A First Visit to the Robot Language Café
Skantze, Gabriel; Engwall, Olov; Lopes, José. - : KTH, Tal-kommunikation, 2017. : Stockholm, 2017
Abstract: We present an exploratory study on using a social robot in a conversational setting to practice a second language. The prac- tice is carried out within a so called language cafe ́, with two second language learners and one native moderator; a human or a robot; engaging in social small talk. We compare the in- teractions with the human and robot moderators and perform a qualitative analysis of the potentials of a social robot as a con- versational partner for language learning. Interactions with the robot are carried out in a wizard-of-Oz setting, in which the native moderator who leads the corresponding human moder- ator session controls the robot. The observations of the video recorded sessions and the subject questionnaires suggest that the appropriate learner level for the practice is elementary (A1 to A21), for whom the structured, slightly repetitive interaction pattern was perceived as beneficial. We identify both some key features that are appreciated by the learners and technological parts that need further development. ; QC 20180111
