Abstract
Speech is analyzed for phonological linguistic units (phonemes or allophones), along with their duration pattern and pitch pattern contour as a group or string of a syllable. The patterns are encoded as the best-match pattern in a set of prestored standard patterns. This data is transmitted to a synthesizer to help in the intonation reconstruction of speech.
