and ψ=0 at V ≥VD. By using the Hankel transform for coordinate β, combined with Eqs. (9) and (10), At(λ) can be further determined as follows: (15) where δ(λ) is the delta function. F1(λ) and F2(λ......

with the delta and delta-delta function increases the robustness and reliability of the TMFCC coefficients. Step out of the feature extraction is the change of activity detection. Voice activity detection... in the feature vectors is reduced by the cepstral mean variance normalization (CMVN). The addition of the delta and delta-delta of a coefficient with TMFCC coefficients improves [21] the recognition......
