Team meetings are a key part of professional life which are experienced as sociotechnical, interpersonal phenomena. This interview study examines the intersection of modality, disability, and technology in the team meeting setting. Persistent concerns emerged across meeting modalities: participation as a sociotechnical challenge; social/teamwork considerations; stigma, disclosure, and expectations regarding professionalism; a lack of information regarding meetings; productivity problems; and dueling accommodations between disabled individuals. These themes represent challenges about taskwork, teamwork and social perception, and sociotechnical aspects. Findings suggest that flexibility to choose the modality of attendance based on individual context, along with flexibility to choose in-meeting supports, can help with dynamic needs. The accessibility interventions most desired by participants are both readily available and benefit all workers regardless of disability status, but require simultaneous infrastructural, technological, and process interventions to address.

When interacting individuals entrain, they begin to speak more like each other.To support research on entrainment in cooperative multi-party dialogues, we have created a corpus where teams of three or four speakers play two rounds of a cooperative board game.We describe the experimental design and technical infrastructure used to collect our corpus, which consists of audio, video, transcriptions, and questionnaire data for 63 teams (47 hours of audio).We illustrate the use of our corpus as a novel resource for studying team entrainment by 1) developing and evaluating teamlevel acoustic-prosodic entrainment measures that extend existing dyad measures, and 2) investigating relationships between team entrainment and participation dominance.

Lexical entrainment is a measure of how the words that speakers use in a conversation become more similar over time. In this paper, we propose a measure of lexical entrainment for multi-party speaking situations. We apply this score to a corpus of student engineering groups using high-frequency words and project words, and investigate the relationship between lexical entrainment and group success on a class project. Our initial findings show that, using the entrainment score with project-related words, there is a significant difference between the lexical entrainment of high performing groups, which tended to increase with time, and the entrainment for low performing groups, which tended to decrease with time.
