Interdisciplinary Media project

Interdisciplinary Mediaproject

Module: Interdisciplinary Media Project

LV-Number: 0434 L 923

Language: German/English (according to agreement with students)

Contact Person:Britta Hesse

In this module, the students develop solutions for technical or social science problems connected with digital media using the course content. Both IT skills and analytical social science skills are required to complete this module. The project includes a task from the area of conception, development, or use of a system for the design, recording, transmission, or presentation of media, which is redefined every semester. So, the chair offers usually different project topics for students who should use the above-described skills on the subject. The project work should be solved in a team with interdisciplinary skills; the group organizes itself; the lecturers guarantee regular supervision. Finally, the project results should be presented, and a project report should be delivered.

Winter semester

Speech communication

Speech communication

Integrated Event
(Möller, 4 SWS/6 LP, each WiSe)
LV-Number: 0434 L 900
Language: English

Topics

Speech signals and speech sounds; human speech production; auditory perception; speech signal transmission and coding; speech recognition and speaker recognition; speech synthesis; spoken dialogue systems; multimodal dialogue systems.

Overview

Speech is the most important means of human communication, and more and more it develops into an important modality for human-computer interaction. Already systems work by speech recognition, interpretation of linguistic content, control of dialoge flow, generation  of responses or production of speech signals. Beyond that, the efficient transmission of speech is of utmost importance, both in conventional transmission networks as well as in networks with paket switching (eg. Voice over IP).
In the course of this lecture the basis for unterstanding and designing  communication technology systems based on speech will be provided. Starting with the production and perception of natural human speech will shed light on many important characteristics of speech signals and requirements for their processing. Essential means for representing speech signals in the time and frequency domains will be laid out. On this basis, the functioning of important components of systems of speech technology will be explicated. Apart from efficient coding of speech, speech recognition, speech synthesis, as well as interaction withspeech processing systems (spoken dialogue systems, alternative term: voice user interfaces) will be central. Finally, improvement strategies for the smoother adaption of such systems to human communicative needs via multimodal means of input and output will be presented (multimodal dialogue systems).

Target Group

The lecture has been developed with a focus on students of electrical engineering, computer engineering, as well as computer science. Above these, students from linguistics, communication sciences, engineering acoustics, sociology, human factors, as well as other departments are very welcome. Previous knowledge in speech signal processing or linguistics is not required.

VL-Number: 0434 L 904
Language: English
Contact:

    1. Description

    Communication acoustics consists of all areas of acoustic that deal with the communication between systems, humans or communication between a systems and humans. These are for example: auditory and speech acoustics, electroacoustics, audio technology, the simulation of acoustic environments, as well as all signal processing approaches that are used within these areas. Depending on the focus area of communication acoustics the lectures are part of different faculties, e.g., electrical engineering, physics and computer sience. The MOOC brings together leading scientists in the area of acoustics to create an overview on this versatile topic.

    2. Registration and participation

    Please enrol to the related ISIS course to get further information about the course organization and how to enrol to the related MOOCs on edX.org. Also, the ISIS course will be used as communication platform during the semester, because there are no classic lecture or exercise (meaning no mandatory attendance time).

    Hint: Please write a mail with the subject Key Request to to get the key for self-enrolment.

    Multimodal Interaction

    Multimodal Interaction

    Integrierte Veranstaltung
    (Möller, Kojić, Hillmann; 4 SWS/6 LP; jeweils im SoSe)
    LV-Nummer: 0434 L 917
    Sprache: English

    Contents

    This course lays the foundations for an understanding of multimodal communication between humans and multimodal interaction between humans and machines. We begin by clarifying the basic principles of human-human communication and human-machine interaction. We then describe the processes that occur in humans when they perceive auditory, visual, and tactile signals, and how these perceptions are integrated to form multimodal perception. The signals can be generated and received by machines capable of interacting with humans in limited domains. The design of such machines will be discussed, and the limitations as well as possible solutions to overcome these limitations will be explained.

    The course will be delivered in MOOC format. The entire course will be completed through TUB's ISIS course management system. To facilitate learning, videos and other learning materials will be made available through the course management system.


    Prerequisites

    Basic knowledge of information and communication technologies
