Abstract

The formant information for identifying place of articulation in voiced plosives is conventionally represented using two acoustic attributes, namely F2onsetand F2mid(e.g. [7, 9, 16]). This study compares the accuracy of such a technique with a new technique in which F2onsetand F2midare collapsed into a single attribute, termed F2R. Thismethod involves subtracting F2onsetfrom F2mid, multiplying this frequency difference by a constant(c),and subtracting this product from F2onset, yielding F2R. Results from a discriminant analysis(leave-one-out cross-validation)show that F2Rcan distinguish the place of articulation of /b d g/ at approximately the same rate as the conventional method using F2onsetand F2mid.Given that thisresult accordswellwith the 1950s locus theory [3], itsuggests that the locus theory held animportantinsight that was neglected in phoneticsciencefollowing Öhman’s [15] findings forVCV sequences
