Code Excited Linear Prediction (CELP) algorithms are proposed for compression of speech in 8 kHz band at switched or variable bit rate and algorithmic delay not exceeding 2 msec. Two structures of Low-Delay CELP coders are analyzed: Low-delay sparse excitation and mixed excitation CELP. Sparse excitation is based on MP-MLQ and multilayer models. https://ffxexyie9ra70.timeblog.net/70687804/current-data-on-rickettsia-felis-occurrence-in-vectors-human-and-animal-hosts-in-europe-a-scoping-review
