Spatio-temporal Speech Enhancement for Robust Speech Recognition

  title={Spatio-temporal Speech Enhancement for Robust Speech Recognition},
  author={Erik M. Visser and Manabu Otsuka and Te-Won Lee},
A new speech enhancement scheme is presented integrating spatial and temporal signal processing methods for robust speech recognition in noisy environments. The scheme first separates spatially localized point sources from noisy speech signals recorded by two microphones. Blind source separation algorithms assuming no a priori knowledge about the sources… CONTINUE READING
