Backchannels in video-mediated ELF conversations: a case study

There are few studies on backchannels in ELF and none concerns computer-mediated conversations. Backchannelling has been associated with good listenership and enhanced cooperativeness, an intrinsic feature of ELF. They would also play a key role in computer-mediated communication, maintaining a sense of affective equilibrium among participants and compensating for medium-related limitations. We analyze backchanneling in an ELF conversation between a Spanish female and a German male student from the Corpus of Video-Mediated English as a Lingua Franca Conversations (ViMELF). Backchanneling seems to be particularly intense in the opening and closing sections of the exchange, where interpersonal work is the most needed. While significant idiolectal differences are observed between the two participants, both show a marked preference for and a tendency to concentrate realizations on a few weak backchanneling forms, conferring the exchange a general impression of monotony and emotional flatness. Some backchanneling features in the exchange may be described as typical of ELF: backchannels tend to occur in moments when speakers sense that understanding may be compromised and are frequently complemented by supportive material reinforcing the speaker’s point. The analysis also reveals some characteristic awkward usage, with tokens which are clearly “overdone,” while others are too weak and disappointing or behave disruptively by occurring in unexpected positions and interrupting the flow of the conversation. Research on ELF video conversations is particularly timely given the recent surge in videoconferencing propitiated by the COVID pandemic, a tendency which is likely to stay in post-pandemic times.
