This paper considers whether the phonology of the lexical pitch accent of Kyungsang Korean is being maintained by younger innovative speakers. We examine the pitch-accent patterns of nouns with various suffixes by comparing the speech of innovative Kyungsang speakers to that of older conservative speakers. It will be shown that while innovative speakers maintain the underlying distinction in the lexical pitch accent found with conservative speakers, the acoustic difference across the contrastive accent classes is substantially weaker in the speech of innovative speakers, for both noun stems and suffixes. Observation of individual differences in the phonetic realisation of the pitch accent and comparison with tonal patterns of Seoul Korean provide an insight into this sound change, offering evidence for how and why the acoustic distinction has weakened. This study thus documents a process of diachronic change in the prosody of Kyungsang Korean.
