Online Speech Recognition Course
Sprague points out that MIT has placed the course materials for its Automatic Speech Recognition course online at its OpenCourseWare site. This course covers quite a bit of Speech Recognition theory. Rita Singh, one of the guest lecturers for this course, was one of the principal speech architects for Sphinx-4. In assignment 8 of this course, Rita uses Sphinx-3 and Sphinx-4 as part of a lab that shows how an HMM decoder works.
