Research Themes
Research Summary

Prior to my retirement, most of my research has been concerned with speaker/listener interaction in speech communication, i.e. how speakers adapt the characteristics of their speech production to achieve effective communication in good and poor listening conditions. In a series of four ESRC-funded projects, we investigated the acoustic-phonetic characteristics of speaker-listener interactions in young adults, children with normal and impaired-hearing and older adults. The accent has been on ‘clear speech’ adaptations made in challenging communicative conditions.

I generally have an interest in issues of within- and between-speaker variability in speech perception and production and in the development of speech perception and production in typical and atypical populations.

I have also carried out research on speech perception in second-language learners, on the effectiveness of auditory-visual phonetic training and on audiovisual speech perception.

Teaching Summary

Prior to my retirement, i taught sub-modules on speech sciences and speech perception, primarily to students on the MSc in Speech and Language Sciences programme (SLAN0005: Management of Communications 2: Speech and Hearing). These modules had an important laboratory component, as each teaching session included a practical element, which usually involved participating in a speech perception test and analysing the data, or doing some speech analysis.
