Sumario:The main objective of this dissertation is to examine the consequences of bilingualism on speech production. Previous research has shown that bilingual speakers experience a cost compared to monolinguals in a variety of linguistic experiments. We investigated the origins of the bilingual cost by exploring influences of particular variables such as phonological similarity. Moreover, we investigated the scope of the bilingual cost by assessing speech performance, focusing on articulatory durations and noun-phrase production. We provide evidence that increased phonological similarity among words within one language slows speech, whereas increased phonological similarity across translations helps bilinguals to overcome the bilingual cost. In addition, our results show that the bilingual cost generalizes to articulatory durations and noun-phrase production. The current dissertation provides a more specific understanding of speech processing at phonological and articulatory stages in mono- and bilinguals, and extends our knowledge on the bilingual cost in speech production.
