Toda language

Toda is a Dravidian language well known for its many fricatives and trills. It is spoken by the Toda people, a population of about one thousand who live in the Nilgiri Hills of southern India.

Vowels

For a Dravidian language, Toda's sixteen vowels is an unusually large number. There are eight vowel qualities, each of which may occur long or short. There is little difference in quality between the long and short vowels, except for /e/, which occurs as when short and as when long.

Consonants

Toda has an unusually large number of fricatives and trills. Its seven places of articulation are the most for any Dravidian language. (The apical coronals are marginally postalveolar, and are sometimes judged to be alveolar instead.) The voiceless laterals are true fricatives, not voiceless approximants; the retroflex is highly unusual among the world's languages.

Despite the ad hoc use of the retroflex flap symbol , all rhotics are trills, although (as in Spanish and Italian) they have single-contact allophones. Indeed, is the most strongly trilled of Toda's rhotics.

Toda voiceless fricatives are allophonically voiced intervocalically. (There are also invariably voiced fricatives, , though the latter is marginal.) The nasals and are allophonically devoiced or partially devoiced in final position or next to voiceless consonants.

All of these consonants may occur in word-medial and -final position. However, only a retricted set occur initially. These are in boldface above.
The actual feature that distinguishes is obscure. They have the same primary place of articulation. Spajić et al. have found that the rhotic which may occur word initially (erroneously called "dental" in previous literature, perhaps because Dravidian coronals tend to be dental by default) has a secondary articulation, which they have tentatively identified as advanced tongue root until further measurements can be made. This analysis is assumed in the transcription .

Another difference between them is that is the least strongly trilled of Toda's rhotics, most often occurring with a single contact. However, unlike a flap, multiple contacts are normal, if less common, and is easily distinguishable from the other trills when they are all produced with the same number of contacts.

As mentioned above, the retroflex trill is more consistently trilled than the other rhotics. However, it is not purely retroflex. Although the tongue starts out in a sub-apical retroflex position, trilling involves the tip of the tongue, and this causes it to move forward toward the alveolar ridge. This means that the retroflex trill gives a preceding vowel retroflex coloration the way other retroflex consonants do, but that the vibration itself is not much different from the other trills.
