1. A speech synthesis system comprising:
- a character analyzing means for analyzing a series of input characters to generate a series of syllabic symbols and a series of rhythmic symbols according to the series of input characters;
a plurality of parameter file means for storing speech parameters determined by taking into consideration an influence of immediately preceding vowels of the syllabic symbols;
a speech parameter generating means for generating a series of speech parameters by combining speech parameters obtained from said parameter file means in accordance with a determined vowel immediately preceding a syllabic symbol of said series of syllabic symbols;
rhythmic parameter generating means for generating a series of rhythmic parameters according to the series of rhythmic symbols supplied from said character analyzing means; and
a speech synthesizing means for synthesizing said series of speech parameters and said series of rhythmic parameters.

Abstract
In order to generate a series of speech parameters from a series of phonemic symbols extracted from a series of input characters, parameters for given syllables or phonemes are read from corresponding parameter files according to the types of immediately preceding vowels or consonants of the given syllables or phonemes in the series of phonemic symbols. The syllable or phoneme parameters ar combined to produce a series of speech parameters.
