Speech production and perception are inextricably linked systems. Speakers modify their speech in response to listener characteristics, such as age, hearing ability, and language background. Listener-oriented modifications in speech production, commonly referred to as clear speech, have also been found to affect speech perception by enhancing speech intelligibility for listeners. Similarly, word-specific properties can affect speech production and perception. Less well-understood, however, is the extent to which clear speech and lexical effects interact in speech production and their subsequent effects on speech perception. This topic is investigated in this dissertation with a focus on adult second language (L2) learners to address the extent to which acoustic modifications in speech production support L2 perception. This dissertation presents three experiments examining the interaction of a type of clear speech, foreigner-directed speech (FDS), with three word-specific factors (frequency, lexical age of acquisition, and phonological neighborhood density) on speech production and perception. Results from late Japanese-English bilinguals found that FDS facilitated word recognition, but not lexical access, for adult L2 learners. Independent lexical effects on word recognition and lexical access were also observed in L2 listeners. Interactions between speech condition and lexical effects were seen in word recognition as well, as L2 listeners demonstrated increased word recognition for words from dense phonological neighborhoods produced in FDS. Findings presented in this dissertation indicate that phonological and lexical development in adult L2 learners follows patterns like those observed in first language (L1) learning. One crucial difference between L1 and L2 acquisition is that the advantage of low-frequency/early-acquired words is likely limited to native speakers.
