A speech synthesis system includes a phonological converter, a word parser, a syllable parser, temporal and parametric interpreters, a file and a synthesizer. The word parser and syllable parser receive an input text which includes words in a defined word class. The word parser parses each word to determine whether it belongs to the defined class of words. The parser includes a knowledge base containing the individual morphemes utilized in the defined word class, each morpheme being a root or an affix, the binding properties of each root and each affix, the binding properties for each affix also defining the binding properties of the combination of the affix and another affix or another root, and a set of rules defining the manner in which the roots and affixes may be combined to fore words. The syllable parser determines the phonological features of the constituents of each syllable of the input text. The metrical parser determines the stress pattern of the syllables of each word. The temporal and parametric interpreters interpret the phonological features together with the stress pattern to produce a series of sets of parametric values for driving the synthesizer. The synthesizer produces a speech waveform. If desired, the parameter values may be stored in the file for later use. |
