HEARD-LE: An Intelligent Conversational Interface for Wordle

This study introduces an innovative approach to design an interactive audio-based platform for the popular word game, Wordle. Unlike conventional word games that heavily rely on visual elements, there is a lack of alternatives in audio-based formats, leading to limited accessibility and engagement for a broader audience. To address this gap, we propose an audio-based game that transforms the traditional Wordle interface into a conversational format, exploring the possibilities of purely audio-based interactions. To justify design decisions for the proposed interface, we conducted a design study focusing on interaction cues between two players engaged in the Wordle game through conversation. Based on the insights obtained, we implemented the audio-based system. Subsequently, a user study was conducted to compare different input types (e.g., letter-based partitions, entire words) and evaluate the integration of an interactive question-based interface. Four distinct game variations were created for systematic evaluation, measuring mental/physical workload, enjoyability, and system intuitiveness. This research contributes to the development of inclusive and engaging audio-based word games, while providing insights into the benefits and challenges of incorporating interactive interfaces. It paves the way for a more accessible gaming experience and promotes the adoption of audio-based gaming interfaces in the broader gaming community.
