On speaker commitment and speaker involvement. Evidence from evidentials in Spanish talk-in-interaction

Abstract

In this paper I raise the question of how the concepts of speaker commitment and speaker involvement can be applied to evidential expressions. I therefore explore the distinction between commitment and non-commitment as a binary opposition (cf. Katriel and Dascal, 1989; Kissine, 2008) and show that a choice for a binary opposition leads to a clear differentiation of epistemic and evidential markers. Speaker involvement is different from speaker commitment, in that it is gradable. This notion will be relevant at both a propositional and an interactional level of analysis. At the propositional level, I claim that speaker involvement refers to the speaker’s processing of the evidential qualification when presenting a state of affairs. At the interactional level, speaker involvement will be shown to play a role in the online planning of the flow of discourse. In my corpus analysis of the Spanish evidential adverbials al parecer ‘apparently’ and por lo visto ‘seemingly’, I will argue that the coparticipant’s reply to evidentially qualified propositions is an important methodological tool to examine speaker involvement. Moreover, the monitoring of the evidential dimension in interaction will shed new light on non-commitment (cf. Déchaine et al., 2017).
