TL;DR: The use of demisyllables for continuous speech recognition in a specific application: the recognition of Spanish numbers, with excellent results in both applications.
Abstract: This communication reports the use of demisyllables for continuous speech recognition in a specific application: the recognition of Spanish numbers. After a brief outline of the recognition system, a description of demisyllable syntactic constraints and one-speaker reference generation is provided. Finally, the recognition performance is assessed by means of two experiments: the recognition of integer numbers from zero to one thousand and telephone numbers uttered in a Spanish way (strings of integers from zero to ninety nine), in both applications the results that the system yielded were excellent.

TL;DR: The use of an orthogonal expansion for feature selection and data compression in isolated word recognition is presented and the recognition results as well as the meaning of the orthogsonal expansion are discussed.
Abstract: The use of an orthogonal expansion for feature selection and data compression in isolated word recognition is presented. Assuming that the spectral evolution, given by a LPC analysis, is a noisy measure in the sense that it is a linear combination of a set of real features, the objective of the orthogonal expansion is to find these real features. The new feature vectors are used to perform the recognition process. The recognition results as well as the meaning of the orthogonal expansion are discussed. >
