Conventional treatments of vowel harmony processes routinely make two important assumptions: first, only vowels are implicated in the harmonic process and second, the phonologically relevant harmony features have a transparent (intrinsic) phonetic interpretation (IPI). Consonants are typically treated only insofar as they interfere with such harmony (van der Hulst & van der Weijer 1995 provide a concise overview of harmony processes and their interpretation). Phonetic data on ‘advanced tongue root’ [ATR] harmony in the Tugen dialect of Kalenjin appears to challenge both these assumptions.
