Voice Interface

A user interface that accepts spoken language as input and typically provides audio output, enabling hands-free, eyes-free interaction with technology. Voice interfaces are used in voice-activated personal assistants, smart speakers, phone systems, and accessibility tools. For blind and low vision users, voice interfaces offer a natural way to interact without navigating visual layouts, but have limitations including difficulty with complex multi-step tasks, errors in speech recognition, limited feedback about system state, and challenges maintaining conversational context. Accessible voice interface design requires robust error handling, clear confirmation dialogues, natural language flexibility, and integration with other modalities for verification.
