Subject: Open PhD positions at Deutsche Telekom Labs, TU Berlin From: Alexander Raake <Alexander.Raake@xxxxxxxx> Date: Mon, 22 Feb 2010 21:58:56 +0100 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>Dear colleagues, The research group "Assessment of IP-based Applications" of Deutsche Telekom Laboratories, which is part of Berlin Institute of Technology (TU Berlin) currently has two open PhD positions in the field of VoIP-based Services and Quality Assessment (2 years initial funding, can be prolonged): ---------------------------- * PhD Position 1 "Quality of VoIP" Description Our goal is to carry out research in the area of services based on Voice over IP and the perceived quality it is related with. Here, aspects at signal-, network- and perception-level will be considered. The research will be conducted with the aim of developing quality prediction models and measurement approaches for VoIP service monitoring. Selected goals * Investigate the role of temporal aspects in the context of IP-based transmission, considering the relevant time-scales at packet-, speech, and perception-level. * Investigate the impact of the transmitted signal form on the perceived speech quality. * Investigate the quality related with new telephone services with extended bandwidth (wideband, 50-7000 Hz, superwideband, 50-14000 Hz). * Research on models for speech quality prediction and tools for monitoring IP-based speech services. Requirements The successful candidate holds a diploma or master's degree in Electrical Engineering, Computer Science, Communication Sciences, or a comparable field. For this position, genuine interest in and knowledge of telecommunications, the willingness to work in an international and interdisciplinary team, and the capability of independent work are a must. Solid knowledge of acoustics or speech technology, and interest in auditory perception, as well as knowledge of the English language are required, prior knowledge of auditory or speech perception and knowledge of MATLAB and C(++) are a definite plus. ---------------------------- * PhD Position 2 "Evaluation of interactive audiovisual speech communication" Description Our goal is to investigate the impact of degradations of interactive IP-based applications such as VoIP that can only be assessed in a conversational situation, or that affect a conversation in a specific way. One prominent example is that of transmission delay, where the turn-taking of participants may be degraded, although the transmitted speech and video signals can be of high quality. The addressed services are two-party VoIP, multiparty audio-conferencing, video-telephony, and videoconferencing. Goals * Adapt and combine existing systems for VoIP & videotelephony simulation. * Identify transmission-related technological degradations of relevance for interactive multimedia services. * Identify conversation-related perceptual cues that may be affected by these degradations. * Identify, adapt, and develop methods for the evaluation of interactive audiovisual speech communication services with human subjects, reflecting identified cues. * Determine quantitative relations between human performance and quality perception during conversations when using interactive multimedia applications, and develop corresponding prediction models. Requirements The successful candidate holds a diploma or master's degree in Electrical Engineering, Computer Science, Communication Sciences, Computer Linguistics, or a comparable field. For this position, genuine interest in and knowledge of telecommunications, the willingness to work in an international and interdisciplinary team, and the capability of independent work are a must. Solid knowledge of acoustics or of video technologies and programming in C or C++, and interest in auditory and visual perception, as well as knowledge of the English language are required. Prior knowledge of auditory or visual perception and experience with MATLAB are a definite plus. ---------------------------- Environment Deutsche Telekom Laboratories (T-Labs) is a joint scientific research institute of Deutsche Telekom AG and Berlin Institute of Technology (TU Berlin). We carry out pioneering research into innovative information and telecommunication technologies, in particular addressing human perception and interaction, networking and security issues. The Laboratories are located on the campus of Berlin University of Technology, with the goal of promoting the interaction between science and business through physical proximity. The Assessment of IP-based Applications Lab of Deutsche Telekom Laboratories (Alexander Raake) is a newly founded research group, which carries out research on IP-based multimedia applications and user perception. The work will be conducted in exchange with other researchers working, for example, on parametric IPTV- and video-telephony quality models, multimedia transmission, audio-rendering and speech quality assessment, together with the Quality and Usability Lab of Deutsche Telekom Laboratories (www.qu.tlabs.tu-berlin.de). ---------------------------- How to apply Applications including a CV, a motivation letter, copies of the most important certificates, and indication of 2 references should be sent, as soon as possible (and before March 12th), to these two addresses: Alexander Raake (alexander.raake (a) telekom.de), AND laboratories.researchscientist(a)telekom.de TU Berlin seeks to increase the percentage of female employees and particularly encourages female candidates to apply. In case of equal qualifications, female candidates will be preferred. Handicapped candidates will be preferred in case of equal qualifications. ---------------------------- Thanks for your consideration and kind regards Alexander _________________________________ Alexander Raake Assessment of IP-based Applications Deutsche Telekom Laboratories TU Berlin Ernst-Reuter-Platz 7 10587 Berlin Germany Fon: +49-30-8353-58462 Fax: +49-30-8353-58409 www.deutsche-telekom-laboratories.de _________________________________
