Chief Technology Officer - Living First Language Platform

The Living First Language platform preserves and revitalises Indigenous First Languages and turns them into dynamic, community-led and interactive digital literacy apps. In 2019, the platform won in its category of ‘Innovation in Connecting People’ at the South by Southwest (SXSW) Innovation Awards in Austin, Texas. We are incredibly honoured to be a recipient of this prestigious award, which is a win for First Languages in Australia and has the potential to impact individuals and communities across the globe.In Australia, First Languages are disappearing at a faster rate than anywhere in the world despite a universal acknowledgment that language plays a vital role in the health, wellbeing, education and future of Indigenous peoples. The Living First Language project harnesses technology in order to stem the tide of loss of First Languages and empower children to become learners in their Mother Tongues. ALNF’s technological solution offers a faster and more scalable means to efficiently and effectively capture and share languages.Within Australia alone, 81,100 people identify as the speaker of an Indigenous language and 276,300 people who identify language as part of heritage. Globally, there are over 350 million Indigenous people across 90 countries worldwide. Yet, we can all benefit from this project, which will raise awareness of Indigenous languages and make them more accessible.ALNF hopes that the impact of this initiative goes beyond preservation of Language, and that the platform serves to strengthen communities, bridge cultural divides, foster resilience, encourage literacy and puts First Language back into community members’ hands.
