Voice Content and Usability

For millennia, humans have relied on spoken language, but recent advances have introduced voice interfaces that require machines to navigate the complexities of human speech. Voice interactions mirror human conversations, encompassing transactional (for outcomes), informational (for knowledge), and prosocial (for connection). Transactional voice interactions are direct and efficient, while informational interactions are more exploratory and informative. Voice interfaces can be either pure (entirely spoken) or multimodal (with visual support). Interactive voice response (IVR) systems have become commonplace, but they can be clunky and frustrating. Screen readers, designed for visually impaired users, provide a voice-based alternative for web interaction but can be verbose and challenging to use. Voice interfaces offer potential advantages over screen readers, but they also present unique design challenges. As voice interfaces evolve, designers must consider the nuances of human speech and the diverse needs of users.
