Voice Assistant

A software application that uses speech recognition and natural language processing to respond to voice commands and perform tasks. Common examples include Amazon Alexa, Google Assistant, and Apple Siri. Voice assistants offer accessibility benefits for users who have difficulty with manual interfaces due to motor impairments, low vision, or limited digital literacy. However, they present challenges including speech recognition errors with non-standard accents, premature speech timeouts, privacy concerns, and difficulty with complex multi-turn conversations. Devices with screens (like Echo Show) can support users with hearing impairments through visual feedback.
