Disentangling word stress and phrasal prosody: A view from Georgian

This paper investigates the interaction of word stress and phrasal prosody in Georgian by studying the distribution of acoustic cues (duration, intensity, F0) in controlled data. The results show that initial syllables in Georgian words are marked by greater duration than all subsequent syllables, regardless of syllable count and phrasal context. After excluding domain-initial strengthening as an alternative explanation, this finding provides evidence in favor of fixed initial stress. Likewise, initial syllables are marked by greatest intensity, but the consistent gradual drop in intensity throughout the word suggests that this effect may not be stress-related. The F0 results align with the existing accounts: individual lexical words form ACCENTUAL PHRASES, marked by a low pitch accent on the initial syllable and a high final boundary tone on the final syllable. Additionally, new evidence for a phrasal accent, aligned with the penult, is presented. F0 targets are shown to be completely absent in the context of post-focal deaccenting, which shows that F0-marking in Georgian is reserved for phrasal prosody and is not intrinsic to stress-marking. These results help account for the facts related to word stress, phrasal intonation, and their interplay in Georgian, the object of debate in the literature.
