several templates in our template library that will give you a head start on creating your tests and asking helpful questions.
- These will help you troubleshoot voice-interaction pain points and identify evolving consumer needs.
- Some template options include:
Insights from testing
- To gather the most valuable human insights for your VUI device, consider these key test themes.
- There are sample questions from each category that you can ask contributors or your team during VUI development.
Testing for usability
- Does the VUI system need to log and/or store all events?
- Is the data display working properly?
Testing for security
- Is the user interface password-protected? How should that function?
- Is the data encrypted/protected during device transfers, apps, etc.?
Testing for connectivity
- What concerns do you have in connecting your device to the internet?
- Are the directions to connect your device understandable?
Testing for performance
- If five or more users use their devices simultaneously, will the system support that number without slowdown or worse?
- Is the device system scalable for your home? Office, etc.?
Testing for compatibility
- Is your device dependent on internet speed?
- Could this affect the use of the device and its features, such as VUI?
- Does your device need specific, compatible products for proper connectivity?
Testing for pilot use
- The VUI works fine in our lab setting; but does it work in a customer’s home environment?
- At what distance from the device does it no longer detect someone’s voice?
Testing for regulatory compliance
- Does this VUI uphold regulatory compliances for your [healthcare, finance, etc.] industry?
Testing for upgrade considerations
- Is this new upgrade to the VUI still compatible with your customer's [hardware, software, app, OS, etc.]?
Best practices
- Provide a maximum of two to three VUI options at a time for customers to compare and provide feedback.
- Give customers a chance to listen to VUI options multiple times or view the options as text.
- Context is everything. Always be sure to provide your customers with real-life scenarios.
