This study investigates the production of / θ / and / ð / by three groups of English speakers in the community of Norwich, Ontario, Canada. English monolinguals, Heritage Dutch speakers, and late-learning Dutch L1 English speakers / θ / and / ð / production was measured in both naturalistic and reading tasks. Heritage Dutch speakers produce [θ] and [ð] at similar levels to Monolingual English speakers, the two groups use different allophone inventories especially in the initial position of / ð / and the medial-position of / θ /. This study suggests that despite having native English accents, Dutch Heritage speakers may manipulate the inherently variable English / θ / and / ð / production to communicate their Dutch cultural identity.
