A parallel processor for real-time speech signal processing

Abstract

This paper describes the structure of a parallel processing system, primarily suitable for real-time Linear Prediction (LP) analysis and synthesis of speech signals. This system employs specially developed parallel forms of the well known algorithms (Levinson's Recursion, SIFT as well as LP synthesis filter) for this purpose. The feasibility of implementing the proposed structure using microprogrammable microprocessors, is then discussed. The proposed scheme can be readily adapted for on-line identification of autoregressive processes.
