This paper presents a linguistic analysis of Spanish-English bilingual speech for scholars and practitioners of bilingualism. More specifically, the study surveys several outcomes of language contact, among these, inter-lingual transference, codeswitching, and convergence, as evidenced in the speech practices of heritage Spanish speakers in the United States. The emergent assessment is linguistically informed, thereby illuminating our understanding of bilingual speech forms, and encourages perspectives and pedagogies that validate bilingual speech practices.
