Topic-based variation as both cognitive and agentive

Topic-based style-shifting refers to the variation pattern that, when people talk about a topic, they shift to a linguistic style which is associated with the topic. Most of the research on topic-based variation in read speech have not taken stance-taking into consideration. This study argues that stance-taking needs to be included in the analysis of topic-based variation, for reading something aloud is a practice where individuals engage with the message communicated in a text. This study looks at the socially salient variable /ʂ/ in Taiwan Mandarin, and how deaf speakers exploit this variable to perform their stances towards a passage concerned with the political relationship between hearing people and deaf signers. The findings show that participants who demonstrate a stance of deaf solidarity diverge from standard speech styles in their repertoires when reading the deaf passage.
