Toda language

Phonology

Vowels

Toda language has sixteen vowels, an unusually large number for a Dravidian language. 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 , which occurs as when short and as or 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 voiceless laterals are true fricatives, not voiceless approximants; the retroflex lateral is highly unusual among the world's languages.

Voiceless fricatives are allophonically voiced intervocalically in Toda. There are also the 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 word-final positions. However, only a restricted set occur word-initially. These are .

Unlike the other dental consonants, is interdental. Similarly, is labiodental whereas the other labials are bilabial.

The palatalized rhotics are only mentioned in Spajić, Ladefoged & Bhaskararao (1996); other descriptions, such as those from Emeneau (1984) and Krishnamurti (2003), only include the three plain trills.

Apical consonants are either alveolar or postalveolar. The actual feature that distinguishes and is uncertain. They have the same primary place of articulation. Spajić and colleagues have found that the rhotic that 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, 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.

The retroflex consonants are subapical. Retroflex is more strongly 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.
