  • This thesis presents a new way of modeling variation in production and perception within and across lexical categories. By adding lexical indexes to both the input and relevant faithfulness constraints in a Noisy Harmonic Grammar model, I will show that production frequencies be used to predict well-formedness judgments of variable forms. First I show that by using this model, an artificial learner in Praat (Version 5.1.43) can learn the appropriate production frequencies of variants showing -s deletion and aspiration in Spanish. In Experiment 1 I show that Puerto Rican Spanish speakers choose sentences with aspirated adjectives as more well-formed than sentences with aspirated nouns. In Experiment 2, participants' perception of ambiguous phonemes along a continuum from [h] to [s] is significantly influenced by the lexical category of the root to which the ambiguous fricative is attached. These results support the predictions made about perception judgments based on variable production frequencies.
