INTERNSHIP DESCRIPTION

We provide software components for the telephony industry aiming for speech enhancement in communications. One of these components addresses specifically the improvement of speech intelligibility and is thus highly related to perceptual aspects. The main objective of this internship is to specifically design subjective listening tests seeking perceptual optimization of this component.

Main steps :

  • Study and understanding of NXP’s speech intelligibility improvement solutions
  • Design of subjective listening tests
  • Conduction of the tests
  • Analysis of test results
  • Integration within NXP’s solution

Required skills :

  • (Audio) Signal Processing
  • MATLAB
  • Good written and spoken English

This internship is an opportunity to learn both speech processing and subjective testing aspects in an industrial environment. It can potentially lead to direct employment or a Ph.D. thesis in signal/speech processing.
