Communication Breakdowns Between Families and Alexa.

We investigate how families repair communication breakdowns with digital home assistants. We recruited 10 diverse families to use an Amazon Echo Dot in their homes for four weeks. All families had at least one child between four and 17 years old. Each family participated in pre- and post- deployment interviews. Their interactions with the Echo Dot (Alexa) were audio recorded throughout the study. We analyzed 59 communication breakdown interactions between family members and Alexa, framing our analysis with concepts from HCI and speech-language pathology. Our findings indicate that family members collaborate using discourse scaffolding (supportive communication guidance) and a variety of speech and language modifications in their attempts to repair communication breakdowns with Alexa. Alexa's responses also influence the repair strategies that families use. Designers can relieve the communication repair burden that primarily rests with families by increasing digital home assistants' abilities to collaborate together with users to repair communication breakdowns.
