I carry out research on the voice, and on its role in speech communication, on the prosodic and segmental structure of Irish, and on speech technology for Irish. This research is carried out with the research group of the Phonetics & Speech Lab. The voice carries different strands of information: personal (on the identity and characteristics of the speaker), linguistic (shaping the prosodic structure of the message) and paralinguistic (through tone-of-voice conveying our feelings and attitude to the speaker and to the message). I am interested particularly on the interaction of the latter two, which together make up the 'prosody of the voice', and work towards the elaboration a more holistic model of speech prosody, using specialised voice analysis techniques developed here at TCD. I also research the prosody and segmentals of Irish and of Irish English. Developing speech technology for Irish dialects is a further research interest that builds on the theoretical and empirical strands of my research. Text-to-speech systems, developed for Irish dialects, are made available at, and along with this, a growing body of resources, aimed at language users/learners, and at disability access. This work on Irish aims further to explore how speech technology resources can play a role in the maintenance and preservation of endangered languages.
