Abstract:

This technical report covers a variety of topics and research areas. An update of the Canonical Coordinate CC Transformation process for digital speech compression based on non-Euclidean error minimization criteria is given. A method of transforming empirical filter sets to unitary error metrics is introduced and a sample error metric is developed. Research into frequency shift invariant transformation is presented and its utility for developing CC error metrics is discussed. A study into the relationship between CC analysis and Linear Predictive Coding is presented. An improved AP120-B implementation of the CC algorithm is given along with a fully parallel CC implementation on a systolic array processor. The latest developments in processor hardware, operating systems, and program development software at RADCEEV are documented. Custom additions to the Interactive Laboratory System ILS analysis and display package are covered along with its relationship to the Speech Data Base Library used at RADCEEV. Data Base inputoutput programs, analysis tools, searchsort programs are all presented. The status of a communicability testbed system at the Speech Processing Facility is presented.
