Languages communicated by whistling are relatively rare, but are known from around the world. One example is the Silbo on the island of La Gomera in the Canary Islands, which maintains Spanish's five vowels, but reduces its consonants down to four. Others exist or existed in all parts of the world including Turkey (Kusköy "Village of the Birds"), France (the village of Aas in the Pyrenees), Mexico (the Zapotecs of Oaxaca), South America (Pirahă), Asia (the Chepang of Nepal), and New Guinea. They are especially common and robust today in parts of West Africa, used widely in such populous languages as Yoruba and Ewe. Even French is whistled in some areas of western Africa.
In continental Africa, speech may be conveyed by a whistle or other musical instrument, most famously the "talking drums". However, while drums may be used by griots singing praise songs or for inter-village communication, and other instruments may be used on the radio for station identification jingles, for regular conversation at a distance whistled speech is used. As two people approach each other, one may even switch from whistled to spoken speech in mid-sentence.
In the Greek village of Antia, the entire population knows how to whistle their speech, and whistled conversations are also carried on at close range.
As the expressivity of whistled speech is limited compared to spoken speech, whistled messages typically consist of stereotyped or otherwise standardized or set expressions, are elaborately descriptive, and often have to be repeated. However, in languages which are heavily tonal, and therefore convey much of their information through pitch even when spoken, such as Mazatec and Yoruba, extensive conversations may be whistled.
In Africa and indigenous Mexican communities, whistled language is used only by men.
Whistled languages are normally found and used in locations with abrupt relief created by difficult mountainous terrain, slow or difficult communication (no telephones), low population density and/or scattered settlements, and other isolating features such as sheepherding and cultivation of hillsides (ibid: 27–8). The main advantage of whistling speech is that it allows the speaker to cover much larger distances (typically 1–2 km but up to 5 km) than ordinary speech, and this is assisted by the relief found in areas where whistled languages are used. In practice, many areas with such languages work hard to preserve their ancient traditions, in the face of rapidly advancing telecommunications systems in many areas.
A whistled tone is essentially a simple oscillation (or sine wave), and thus timbral variations are impossible. Normal articulation during an ordinary lip-whistle is relatively easy though the lips move little causing a constant of labialization and making labial and labiodental consonants (p, b, m, f, etc.) impossible (ibid: 3). "Apart from the five vowel-phonemes — and even these do not invariably have a fixed or steady pitch — all whistled speech-sound realizations are glides which are interpreted in terms of range, contour, and steepness." (ibid: 8)
In a non-tonal language, segments may be differentiated as follows:
- Vowels are replaced by a set of relative pitch ranges
- Stress is expressed by higher pitch or increased length
- Consonants are produced by pitch transitions of different lengths and height, plus the presence or absence of occlusion. ("Labial stops are replaced by diaphragm or glottal occlusions.")
In the case of Silbo Gomero, such strategies produce five vowels and four consonants.
Though whistled languages are not secret codes or secret languages (with the exception of a whistled language used by ńańigos terrorists in Cuba during Spanish occupation (ibid: 22)), they may be used for secretive communication among outsiders or other who do not know or understand the whistled language though they may understand its spoken origin. Supposedly, in Aas during World War II farmers were nearly caught watering down their milk but police were unable to find any evidence as the farmers were warned by whistled messages of the police approaching and were able to prepare. There are similar stories of La Gomera (ibid: 15).
