Publikation Nr. 3955 - Details Even, C. (2022). Siri-ous Trouble: How Older Adults Handle Trouble Sources in First Exchanges with the Conversational Interface Siri, Hengstberger Symposium, Heidelberg. URL: https://doi.org/10.6084/m9.figshare.20101754.v1 Abstract Siri-ous Trouble: How Older Adults Handle Trouble Sources in First Speech Exchanges with the Conversational Interface Siri This PhD-project investigates how adults adapt to a ‘conversational interface’ (CI) (McTear et al., 2016) when they use it for the first time. Various forms of adaptation in so-called human-machine-interaction are known to emerge in the context of interactional trouble, i.e., problems of understanding or repair (e.g., Oviatt et al., 1998; Pelikan & Broth, 2016). These adaptations also constitute a known phenomenon in the adoption process of novice users of CIs (e.g., Luger & Sellen, 2016; Pins et al., 2020). However, insights into user adaptation are mostly drawn from retrospective self-reports in interview studies. In contrast, this work aims to reconstruct the detailed conversational courses of ‘repair’ (Schegloff et al., 1977) and possible ensuing adaptation, applying ‘Conversation Analysis’ (Sidnell & Stivers, 2013) as method. The data collection consists of video recordings of 21 adults using the CI ‘Siri’ for appointment entries. Analysis of a collection of six older adults (65-74 y.o.) was guided by the following research questions: 1. What kind of trouble sources emerge? 2. How do older adults initiate or operate repair – with what kind of outcome? Analysis reveals that older adults often show less variety in their conversational practices, e.g., by re-using their first choice of speech input in following appointment entries – even in cases of wrong entries. Moreover, they tend not to initiate or operate repair. Thus, successful task fulfilment occurs to a lesser extent than in younger adults. Attribute:
