The goal of the current production study is to investigate both the phonetic (vowel quality and duration) and the phonological (prominence placement) aspects of the acquisition of L2 stress concurrently, focusing on two target languages (French and Spanish; L1 English). Production tasks included carrier phrase reading (108 stimuli for French, 139 for Spanish) and passage reading (French or Spanish version of The North Wind and the Sun). Based on the results from the present sample, there is support for the claim that the phonetics of stress may be acquired with greater difficulty than the phonological aspects. The results speak to the importance of expanding our empirical coverage of language pairings, and of analyzing phonological and phonetic aspects of prosody.
