  • Applications of Cumulants in Speech Processing
    Zaiats, Vladimir; Solé-Casals, Jordi; Martí i Puig, Pere; Reig Bolaño, Ramon (Springer, 2010)
    This paper analyzes applications of cumulant analysis in speech processing. The main focus is made on an integral representation for cUl1luJants using integrals involving cyclic products of kernels. These integrals serve ...
  • Coding of Biosignals Using the Discrete Wavelet Decomposition
    Reig Bolaño, Ramon; Martí i Puig, Pere; Solé-Casals, Jordi; Zaiats, Vladimir; Parisi Baradad, Vicenç (Springer, 2010)
    Abstract. Wavelet derived codification techniques are widespread used in image codifiers. The wavelet based compression methods are adequate for representing transients. In this paper we explore the use of the discrete ...
  • Mathematical Morphology Preprocessing to Mitigate AWGN Effects: Improving Pitch Tracking Performance in Hard Noise Conditions
    Martí i Puig, Pere; Solé-Casals, Jordi; Reig Bolaño, Ramon; Zaiats, Vladimir (Springer, 2010)
    Abstract. In this paper we show how a nonlinear preprocessing of speech signal -with high noise- based on morphological filters improves the performance of robust algorithms for pitch tracking (RAPT). This result happens ...
  • Score Function for Voice Activity Detection
    Solé-Casals, Jordi; Martí i Puig, Pere; Reig Bolaño, Ramon; Zaiats, Vladimir (Springer, 2010)
    In this paper we explore the use of non-linear transformations in order to improve the performance of an entropy based voice activity detector (VAD). The idea of using a non-linear transformation comes from some ...
