Research and Development for Digital Voice Processing.
Abstract
This technical report covers a variety of topics and development areas. Original research on the decomposition of a Canonical Coordinate Transformation process based on non-Euclidean error minimization criteria is covered. The implementation of an algorithm resulting form this work and its application to sample error metrics is described. The definition of an algorithm resulting from this work and its application to sample error metrics is described. The definition of a spectral moment error metric and the development of statistical and empirical non-Euclidean error criteria are covered. Test results from several experimental vocoders using this algorithm and specific error metrics are presented. The results of original research on the characterization of the acoustic background noise for several Air Force platforms is covered in depth. A study of Linear Predictive Coding improvements and their implementations at RADC (EEV) is given along with details on the installation of several array processor vocoder algorithms. The status and latest developments of processor hardware, operating systems and program development software are documented.
