Audio Matters Too: How Audial Avatar Customization Enhances Visual Avatar Customization

Bibliographic Information

• Field of Study: Character customization in digital games, player identity, and player experience
• Keywords: games, character customization, audio, voice, player experience, identity, intrinsic motivation

Research Background and Problem Statement

• What problems or challenges did the authors identify?

  • While character customization has been proven to effectively enhance player experience, existing research has almost exclusively focused on visual customization, neglecting the potential of audio customization.
  • Voice-related features in games are often considered non-core content and involve high deployment costs (e.g., multilingual dubbing and localization), leading to relatively little research and development in this area.

• Why is this problem important?

  • With advancements in artificial intelligence technologies (e.g., voice synthesis and cloning), the feasibility of incorporating audio customization into games has significantly increased.
  • Understanding the impact of audio customization on game experience, player identity, and interaction behaviors not only aids in improving game design but could also extend to applications in virtual reality, online education, and other fields.

• Research Motivation and Related Work

  • The authors reviewed the positive effects of character customization on players' intrinsic motivation, game immersion, and loyalty.
  • Previous studies have shown that character voice can enhance relatedness, recognition, and trust, but there is a lack of systematic research on the effects of character voice customization.
  • This study aims to fill the gap in existing research by validating the effects of audio customization through large-scale experiments.

Proposed Solution

• What methods or solutions did the authors propose?

  • The authors designed a 2 × 2 experiment (visual selection vs. visual assignment; audio selection vs. audio assignment) to explore whether audio customization can match or enhance the effects of visual customization.

• What is innovative about this solution?

  • This is the first systematic study of the impact of audio avatar customization on player behavior and psychology.
  • The research simultaneously examines the interaction effects of audio and visual customization and introduces large-scale pre-registered experiments to ensure the reliability of results.

• What are the implementation steps and key technologies used?

  • The authors developed an educational programming game, "CodeBreakers," which includes character audio and visual customization options for the experiment.
  • Four character models and four audio options (matching two gender characteristics) were created to ensure quality and adaptability of both audio and visual elements.
  • A total of 1,526 participants were recruited via Amazon Mechanical Turk, and player experiences under different conditions were compared after controlling for variables.
  • ANOVA and parallel mediation analysis were used to evaluate the effects of customization options on player performance (e.g., time spent, intrinsic motivation) and attitudes (e.g., willingness to recommend).

Research Findings

• What specific findings were obtained?

  • Visual customization directly enhanced character identity and autonomy.
  • Audio customization had a positive impact on identity and autonomy only when visual customization was present.
  • Visual customization promoted game time, intrinsic motivation, immersion, motivation for future gameplay, and willingness to recommend. Audio customization amplified these effects.

• What advantages does it have compared to existing solutions?

  • The study provides preliminary evidence that audio customization enhances the effects of visual customization, highlighting the potential value of audio customization in improving player experience.
  • The experimental design was rigorous, ensuring high reliability and generalizability of the results.

• What were the experimental or evaluation results?

  • The effects of visual customization were significantly stronger than those of audio customization, but the latter enhanced the former's effects, especially in scenarios requiring character identity recognition.
  • Data indicated that audio customization positively influenced intrinsic motivation, immersion, and game time.

• Limitations and Future Directions

  • The audio customization options in this study were limited to two voice choices and did not explore more detailed audio attributes (e.g., pitch, rhythm).
  • The study focused on a single game (an educational programming game); future research should expand to other game genres and fields (e.g., virtual reality tools, learning applications).
  • Further research is recommended to investigate the impact of character audio customization on other player interaction behaviors, such as teamwork and multi-user voice environments.
