Limitation: the lack of end-to-end userfacing applications that interact directly with users in multilingual communities.

1. Although computational implementations of grammatical models of C-S exist (Bhat et al., 2016), they do not necessarily generate natural C-S utterances that a bilingual speaker would produce

2. Most crucially, current computational approaches to C-S language technologies do not usually take into account the linguistic and social factors that influence why and when speakers/users choose to code-switch.
