I confirm that all information provided is accurate, and I am conducting this experiment in a silent space with no external noise and wearing headphones.

📋 Instructions & Information for Participants:

• Wear headphones in a quiet environment with no background noise.
• Listen carefully to each audio clip and type exactly what you perceive.
• You can replay clips, adjust speed (0.50x–1.50x), or use up to 5 context clues if needed.
• Your session progress is automatically preserved at each trial; you can pause and resume at any time.
