LP-TRAPs in all senses

This report describes additional experiments with LP-TRAPs -- speech features derived from autoregressive model applied to approximate temporal evolution of speech spectra in critical band-sized frequency sub-bands. The importance of free parameters, such as order model, length of the approximated temporal pattern, compression factor, or number of resulting cepstral coefficients, is investigated and evaluated using TANDEM-ASR approach.
