This study investigates the phonetic production of Spanish-English insertional code-switches, constituents of an embedded language inserted within a discourse of a matrix language. While previous research on the phonetics of code-switching has focused exclusively on the segmental properties, the current study provides a detailed examination of the suprasegmental features of code-switched tokens, including pitch height and duration. Code-switched productions are compared with non-code-switched tokens, and results indicate that insertional code-switched tokens are produced with a degree of hyper-articulation, evidenced by an increase in pitch height and duration. The results are discussed within Hyper- and Hypo-articulation Theory, drawing on the notion of a decreased local probability incurred by insertional code-switches.
