Abstract

Methods of quantifying distance between sound sequences are known as phonological distance measures. Despite the wide application across subfields, phonological distance has been calculated mainly with features related to consonants and vowels. This research report establishes new measurements of phonological distance that incorporate lexical tone through experimental approaches and modeling, using Hong Kong Cantonese as a case study. Results show correspondences between the experimental data and predictions from information-theoretic measures, including entropy measures and functional load, suggesting that lexical components which play a more crucial role in phonological distance judgments are lexically less predictable as well. Implications for phonological distance measures are discussed.
