Summary

Carnegie Mellon University researchers from the School of Computer Science and Department of Psychology have demonstrated that spatial audio and Foley effects significantly enhance human engagement with AI agents. Their study, presented at CHI 2026 in Barcelona, involved creating an audio-only chatbot interface where participants perceived AI sounds from specific room locations and heard realistic sound effects like typing or pouring water. This approach aims to influence the development of audio-only AI systems for smart glasses and accessibility tools. The findings showed statistically significant increases in user engagement. Unexpectedly, participants began to expect the AI to adhere to human social norms, perceiving automated, non-contextual Foley effects as rude. Future work suggests making audio cues more context-aware to mitigate distraction, while maintaining engagement-boosting qualities independent of specific environments.

Key takeaway

For product designers developing audio-first AI interfaces or accessibility tools, this research indicates that incorporating spatial audio and realistic Foley effects can significantly increase user engagement. You should prioritize making these audio cues context-aware to align with human social norms, preventing users from perceiving non-contextual sounds as rude. Consider designing audio systems that maintain engagement without strict environmental dependencies.

Key insights

Spatial audio and Foley effects make AI agents feel more human, significantly boosting user engagement.

Principles

• Audio spatialization enhances perceived AI presence.
• Realistic sound effects (Foley) deepen immersion.
• Non-contextual audio cues can violate social norms.

Method

Researchers created an audio-only chatbot interface using spatialization to localize AI sounds and Foley effects (e.g., typing, pouring water) to enhance immersion, then tested user engagement via questionnaires.

In practice

• Integrate spatial audio into AI interfaces for engagement.
• Use context-aware Foley effects to avoid perceived rudeness.
• Design audio systems independent of specific environments.
