While previous studies highlight the dynamic nature of identity co-construction, how and especially why speakers construct and shift their own multiple identities still remains understudied. The present study argues that identity is part of speaker communicative resources as evidenced by radio program hosts’ strategic employment and shift among their different identities to facilitate their interactional purposes. Based on data drawn from radio medical consultations, this article attempts to reveal the dynamic adaptability of hosts’ identity construction. It is found that in (...) general, hosts of medical consultation programs construct three identities for themselves, namely an authoritative expert identity, a caring friend identity and a sales representative identity; the three identities constructed are respectively adaptable to power relationships, solidarity and role relationships between hosts and callers in conversation; the three identities shift in conversations to facilitate callers’ purchasing acts.

Since January 2020, Canadian Chief Medical Officers (CMOs) have rapidly evolved into public figures. However, the gendered makeup of this role seems to map onto CMO communication: 10 CMOs are women and 7 use Twitter to communicate, as opposed to 7 men, of whom only 3 have Twitter accounts. Adopting the theoretical lens of language ideology, this paper explores language and gender dimensions of Canadian Chief Medical Officer (CMO) health discourse by analyzing pandemic tweets from CMOs (January 2020-June 2021, 21,389 (...) tweets, 930,0883 words) using corpus-assisted discourse studies. Results suggest that male and female CMOs have not communicated to the same extent, nor have they used the same (range of) languages. Also, there are differences with regard to expressions of authority and compassion. While a paucity of male data poses methodological challenges, it also raises questions about the specific and disproportionate communication work accorded to and undertaken by women. The paper concludes by arguing that female CMOs’ adherence to stereotypically gendered ways of speaking is a strategy for navigating volatile online and offline environments, but that this raises questions about the longer-term impacts of authority in gendered discourse.
