Jennifer Bohun Hay is a New Zealand linguist who specialises in sociolinguistics, laboratory phonology, and the history of New Zealand English. As of 2020 she is a full professor at the University of Canterbury.
In 2000, Hay gained a PhD titled Causes and Consequences of Word Structure at Northwestern University in Illinois in the Linguistics department. She moved to the University of Canterbury, and was appointed a full professor in 2010.
Hay's research has revealed that a New Zealand dialect took only a single generation to emerge. She has explored how speech perception and production is influenced by past experiences and current context, including environmental factors: for example, New Zealanders hear vowels differently if they are in a room with toy kangaroos and koalas as opposed to toy kiwi.
Hay is the director of the New Zealand Institute of Language, Brain and Behaviour, a multi-disciplinary research centre based at the University of Canterbury. In 2015 she was awarded a James Cook Research Fellowship to research on how personal experience shapes the New Zealand accent and word use.
In 2017, Hay was featured in the Royal Society Te ApÃÂrangi's 150 women in 150 words project, celebrating the contributions of women to knowledge in New Zealand.
Hay received a Rutherford Discovery Fellowship in 2011, a James Cook Research Fellowship and a University of Canterbury Research Award in 2015, and was made a Fellow of the Royal Society Te ApÃÂrangi in 2015.
