Main area of research
Speech recognition

I am a senior research scientist at Nuance, with a focus upon acoustic modelling for the voicemail to text task. Before joining Nuance I was a postdoctoral researcher at Cambridge University and subsequently Sheffield University. My postdoctoral work focused upon domain and speaker-level acoustic model adaptation for both speech recognition and speech synthesis tasks. I graduated in 1994 from the University of Glasgow (Mathematics and Physics). In 1996 I received an MSc in Mathematics and Foundations of Computer Science from Oxford University. In 2003, following seven years of research, development and education in the software industry I pursued an MPhil in Computer Speech, Text and Internet Technology at Cambridge University. I received a PhD in 2008 from Sheffield University. My thesis focused upon unsupervised discriminative acoustic model adaptation for speech recognition.

Application of SVM-based correctness predictions to unsupervised discriminative speaker adaptation

The effectiveness of unsupervised speaker adaptation is typicallylimited by errors in the estimated transcription of theadaptation data. Previous work has mitigated this negativeeffect by using
