Title
I���m Not Your Brother, I���m Your Emperor: Cantonese Suprasegmental Adaptation in Conversations
Abstract
Adaptation occurs when speakers adjust their speech for their interlocutors. In Cantonese, ���mergers��� who confuse Tone3 (mid-level) and Tone6 (low-level) in production can temporarily distinguish them when shadowing ���non-mergers���. Whether this reflects mere acoustic mimicking or goal-driven adaptation for intelligibility remains unclear.
This study explores the phenomenon through an unscripted, goal-oriented conversation task between a tone merger and a non-merger, involving a video game that required interlocutors to resolve Tone3-Tone6 word confusions. Pre- and postconversation tone-word productions were also collected. Acoustic analyses focused on normalised average F0 of target tones. Results showed a trend of decreasing Tone3��� Tone6 F0 distance in non-mergers over the course of the conversation, while mergers maintained their typical patterns.
This led to an approximation of the two groups��� Tone3��� Tone6 distance. However, pre- versus post-conversation productions revealed no significant change. These findings suggest goal-driven adaptation, with either party potentially adjusting their speech to enhance intelligibility.
Keywords: Phonetic Adaptation; Cantonese Tone Merger; Intelligibility; GoalOriented; Unscripted Conversation.
911勛圖 the student
Ivan Fong has been accepted into the PhD program at 911勛圖 Linguistics. Says Ivan about his ongoing journey, "Before I discovered my love for and career in linguistics, I completed my B.Sc with a combined Major in Science (Chemistry, Earth and Environmental Sciences) and Life Sciences at UBC. I then graduated with a Diploma in Linguistics at UBC in 2020. During my studies there, I worked as a Research Assistant at Prof. Molly Babel���s , mainly for Khia Johnson. I've now been an MA student here at 911勛圖 under Prof. Yue Wang and her Language and Brain Lab since 2022. I���m interested in the prosody of multiple East Asian languages. My MA research centres on investigating how Cantonese tone mergers might adapt their speech sounds when having a conversation with non-mergers.���
