Energy and entropy based switching algorithm for speech endpoint detection in varying SNR conditions
In this work, we present an algorithm that switches between the energy and the entropy based voice activity detectors (VADs) to provide an improved performance under varying signal to noise ratio (SNR) conditions. The motivation for switching has come from the observed complementary behavior in the noise estimation performances of energy and entropy based voice activity detectors when evaluated...
متن کاملPreprocessing time series with ICA and savitzky-golay filtering
In this paper we summarize various possible techniques such as Crossover Prediction Model or the classical Principal Component Analysis (PCA) tool to include exogenous data. Furthermore we propose a new method for volatile time series forecasting using Independent Component Analysis (ICA) algorithms and Savitzky-Golay filtering as preprocessing tools. The preprocessed data will be introduce in ...
متن کاملImproved Threshold Scheme for Energy Detection In Cognitive Radio Under Low SNR
Spectrum scarcity causes hurdle in implementation of emerging wirelessapplications which requiremore frequency spectrum. Cognitive radio (CR) has provided a promising solution to the current spectral requirement problem by efficient spectrum sharing. Spectrum sensing (SS) is one ofthe most important element in CR networks.Many SS algorithms have been proposed in thepast. Among these algorithms,...
متن کاملAn Improved Entropy-based Endpoint Detection Algorithm
It is found that the detection using basic spectral entropy becomes difficult and inaccurate when speech signals are contaminated by high noise. This paper presents an improved entropy-based algorithm. The way to compute spectral probability density function of entropy is altered by the introduction of a positive constant. The modification improves the discriminability between speech and noise ...
متن کاملSpeech Enhancement based on Savitzky–Golay Smoothing Filter
Speech denoising is the process of removing unwanted sounds from the speech signal. In the presence of noise, it is difficult for the listener to understand the message of the speech signal. Also, the presence of noise in speech signal will degrade the performance of various signal processing tasks like speech recognition, speaker recognition, speaker verification etc. Many methods have been wi...
