Whistled language
Whistled languages differ according to whether the spoken language is
tonal or not, with the whistling being either tone or
articulation based. Tonal languages are stripped of articulation, leaving only
suprasegmental features such as duration and tone, and when whistled retain the spoken melodic line. In non-tonal languages, some of the articulatory features of speech are retained, though the normally
timbral variations imparted by the movements of the
tongue and
soft palate are transformed into
pitch variations. (Busnel and Classe 1976: v) Thus whistled languages convey
phonemic information solely through
tone, length, and, to a lesser extent,
stress, and many phonemic distinctions of the spoken language are lost. "All whistled languages share one basic characteristic: they function by varying the
frequency of a simple
wave-form as a function of time, generally with minimal dynamic variations (but see Cowan 1948 see
Mazateco), which is readily understandable since in most cases their only purpose is long-distance communication." (ibid: 32)
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 (
Pirahã), 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: 27â€"8). The main advantage of whistling speech is that it allows the speaker to cover much larger distances (typically 1â€"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 â€" and even these do not invariably have a fixed or steady pitch â€" 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
ñañigos 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).
