SPEECH SYNTHESIS SYSTEM AND PROSODIC CONTROL METHOD IN THE SPEECH SYNTHESIS SYSTEM

A prosodic parameter for an input text is computed by storing a sentence of vocalized speech in a speech corpus memory, searching for a stored text having a similar prosody to an input text as a key to the speech corpus and modifying the prosodic parameter based upon the search results. Because a plurality of prosodic parameters are handled as a linking data, a synthesized sound similar to natural speech having a natural intonation and prosody is produced.
