4.1.1.2Labial and lingual

Differences in degree of overlap and assimilation have been reported to occur between sequences composed of labial and lingual stop consonants as well.

In agreement with the coarticulatory resistance hierarchy, greater overlap has been found to occur in sequences with a labial C1 than in those with a velar C1 whenever C2 is a dentoalveolar stop. This difference in gestural overlap holds for /pt/ > /kt/ in Greek (word initially and word medially; Yip, 2013) and in Korean and Russian (word medially and across a word bounday in the former language and in C#C sequences in the latter; Kochetov et al., 2007), and for /phth/ > /gd/ in Georgian (word initially and word medially according to Chitoran et al., 2002 and word initially according to Goldstein et al., 2009). The reverse relationship, i.e., more overlap for /kt/ than for /pt/, has been reported to take place in Portuguese (word medially, Cunha, 2014), though this apparent exception could be attributed to the fact that /kt/ was embedded in longer words than /pt/: (/pt) captar “to catch”, captador “catcher”; (/kt/) compactado “compacted”, compactador “compactor”.

Regarding stop cluster pairs showing a reverse place combination, a comparison between labial + velar and velar + labial sequences show the expected differences in degree of overlap, namely, /bg/ > /gb/ in Georgian (see above) and in Moroccan Arabic (word medially; Zeroual et al., 2014). More overlap for /bg/ than for /gb/ could be associated with the fact that C1 is labial in /bg/ and velar in /gb/ and also that C2 is velar in the former sequence and bilabial in the latter. Differences in degree of overlap between labial+velar and velar+labial sequences have implications for assimilatory patterns, as revealed by Korean where /pk/ but not /kp/ undergoes regressive assimilation. As to the pairs of sequences with a dentoalveolar and a labial, more overlap has been reported to take place in labial+front lingual clusters than in front lingual+labial ones in Georgian (/phth/ > /thb/, word initially and word medially; Chitoran et al., 2002) and Moroccan Arabic (/bd/ > /db/, word medially; Zeroual et al., 2014). This difference in degree of gestural overlap is not consistent with the trend for /t/ to assimilate to following /p/ and for /p/ to not assimilate to following /t/ in languages like Korean and Catalan (see also descriptive data for Cairene Arabic in section 4.1.1.1), and could be associated with the fast motion of the tongue front articulator for the production of apical and apicolaminal consonants.

The predicted patterns of gestural overlap are also consistent with production data for cluster pairs where C1 remains constant. Thus, in sequences with a labial C1 the consonant is more overlapped by a following velar stop than by a following dentoalveolar stop, as revealed by data taken from Moroccan Arabic (/bg/ > /bd/; Zeroual et al., 2014) and marginally from English (/p#k/ > /p#t/; Gao et al., 2011). In agreement with this pattern of gestural overlap, regressive assimilation in clusters with C1=/p/ applies only when the labial stop precedes /k/ in Korean (Kochetov & Pouplier, 2008, Son et al.
