People are now regularly interacting with voice assistants (VAs), which are conversational agents that allow users to use spoken language to interface with a machine to complete tasks. The huge adoption and daily use of VAs by millions of people - and its increasing use for financial, healthcare, and educational applications - raises important questions about the linguistic and social factors that affect spoken language interactions with machines.
We are exploring issues of linguistic and social biases that impact speech communication in human-computer interaction - particularly during cross-language transfer, learning, or adaptation of some kind. In this talk, I will present two case studies illustrating some of our most recent work in this area. The first study looks at a case of cross-language ASR transfer. We find systematic linguistic and phonetic disparities in language transfer by machines trained on a source language to speech recognition of a novel target, low-resource language. The second study looks at a case of social bias in word learning by humans using voice-enabled apps. We find the word learning is inhibited when there are mismatching social cues presented by the voice and the linguistic information.
Together, along with highlights from other ongoing work in my lab, the aim of this talk is to underscore that human-computer linguistic communication is a rich testing ground for investigating issues in speech and language variation. Examining linguistic variation during HCI can enrich and elaborate linguistic theory, as well as present opportunities for linguists to provide insights for improving both the function and fairness of these technologies.

Emerging from the International WAC/WID Mapping Project, this collection of essays is meant to inform decision-making by teachers, program managers, and college/university administrators considering how writing can most appropriately be defined, managed, funded, and taught in the places where they work. Writing Programs Worldwide offers an important global perspective to the growing research literature in the shaping of writing programs. The authors of its program profiles show how innovators at a diverse range of universities on six continents have dealt creatively over many years with day-to-day and long-range issues affecting how students across disciplines and languages grow as communicators and learners. In these profiles, we see teachers and researchers relying on colleagues and on transnational scholarship to build initiatives that are both well suited to their specific environments and can serve as regional and often global models. Their struggles and achievements offer insights to colleagues in similar locales and across borders who seek to establish, enhance, and assess their own work as designers of writing programs. An introduction and three section essays by the editors illuminate themes that inform this collection. Growing networks of initiators and scholars and survey results from the International WAC/WID Mapping Project exemplify the argument of this collection for transnational exchange and collaboration.
