Whistled languages are unique forms of communication that use whistles to convey messages, often mimicking the sounds of spoken language. These languages are typically found in mountainous or forested regions where vocal communication can be difficult over long distances. Whistled languages can represent entire sentences or concepts, allowing speakers to communicate effectively without shouting. One of the most famous examples is Silbo Gomero, used by the inhabitants of La Gomera in the Canary Islands. This whistled language can cover distances of up to 5 kilometers and is taught in schools to preserve its cultural heritage.
