Dagaare [a] is not neutral to ATR harmony

Bodomo (1997) describes Dagaare (Gur; Ghana) as having a single low vowel, [a], which is neutral to ATR harmony. This paper presents acoustic data from a study of Dagaare <a> which is inconsistent with this description. A list of sentences was elicited from five native speakers of Dagaare. Each sentence contained <a> in one of four verbal particles situated in one of four contexts: ATR _ ATR, ATR _ RTR, RTR _ ATR, and RTR _ RTR. Formants of the low vowel were measured and compared across contexts. Results showed a substantial, significant difference in F1 values and a smaller but still significant difference in F2 values in contexts where <a> is followed by an ATR word compared to when it is followed by an RTR word. All speakers and all particles showed the same pattern. We conclude that, contrary to previous claims, the Dagaare low vowel is not neutral to harmony, but rather has acoustically distinct variants in RTR versus ATR contexts. Bodomo, A. (1997).
