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 ...
Data compression of natural signals based on Discrete Wavelet transform analysis

Reig Bolaño, Ramon; Martí i Puig, Pere; Solé-Casals, Jordi; Parisi Baradad, Vicenç (2009)
Exploring Non-linear Transformations for an Entropybased Voice Activity Detector

Solé-Casals, Jordi; Martí i Puig, Pere; Reig Bolaño, Ramon (2009)

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 previous ...
Improving Pitch Tracking Performance in Hard Noise Conditions by a Preprocessing Based on Mathematical Morphology

Martí i Puig, Pere; Solé-Casals, Jordi; Reig Bolaño, Ramon (2009)

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 for a ...
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 ...
On cumulant techniques in speech processing

Zaiats, Vladimir; Solé-Casals, Jordi (2009)

This paper analyzes applications of cumulant analysis in speech processing. A special focus is made on different second-order statistics. A dominant role is played by an integral representation for cumulants by means ...
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 ...
