👉 Cavillers are a group of people who have been recognized as having a unique ability to make noises that sound like laughter, but they cannot actually laugh. This ability is often described by their "laughing voice" or "laughing sound," and it can be difficult for others to understand. Cavillers are known for their ability to mimic the sounds of laughter, but they do not have the same range or quality as a typical human laugh.
