متن کاملImproving word accuracy with Gabor feature extraction
A novel type of feature extraction for automatic speech recognition is investigated. Two-dimensional Gabor functions, with varying extents and tuned to different rates and directions of spectro-temporal modulation, are applied as filters to a spectro-temporal representation provided by mel spectra. The use of these functions is motivated by findings in neurophysiology and psychoacoustics. Data-...
متن کاملLung Sound Noise Reduction Using Gabor Time-Frequency Masking
The Gabor expansion is a mathematical tool, which provides a joint time-frequency representation of a given signal by decomposing it into time-frequency elementary signals called Gabor atoms. It has been used in a variety of signal processing applications, including biomedical signal processing. In this paper we present a time-frequency masking technique based on Gabor expansion for both heart ...
متن کاملVoiced/unvoiced speech discrimination in noise using Gabor atomic decomposition
A new algorithm is developed for voiced-unvoiced speech discrimination in noise. Short segments of speech are modeled as a sum of basis functions from a Gabor dictionary. In each iteration, a Gabor atom is fitted (using the matching pursuit algorithm) to the residual obtained by subtracting the best-fit Gabor atom from the previous residual. Multiple discriminant analysis is used to reduce the ...
