Resumen de Wordform-specific frequency effects cause acoustic variation in zero-inflected homophones
Eva Maria Luef, Jong-Seung Sun
The frequency with which a word appears in the lexicon has implications for its pronunciation. Numerous studies have shown that high-frequency lemma are characterized by more phonetic reduction than lower-frequency lemma. These findings have proven to be particularly useful in the study of homophones where frequency-related reduction processes can give insights into lexical access theories. The majority of research on homophones and frequency effects has focused on heterographic and semantically unrelated homophones (e.g., English time – thyme ) or investigated zero-derived homophones (e.g., English the cut , noun – to cut , verb). Here, zero inflection in German pluralization (e.g., ein Würfel ‘one die’– zwei Würfel ‘two dice’) was investigated to determine if and how frequency effects impact on the acoustic realization of the homophonous singular-plural word pairs. The findings indicate that the number-specified wordforms show acoustic variation related to wordform frequency and the relative frequency of the singular to plural inflected forms. Results differ for durations of wordforms, stem vowels, and final phonemes. Our findings have implications for lexical access theories and can inform about ‘frequency inheritance’ across the singular and plural homophones of the zero-inflected plurals.
