Interaction of quantity, foot structure, and stress in the 2nd/3rd syllable sonorants of Soikkola Ingrian trisyllables

The talk describes interaction between phonological quantity (originally, binary) and the compensatory effects of foot structure in sonorants at the 2nd and the 3rd syllable boundary (C3) in the trisyllabic foot of vanishing Soikkola Ingrian (Finnic). Such interaction had been previously observed as a phonetic effect in the 1st syllable segments and as a phonological impact on the 2nd syllable vowels [1]. C3 sonorants are also affected, both phonologically and phonetically, and their binary length contrast is almost lost. Depending on the foot structure, original C3 sonorant geminates are either retained, or nearly or completely shortened to singletons. This result is placed within other results on the trisyllabic foot, which appears to be a coherent metrical unit different from both the disyllabic foot and the bifoot trisyllabic word in Soikkola Ingrian.
