ABSTRACT:
The present invention provides syllable boundaries from a string of phonological linguistic unit indicia and word boundary data. The syllable boundary recognizer places a syllable boundary either at the next following word boundary or prior to the second vowel phonological linguistic unit indicia following the prior syllable boundary based upon the sequence of consonant phonological linguistic unit indicia prior to that second vowel. A permitted syllable initial consonant cluster includes an optional fricative consonant, an optional stop consonant and an optional sonorant consonant. The syllable boundary recognizer searches backward from the second vowel phonological linguistic unit indicia until the permitted sequence is violated, whereupon a syllable boundary is inserted. In the preferred embodiment, a refinement permits certain strong vowel phonological linguistic unit indicia to "capture" the following phonological linguistic unit indicia and shift the syllable boundary. This technique is most useful in low data rate speech systems which provide intonation based upon syllables.
