F0 Peak Alignment, F0 Peak Location, and Focus Perception in Taif Arabic

The encoding of focus and its role in Taif Arabic has not been understood fully. A recent production study found significant acoustic differences between syntactically identical utterances with focus and without focus. The current study aims to investigate further F0 peak alignment, F0 peak location and (b) focus perception in Taif Arabic. The acoustic analyses of F0 peak alignment and F0 peak location show that only the F0 peak alignment of the post-focus words was realized earlier than that of their counterparts under neutral-focus condition, and the location of the F0 peak of the stressed syllable of the post-focus words was lower than that of their counterparts in neutral-focus utterances. In focus perception, correct focus identification was 85% for initial focus and 71% for penultimate focus. These findings have implications for both focus typology and language variations.
