Model-based analysis of speech and audio signals for real-time processing based on time-varying lattice filters


In this paper, a time-varying analysis procedure based on lattice filters is proposed for real-time processing. The analysis procedure estimates the reflection coefficients from the signal frames successively in a way that the current frame is analyzed with respect to previous frames. For that purpose, a linear coefficient trajectory covering the current… (More)
