The class is organized by

Rolf Carlson rolf at (Responsible for the course)
Mats Blomberg matsb at

David House davidh at

Dept. Speech, Music and Hearing, KTH, Stockholm, Sweden


The start of the class will be in Göteborg September 15, 2005 followed by one meeting 31/10 – 1/11 and closing seminar in January 2006 both in Stockholm.



The aim of this course is to give an overview of speech technology, some of the underlying theories and models and how these are integrated into applications, such as multimodal dialog systems.


The course is intended for both students with a limited knowledge of the field and for students with a more extensive background in speech technology, who will be expected to take a more active part in the discussion of current research. In this way, the course is also meant to contribute to the common platform for students with different backgrounds in the Nordic graduate school of language technology supported by NorFA.


The course is divided into 5 parts:

Introductory lectures; Reading the listed material; Individual practical exercises; Preparing a term paper; and a Closing seminar including discussions, practical exercises and presentation of the term papers.


Introductory lectures will give an overview of the field with an emphasis on basic concepts and standard methods.


Individual practical exercises will include speech analysis and some other specific tasks related to speech technology. The results should be reported and discussed during the fall period.


During the course a term paper should be prepared by each student. The paper should be presented during the closing seminar in January (Stockholm). The closing seminar includes: Exercises, Presentation of term papers,  Discussion of the reading material and the term papers.



Introductory lecture slides will be linked to each topic.

All teachers


 Individual practical exercises

Phonetic analysis: Each student should carry out an acoustic investigation of their own speech. This exercise will make the student familiar with speech analysis and the basic structure of speech sounds. The results should be summarised and sent to David House before 17/10. The practical exercise will be discussed by all students during the second meeting 31/10 - 1/11. More information can be found on

During the second meeting and the closing seminar additional obligatory exercises on speech recognition and multimodal speech synthesis will be included.

 Term paper

During the course a term paper should be prepared by each student and reviewed by two other students. The paper should be presented during the closing seminar.
