Research summary

Recently, 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 have 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

I teach sub-modules on speech sciences and speech perception, primarily to students taking the MSc in Speech and Language Sciences programme. These modules have an important laboratory component, as each teaching session includes a practical element, which usually involves participating in a speech perception test and analysing the data, or doing some speech analysis.

I currently teach on the following module:
SLAN0005: Management of Communications 2: Speech and Hearing
