pb425 Modern Speech Technology (Course overview)

First Insight into Signal- or System Theory

1 written exam (30 - 60 minutes) or

1 oral exam (20 - 30 minutes) or

1 formal presentation ( 20 - 30 minutes)

The course provides the engineering tools for modern speech signal processing. It complements the physiological aspects of speech generation and the psychoacoustic aspects of speech perception provided by the companion course "Einführung in die Sprachverarbeitung" (pb185) by teaching the technical representation of speech in algorithms, hardware and software. Special attention is devoted to the task of speech signal enhancement in several facets, such as noise filtering, reverberation reduction and echo cancellation. The required tools of modern speech processing are presented here in an elementary and intuitive manner. Mathematical requirements are moderate to low. The exercises are implemented in software or on the blackboard by the students themselves or in teams and, if necessary, with component-wise support by the lecturers. The students thus gain a preliminary insight into the scientific working method for student qualification projects, such as the bachelor thesis, as well as into the engineering working method in the industrial environment of speech processing.
