Abstract :
A speech recognition system is described for recognizing isolated words from reference templates created by concatenating demisyllables from a corpus of about 1000 demisyllables. The composition (in terms of demisyllables) of each reference word is specified in a lexicon with one or more entries for each word of the vocabulary. Experiments were carried out, using a 100-word vocabulary, to investigate the usefulness of such a representation and the effect on performance of some simple modifications in demisyllable specification and durations of reference patterns. Recognition accuracy of 97.6% was obtained using 132 reference templates for the 100-word vocabulary.
