Following Ipek & Jun's [1] AM model of intonational phonology of Turkish, it was hypothesized that the high tone realized on the last syllable of a phrase (i.e., Intermediate Phrase (ip)) is realized differently from that of a phrase-medial prosodic word (PW), reflecting the prosodic hierarchy. Acoustic data show that an ip-final High tone shows larger f0 rise than a PW-final High tone, and the ip-final syllable is longer than the PW-final syllable. Furthermore, the degree of coarticulation is weaker across an ip boundary than a PW boundary. These findings support the prosodic structure and tonal categories proposed in Ipek & Jun's [1] model of Turkish intonation.

Results from acoustic analyses shows that speakers do not expand on-focus pitch range but duration and intensity changed as a function of focus. Post-focus pitch is lowered in initial focus, but medial focus did not differ from neutral focus in any of the acoustic parameters. Listeners identified initial focus correctly with the highest rate and this shows the importance of post focus compression (PFC) in correct identification of focus.

Tonal patterns of utterances were examined by varying the length of a word and a phrase, the location of stress, syntactic structures, and sentence types. Preliminary results suggest that Turkish has a H* pitch accent, realized on the stressed syllable of most content words. Each content word forms one Prosodic Word (PW) whose left edge is marked by an L tone. There are two prosodic units higher than PW: an Intermediate Phrase (ip) marked by a final rising (LH) tone and an Intonational Phrase (IP) marked by various types of a final boundary tone. These three prosodic units are also distinguished by the degree of juncture. Interestingly, the ip-final LH boundary tone marks the right edge of a heavy syntactic constituent regardless of the length of the unit. Furthermore, the left edge of a nuclear pitch accent is also marked by a rising tone (LH) which is realized on the last syllable of the immediately preceding PW. The ip-final LH tone and the pre-nuclear LH tone are phonetically different and perceptually distinct.
