part-time employment may be possible
The majority of systems and services that are provided by computer science, electrical engineering and information technology finally are oriented on the needs of their human users. To successfully build such systems and services it is essential to investigate and understand users and their behavior when interacting with technology. On the one hand, this understanding allows to derive design principles for human-machine-interfaces and to define requirements concerning the system and its underlying technologies. On the other hand, new available technologies offer new possibilities regarding the design of such interfaces and the development of new kinds of interaction.
The Quality and Usability Lab is part of TU Berlin’s Faculty IV and deals with the design and evaluation of human-machine interaction. Here, the main subjects of our research are human perception, aspects of technical systems that are related to the interaction as well as interaction design.
The position is to do research in the field of speech signals analysis and the determination of speech quality in different (mobile and fixed) networks. Therefore, speech signals of the speaker are to be analyzed in relation to extractable features (for example permanent pathological changes, temporary emotional states) or the perceived quality of speech. Based on these analyses, signal-based and parametric models for the estimation of speech quality can be extended and integrated. One focus here may be the detection of speech production disorders (e.g. post-stroke apahsia). The modified models are to be validated based on subjective hearing and conversation tests. For this purpose, methods of crowd working should also be applied, i. e. real users should carry out the data collection and/or evaluation via an online platform. Scientifically interesting is the comparison of such data to those that can be obtained under laboratory conditions. The topic can provide a basis for preparing a doctoral dissertation.
The concrete tasks include, among other things:
Building of recording and retention platforms connected to real (mobile and fixed) transmission networks
Implementation and further development of a mobile platform for user data collection
Analysis of speech signals
Estimation of quality aspects using different algorithms
Implementation of data collections and assessments in the crowd and in the laboratory
Project communication and reporting
Publication and presentation of project and research results in scientific journals, at conferences, and in workshops
Successfully completed university degree (Master, Diplom or equivalent) in electrical engineering, computer engineering/science, informatics, media informatics, information systems (or an equivalent technical background)
Profound knowledge in digital signal processing, beneficial: speech signal processing respectively audio signal processing
Good programming skills (eg. MatLab or Python) and safe handling of development tools (eg. Android Studio, HTML5/CSS3, JS, jQuery, JSON, RESTful API, ideally backend development skills)
Interest in running user studies with test subjects to determinate speech quality
Language skills: English and German fluent in writing and speaking
Knowledge about empirical studies and statistical data analysis is appreciated
Joy of working in an interdisciplinary and international environment
