It is well-known that interlocutors who entrain to one another have more
successful conversations than those who do not. Previous research has shown
that interlocutors entrain on linguistic features in both written and spoken
monolingual domains. More recent work on code-switched communication has also
shown preliminary evidence of entrainment on certain aspects of code-switching
(CSW). However, such studies of entrainment in code-switched domains have been
extremely few and restricted to human-machine textual interactions. Our work
studies code-switched spontaneous speech between humans by answering the
following questions: 1) Do patterns of written and spoken entrainment in
monolingual settings generalize to code-switched settings? 2) Do patterns of
entrainment on code-switching in generated text generalize to spontaneous
code-switched speech? We find evidence of affirmative answers to both of these
questions, with important implications for the potentially "universal" nature
of entrainment as a communication phenomenon, and potential applications in
inclusive and interactive speech technology
