Evaluation of the Appearance and Voice of Voice Guidance Characters

Character Design for Enhancing User Experience

Abstract

This study investigated how character settings in voice-guided beginner piano lesson software affect user motivation and impressions. Participants viewed lessons featuring male or female instructors and rated them on 13 items related to appearance, voice, and speaking style. Results suggest that female characters, regardless of the user’s gender, foster a more comfortable learning environment and encourage continued practice. Opposite-gender instructors enhanced psychological comfort, while same-gender instructors supported efficient learning. Tailoring character gender to user needs may enhance learning effectiveness and user satisfaction.
