N2 - Code Excited Linear Prediction (CELP) is a closed-loop analysis-by- synthesis speech coding algorithm that has been standardized in Federal Standard-1016. Variants of the CELP algorithm form the core of many speech coding standards that exist today. In this paper, we discuss the development of an interactive speech coding tool in National Instruments LabVIEW software for the Federal Standard-1016 CELP algorithm. A brief description of the speech coding algorithm and the features of the LabVIEW speech coding tool are presented. Illustrations demonstrating the use of the interactive software tool in analyzing the speech coding algorithm are provided. This tool can be used to teach the various modules of the CELP based speech coders to undergraduate and graduate students.
