Voice User Interfaces (VUI) are among the latest advancements in accessibility, allowing visually impaired users to navigate websites and apps using only their voice and hearing. These interfaces also benefit individuals who need hands-free interaction, such as those cooking, driving, or multitasking.

For conversational VUI, consider the following recommendations:

• Keep messages concise: Shorter audio responses improve comprehension and efficiency.
• Allow interruptions: Users should be able to stop or skip messages when needed.
• Provide speech rate control: Adjusting the speed ensures better usability for different preferences.
• Ensure easy discoverability: Users should quickly find and activate voice interaction features.
