Communicating with animals has fascinated humans for centuries. While full conversations are not yet possible, scientists use technology and behavioral studies to better understand animal signals. AI algorithms analyze sounds and patterns in dolphin clicks, bird songs, and primate calls. Progress is being made in interpreting emotions and intentions, bridging the gap between species. This research has implications for animal welfare, conservation, and understanding cognition. Although a universal animal language remains elusive, growing knowledge enriches our relationship with the natural world.
