Voice User Interface (VUI)
A Voice User Interface (VUI) is a system that allows users to interact with technology through spoken commands or responses. In the context of form builders, VUI means respondents speak their answers into a microphone instead of typing. Unlike full conversational AI systems (Alexa, Siri), form VUI focuses on capturing structured input — transcribing spoken responses into form fields. Anve Voice Forms implements VUI through the W3C Web Speech API, providing browser-native speech-to-text for form input in 50+ languages with no app installation.
