Whistled language is a whistling-based communication system developed in Kuşköy, a village in the Çanakçı district of Giresun province in Türkiye’s Eastern Black Sea Region. This system is used for human communication, taking advantage of geographical conditions that facilitate the transmission of sound waves across slopes and valleys. Whistled language relies on a sound transmission system in which syllables of Turkish words correspond to specific whistling frequencies. The intonation, duration, and pitch variations of spoken Turkish are converted into whistles.

Whistled language emerged historically from the need to communicate across the region’s mountainous terrain and remote settlements. The tradition of this communication method has been passed down orally from generation to generation. Whistled language was not only practiced in Kuşköy, Giresun, but also in various local forms across different parts of the Black Sea region in the past. However, today Kuşköy remains the primary location where the language is intensively used.
In Turkological studies, the term “whistled language” has historically been used to refer both to whistling as a communication medium and to secret spoken forms of communication. Ottoman-era sources indicate that it was recognized as one of the secret languages formed by adding sounds to syllables. In this context, the concept of “whistled language” encompasses alternative communication methods established through whistling as well as phonological transformations.
Whistled language is a system based on the phonological units of Turkish. Each letter or syllable is represented by a distinct whistle tone, duration, or frequency. Users of the whistled language can distinguish between phonemes by altering the direction and intensity of the whistle. In practice, high and low pitch whistles correspond to various vowels and consonants in the language.
The structure of this language is based on the adaptation between the acoustic properties of the human voice and natural environmental conditions. In mountainous terrain, a whistle can be transmitted over several kilometers. As a result, users of whistled language can clearly convey messages across valleys, fields, and forested areas.
The Turkish alphabet consisting of 29 letters forms the basis of whistled language instruction. The whistle equivalent of each letter is determined by breath volume, tongue position, and lip opening. Educational programs teach the production of specific sounds such as ö, ü, ı, and i with distinctive emphasis. Through this method, words are transmitted as sequences of whistle frequencies.

Whistled language is an integral part of social life in Kuşköy, located in the Çanakçı district of Giresun. It has been used for daily tasks, communication between fields, calls between houses, and the transmission of news. This form of communication served as an alternative medium to spoken Turkish.
Whistled language has been preserved as a component of the region’s collective memory. The local population learns the language from childhood and continues its practice alongside local traditions. Annual festivals feature whistled language performances, and efforts are made to transmit it to younger generations.

In 2017, whistled language was inscribed on UNESCO’s List of Intangible Cultural Heritage in Need of Urgent Safeguarding. This recognition affirmed its status as a cultural heritage at risk on the international stage.
As part of conservation initiatives, courses have been launched in community education centers, and specialized teaching materials for whistled language instruction have been developed. At Giresun University, “Whistled Language” has been introduced as an elective course in the curriculum. In addition, academic research has been initiated to systematically document the language by developing a standardized alphabet.
Scientific studies on whistled language examine the relationship between the physical properties of sound waves, the human auditory system, and linguistic structures. Under projects supported by TÜBİTAK, acoustic analysis of whistled language has been conducted and audio data has been recorded. These studies have demonstrated that the brain processes whistled language similarly to spoken language.
Local authorities, civil society organizations, and educational institutions collaborate to sustain the culture of whistled language. Events in Kuşköy include instruction and promotion of the language, and demonstrations are offered to visitors within the framework of cultural heritage tourism. Following UNESCO’s inscription, the Giresun Provincial Directorate of Culture and Tourism launched promotional projects for the region.
Whistled language holds a significant place in regional tourism as one of the defining elements of Giresun’s cultural identity. Every year, the “Whistled Language Festival” is held in Kuşköy, featuring whistling performances, exhibitions, and workshops. These events provide visitors with opportunities for cultural engagement.

Under tourism initiatives, infrastructure improvements have been made in Kuşköy, and local residents have been actively involved in guiding and cultural promotion activities. The sustainability of whistled language culture is supported through these promotional and educational efforts.
With the widespread adoption of modern communication tools, whistled language is now used less frequently in daily life than in the past. Nevertheless, thanks to its UNESCO inscription, university courses, and local festivals, it has entered a process of revitalization. Whistled language is regarded as an important means of communication for preserving cultural identity and sustaining community solidarity.
