Research Projects
- Speech Perception and Language Acquisition in Children with Hearing Impairments
(2009-2012)
How do children with hearing aids and cochlear implants learn their native language?
Can they use the same learning mechanisms and acoustic cues as their normal-hearing peers?
In this study, we examine what children with hearing impairments know about the sound structure of their native language. We are also interested in finding out how they acquire this knowledge and whether it is correlated with their vocabulary and grammar skills.
- Auditory Specialization for Speech Perception
(2008-2011)
Individuals are born with an ability to discern speech sounds (phonemes) in all of the world's languages, but they develop through childhood so that they become specialized to perceive native-language phonemes. The aim of this study is to test our hypothesis that this specialization for native-language phonemes begins to occur in central auditory processing, at a functional level prior to linguistic categorization. The work uses behavioural measures and MEG to examine and perception of English phonemes by adult native speakers of Sinhala and Japanese
- Clarifying the speech perception deficits of dyslexic children
(2005-2008)
This project will investigate how children with specific reading difficulties (dyslexia) and those who are reading normally perceive the sounds of speech. To decode speech, listeners need to be able to ignore ‘irrelevant’ variation in the speech signal that is linked to differences in speaker, speaking style, accent, etc. It is claimed that children with SRD are more sensitive to these variations than other children. We will check this claim using tests in which we can manipulate specific acoustic patterns within the word. We will then test children’s perception of many different consonants to try and better understand what makes some more difficult to identify than others. Finally, we will test children’s ability to adapt to different speakers and speaking styles.
