This course gives a computer science presentation of automatic speech recognition, the problem of transcribing accurately spoken utterances. The description includes the essential algorithms for creating large-scale speech recognition systems. The algorithms and techniques presented are now used in most research and industrial systems.

Many of the learning and search algorithms and techniques currently used in natural language processing, computational biology, and other areas of application of machine learning were originally designed for tackling speech recognition problems. Speech recognition continues to feed computer science with challenging problems, in particular because of the size of the learning and search problems it generates.

The objective of the course is thus not just to familiarize students with particular algorithms used in speech recognition, but rather use that as a basis to explore general text and speech and machine learning algorithms relevant to a variety of other areas in computer science. The course will make use of several software libraries and will study recent research and publications in this area.

This course is also open to undergraduate students.


Here are some of the topics covered by this course.
