Intern with GeoStat (Geometry and statistics in acquisition data), INRIA Bordeaux-Sud-Ouest (2010, 2011).

Research and contributions

  • Review and implementation of existing text-independent phoneme segmentation algorithms.
  • Conceptualization and development of new text-independent phoneme segmentation methods based on speaker turn detection algorithms and hybridization with non-parametric methods.
  • Implementation of Voice Activity Detection standards and adaptation of TIMIT database for VAD, including methods for evaluating performance of standard and new VAD algorithms.
  • Evaluation of above methods to provide basis for comparison for other methods under development at GeoStat.
  • Previous work in other areas:
    • Research in breaking chaos-based secure optical communications. Examining attractors, study of chaotic dynamics for development of a method for decrypting on-off phase shift keyed chaos-encrypted data.
    • Research in optical fiber bragg gratings for sensing applications. Experimental setup, data collection and analysis.
