Some Student Projects Supervised

Final year projects

Semester projects

  • Reconnaissance du locuteur dans le domaine forensique , Azzabi Zouraq Salim , semester project, 2003, Swiss Federal Institute of Technology, Lausanne (EPFL)
  • Development of a prototype forensic automatic speaker recognition system in Matlab , Andrea Rizzi , semester project, 2005, Communication Systems, Swiss Federal Institute of Technology, Lausanne (EPFL) In this project, Andrea has developed a forensic automatic speaker recognition system prototype completely in Matlab. This demo uses some freely available libraries and implements the approach presented in this paper Here's his presentation. (Demo link to appear soon)
  • Automatic Speaker Recognition using Universal Background Model (UBM) and MAP adaptation , Zhong Zhong Ni , semester project, 2005, Communication Systems, Swiss Federal Institute of Technology, Lausanne (EPFL) Here's his presentation.

Tutorials and demos

  • Automatic Speaker Recognition: A Simple Demonstration using Matlab, for the Biometrics course, Communication Systems, EPFL, 2004. You can find the sample audio recordings and the matlab code here.
  • Some examples of generating and sampling language from stochastic context free grammars (SCFG)

    This is some code I'd written in 2001 as part of a project in natural language processing that concerns stochastic context free grammars. I'm providing the code in hope that it might be a starting point for someone playing with grammars and NLP. This code is provided as is, i.e, use it as you see fit, the author absolves himself of any responsibility and will not be able to answer specific questions about the code.
    It contains:

    • scfg2txt : A sampling program that generates the language from a given stochastic context free grammar
    • bigramcounter : Perl code and sample grammars for the program that counts the total number as well as the relative frequencies of the different bigrams in a text
    • scfg2cnf : Perl code and sample grammars for the program that converts the SCFG into Chomsky Normal Form
    • grammarcreation : Contains the perl code and sample grammars for the program that gets the transition probabilities from a grammar in CNF
    You can download a zip file for the Perl and C code here and the documentation here
