Situated learning for collaboration across language barriers
Project Leader: Greg Wadley
Staff: Trevor Cohn
Collaborators: Steven Bird (Charles Darwin University)

Keywords: computational linguistics; interaction design; machine learning; mobile phones
Disciplines: Computing and Information Systems
People working in development are often deployed to remote locations where they work alongside locals who speak an unwritten minority language. Outsiders and locals share know-how and pick up phrases in each other’s languages. They are performing a type of situated learning of language and culture. This situation is found across the world, in developing countries, border zones, and in Indigenous communities.
This project will investigate new methods for cross-lingual collaboration, drawing on the state of the art in speech processing, deep learning, and interaction design. The research will be evaluated in terms of the effectiveness of the interaction, the acquisition of language, and the quantity of language data collected. The ultimate goal is to contribute to the grand challenge of sustaining the world's linguistic diversity.
We’re looking for outstanding and highly motivated PhD candidates with personal experience of linguistic diversity. Successful applicants will divide their time between Charles Darwin University and the University of Melbourne, undertaking a PhD at CDU and jointly supervised by researchers at Melbourne. Candidates will be supported to conduct fieldwork in a remote Indigenous community. Indigenous candidates are strongly encouraged to apply. Candidates are expected to have a degree in computer science or related discipline, advanced programming skills, and a background in one of more of: machine learning, speech processing, interaction design.
The deadline for scholarship applications is 31 October 2018.
The project will build on previous work in the following areas:
- mobile platforms for collecting spoken language data [6, 7]
- respeaking as a technique for improving the value of recordings made ‘in the wild’ and an alternative to traditional transcription practices [14, 16]
- machine learning of structure in phrase-aligned bilingual speech recordings [2, 3, 4, 8, 9, 10, 11]
- participatory design of mobile technologies for working with minority languages 
- designing with Indigenous communities [12, 13, 15]
- managing multilingual databases of text, speech and images .
Some recent indicative PhD theses include:
- Computer Supported Collaborative Language Documentation (Florian Hanke, 2017)
- Automatic Understanding of Unwritten Languages (Oliver Adams, 2018)
- Collecter, Transcrire, Analyser : quand la Machine Assiste le Linguiste dans son Travail de Terrain (Elodie Gauthier, 2018)
- Enriching Endangered Language Resources using Translations (Antonios Anastasopoulos, in prep)
- Digital Tool Deployment for Language Documentation (Mat Bettinson, in prep)
- Bayesian and Neural Modeling for Multi Level and Crosslingual Alignment (Pierre Godard, in prep).
