Research

Research Interests:

    My current work primarily focuses on multi-lingual personalised unit selection speech synthesis. My aim is to have a real time TTS system which can speak in a variety of European languages, and also some Asian languages, with multiple voices. The system I created to achieve this is deployed over web services, where any text in any supported language can be synthesised on-the-fly, while taking user preferences into account.

    My research interests are:

    • Methods to automatically learn language pronunciation rules, analyse speech for both acoustic and prosodic information, and build voices entirely automatically off an unannotated collection of speech recordings.
    • Identify synergies between speech synthesis and automatic speech recognition.
    • Automatic learning of phonetic features and applications of them.
    • Unit selection speech synthesis methodologies.
    • Stochastic modelling of speech, for both synthesis and recognition.

    Much of current work is on the design and development of the Muse speech research platform. It's available online at: http://muster.ucd.ie/muse/
