Towards speech technology for South African languages: automatic speech recognition in Xhosa

Autor: F A de Wet, E. C. Botha

Publikováno v: South African Journal of African Languages. 19:216-226

This article reports on the first application of ‘state-of-the-art’ automatic speech recognition (ASR) technology to Xhosa, an indigenous South African language. The project, aimed at developing the technology required to implement a spoken-langu

Aircraft down-range profiles formed from simulated and compact-range radar backscatter

Autor: K. M. Geggus, Johann W. Odendaal, E. C. Botha

Publikováno v: Microwave and Optical Technology Letters. 17:207-213

Compact-range radar backscatter measurements are taken of aircraft scale models. In addition, computer software is used to predict the RCS of the aircraft. Synthetic down-range profiles formed from the two sources of backscatter data are compared and

2D microwave imaging using TLS-ESPRIT with matrix enhancement

Autor: Johann W. Odendaal, E. C. Botha, A. van der Merwe

Publikováno v: Microwave and Optical Technology Letters. 8:218-222

In this article TLS-ESPRIT [1] will be used to generate two-dimensional high-resolution microwave images. To enable the utilization of the 1D algorithm, a two-dimensional data matrix is decoupled into two one-dimensional sequences by forming an enhan

Leap-frog is a robust algorithm for training neural networks

Autor: J E, Holm, E C, Botha

Publikováno v: Network (Bristol, England). 10(1)

Optimization of perceptron neural network classifiers requires an optimization algorithm that is robust. In general, the best network is selected after a number of optimization trials. An effective optimization algorithm generates good weight-vector
