Socio-indexical phonetic features in the heritage language context: Voiceless stop aspiration in the Calabrian community in Toronto

This study examines cross-generational transmission of a sociophonetic variable in a heritage language context. Voiceless stop aspiration is a sociophonetic variable in Calabrian Italian, indexing socio-cultural values about the speaker's social and geographical origin. We investigate the production of voiceless stops by three generations of Calabrian Italians (immigrants and the next two generations) in Toronto, via acoustic and auditory analysis of nearly 5000 tokens from conversational speech in Calabrian Italian.
