Goal

• To build machines which process speech in the
  same way as humans

How Can Human Science and Engineering Better
Machines Help Each Other?

• Benefits from science to engineering
• Humans do robust processing of speech
• Improved recognition for the Human Machine
  Interface
• Benefits from engineering to science
• Engineers can build machines which test
  hypotheses about the algorithms people use
• Engineering artifacts can pose questions for
  science to answer.

Areas

• Robust speech recognition
• Human listeners can recognise speech in poor
  signal to noise ratios.
• How do they do it?
• Making machine that can aquire language
• What is in Chomskys Language Acquisition
  Toolbox?
• Speaker verification
• Machines can recognise identities of people from
  their voices fairly well.
• How do humans do it and how well?
