Catherine Breslin

I am currently a research associate in the Dialogue Systems group run by Prof Steve Young in the Machine Intelligence Laboratory at Cambridge University Engineering Department.

Prior to joining the group, I studied Engineering and Computer Science at Oxford University, graduating in 2003, before completing an MPhil in Computer Speech, Text and Internet Technology at Cambridge University in 2004. I undertook my PhD under the supervision of Dr Mark Gales in 2004-08, on generating and combining complementary systems for automatic speech recognition, and subsequently worked for Toshiba Research until 2012.

I instituted the Friday speech group seminars within the speech group.

Current project and research interests

  • Online automatic speech recognition (ASR) and voice activity detection (VAD) for dialogue systems
  • Combining VAD and ASR for improved performance
  • End-of-turn detection for improved turn-taking in dialogue
  • Incremental recognition and adaptation for more flexible dialogue management
