MooLogue can be likened to the Duolingo of cow language—accessible enough for children, practical for farmers, and academically grounded for researchers. By merging playful design with scientific accuracy, it transforms casual listening into meaningful learning experiences.
The MooLogue sound library is the result of over 1,000 hours of field recordings collected from numerous Canadian dairy barns. Calls were recorded in key farm environments, including feeding stations, water troughs, hay areas, and milking parlors. Each sound has been meticulously categorized into emotional states and social contexts by a dedicated research team specializing in livestock bioacoustics. This rigorous process ensures that the sounds you hear are not only authentic but also scientifically significant.
In the barn, every sound carries meaning. By listening closely, we can gain a deeper understanding of the needs, emotions, and welfare of cows. MooLogue is a groundbreaking tool that transforms how farmers, researchers, and students engage with the voices of livestock.
