LP-TRAP: linear predictive temporal patterns

  title={LP-TRAP: linear predictive temporal patterns},
  author={Marios Athineos and Hynek Hermansky and Daniel P. W. Ellis},
Autoregressive modeling is applied for approximating the temporal evolution of spectral density in critical-band-sized subbands of a segment of speech signal. The generalized autocorrelation linear predictive technique allows for a compromise between fitting the peaks and the troughs of the Hilbert envelope of the signal in the sub-band. The cosine transform coefficients of the approximated sub-band envelopes, computed recursively from the all-pole polynomials, are used as inputs to a TRAP… CONTINUE READING
