PhD Studentship in Speaker Diarization at EURECOM

Department: Multimedia Communications
Start date: 01/10/12
Duration:   Duration of the thesis


EURECOM’s Multimedia Communications Department invites applications for a PhD studentship in speaker diarization within its Speech and Audio Processing Research Group.  Speaker diarization is commonly referred to as the task of detecting ‘who spoke when’ in a multiple-speaker audio signal.  In its most general form it is performed without any prior
knowledge regarding the number of speakers or speaker identities. applications include speech recognition, speaker recognition (biometrics), multimedia indexing, content structuring and general multimedia document processing.

As with any modelling or statistical pattern recognition task, performance is affected by unwanted nuisance variation and by the amount of data available for any given class.  In the case of speaker diarization performance  can be affected by background noise, varying
linguistic content and differences in speaker floor times.   Our recent work has developed new normalization approaches to marginalise linguistic variation in order to increase speaker discrimination and improve speaker diarization performance.

This fully-funded PhD position aims to extend this work to further improve the robustness of speaker diarization in the case of linguistic  variation and varying speaker floor times.  The work will develop a novel phone adaptive training algorithm and investigate other, new normalisation and marginalization approaches to improve speaker modelling.  The position is an opportunity to make a contribution in an increasingly important field of speech and audio processing.  You will join a small, but dynamic research group which participates in a growing number of European, national and industrially-funded research projects and will have the opportunity for international travel and participation in competitive evaluations.


The successful candidate will have a Master’s degree in engineering, mathematics, computing or a related, relevant discipline.  You will be highly motivated to undertake challenging research, have strong expertise in mathematics and programming and have excellent communication skills.  Knowledge of C/C++ and Matlab is strongly desirable.  Good English language speaking and writing skills are essential.  Knowledge of French is a bonus.  Application  Screening of applications will begin immediately, and the search will continue until the position is filled. Applicants should send, to the address below (i) a one page statement of research interests and motivation, (ii) your CV and (iii) contact details for three referees.

Applications should be submitted by e-mail to

EURECOM is a graduate school and a Research Centre in Communication Systems, located in Sophia Antipolis technology park, in close proximity with a large number of research units of leading multinational corporations in the telecommunications, semiconductor and biotechnology sectors, as well as other outstanding research and teaching institutions. EURECOM was founded in 1991 by TELECOM ParisTech (Ecole Nationale Supérieure des Télécommunications) and EPFL (Swiss federal institute of Lausanne) in a consortium form, combining academic and industrial partners.

EURECOM deploys its expertise around three major fields: Networking and security, Multimedia Communications and Mobile Communications and has a strong international scope and strategy. EURECOM is particularly active in research in its areas of excellence while also training a large number of doctoral candidates. Its contractual research is recognized across Europe and contributes largely to its budget.
