Chapter 5. What can Cantonese heritage speakers tell us about age of acquisition, linguistic dominance, and sociophonetic variation?

Abstract

For many individuals, the first acquired language is also the linguistically dominant language, but what are the implications for sociophonetic variation if the linguistically dominant language is a second acquired childhood language, as is the case for many heritage speakers? This chapter addresses two correlates of linguistic dominance on the production of L2-influenced vowels in heritage Cantonese sociolinguistic interview data. Results show that Cantonese Production Score (CPS), an externally measured proficiency proxy, is consistently a better predictor than Ethnic Orientation (a self-reported identity metric) in accounting for speakers who are most likely to produce English influenced vowels. While a distinction between child vs. adult language acquisition remains important, these results highlight linguistic dominance as an interacting factor in sociophonetic variation.
