Dr Justine Hui


Justine received her conjoint BE(Hons) in Computer Systems Engineering and BA(Hons) (BA in Linguistics and Japanese and BA(Hons) in Asian Studies) at the University of Auckland in 2012. This was followed by several years in industry at IBM seconded to Air NZ as a software developer, while she completed a ME part-time with Dr. Catherine Watson on speech synthesis. She received her PhD at Sophia University, Japan, at the Speech Communication Lab under Prof. Takayuki Arai on the relationship between hearing deficits and speech/melody perception in elderly listeners. 


Research | Current

Her current project examines how language exposure affect our abilities to make use of spatial information in different rooms to understand speech.

She is also currently involved in the MPAi (Māori pronunciation aid) project with A/P Catherine Watson, Dr. Peter Keegan and Dr. Danielle Lottridge, on developing a computer interface based application for users to learn and improve their Māori vowel pronunciation by getting real-time visual feedback. 

She is interested in:

  • phonetics and linguistics 
  • Japanese phonetics
  • te reo Māori phonetics and learning TRM as a second language
  • psychoacoustics
  • speech perception and production of hearing impaired listeners and second language speakers especially in adverse environments (think noisy reverberant cafes)
  • hearing assistive technologies
  • Audio VR (VR acoustics)
  • learning equity of second language speakers
  • second language acquisition
