This dissertation presents an investigation of non-uniform time sampling methods for spectral/temporal feature extraction in speech. Frame-based features were computed based on an encoding of the global spectral shape using a Discrete Cosine Transform. In most current " standard " methods, trajectory (dynamic) features are determined from frame-based(More)
The eld of computer simulation has been advanced by the availability of distributed computer platforms and software architectures which take advantage of those platforms. A great deal of eeort has gone into the development of distributed simulation environments and object-oriented simulation in military applications. The maturation process of these(More)
