Course outline

The Topic links will take you to the slides for that lecture. Slides for a lecture will be posted by 8pm the night before the lecture. The PDF links in the Readings column will take you to PDF versions of all required readings (i.e., if no PDF version is available for a paper, the paper is not required reading).

Key for sources of readings:

  • [Holmes]: Speech Synthesis and Recognition, J. Holmes, W. Holmes
  • [R+S]: Theory and Applications of Digital Signal Processing, Rabiner, Schafer
  • [R+J]: Fundamentals of Speech Recognition, Rabiner, Juang
  • [J+M]: Speech and Language Processing, Jurafsky, Martin, 2nd ed.
  • [Jelinek]: Statistical Methods for Speech Recognition, Jelinek
  • [HAH]: Spoken Language Processing, Huang, Acero, Hon
