Abstract
Input text is converted to a sequence of representations of syllables or other phonetic units and stored portions of data are retrieved to generate waveforms corresponding to the syllables. In order to determine durations for the syllables, a constant duration is defined corresponding to a regular beat period and adjusted in accordance with the nature of the syllable and/or its context within the sequence.
