A practical perceptual frequency autoregressive HMM enhancement system
We have previously developed a speech enhancement scheme which can adapt to unknown additive noise. We model speech and noise using perceptual frequency or ‘warped’ autoregressive HMMs (AR-HMMs) and estimate the clean speech and noise parameters within this framework. In this current work, we investigate the use of our system as a front end to a MFCC recognition system trained on clean speech. ...
متن کاملFrequency Warped All-pole Modeling of Vowel Spectra: Dependence on Voice and Vowel Quality
We address the problem of compactly representing the discrete spectral amplitudes of vowel sounds produced by a sinusoidal model. A study of frequency warped all pole model representation of spectral amplitudes has been presented. It has been generally accepted that incorporating Bark scale frequency warping in the all-pole modeling improves the perceived accuracy of the modeled sound. However ...
متن کاملDiscrete Frequency Warped Wavelets: Theory and Applications - Signal Processing, IEEE Transactions on
In this paper, we extend the definition of dyadic wavelets to include frequency warped wavelets. The new wavelets are generated and the transform computed in discrete-time by alternating the Laguerre transform with perfect reconstruction filterbanks. This scheme provides the unique implementation of orthogonal or biorthogonal warped wavelets by means of rational transfer functions. We show that...
متن کاملThe discrete-time frequency warped wavelet transforms
In this paper we show that the dyadic wavelet transform may be generalized to include non-octave spaced frequency resolution. We introduce orthogonal and complete wavelets whose set of cutoff frequencies may be adapted, in the simplest case, by changing a single parameter. The novel wavelets and the FWWT transform computational structure are obtained via an intermediate Laguerre representation ...
متن کاملAutoregressive causal relation: Digital filtering approach to causality measures in frequency domain
A novel measure of the Autoregressive Causal Relation based on a multivariate autoregressive model is proposed. It reveals the strength of the connections among a simultaneous time series and also the direction of the information flow. It is defined in the frequency domain, similar to the formerly published methods such as: Directed Transfer Function, Direct Directed Transfer Function, Partial ...
