Abstract
A speech synthesis system comprises an input terminal for accepting text code, accent code, and phrase code. The speech synthesis system further comprises a converter for converting the text code to speech parameters for speech synthesis; an accent commend generator coupled to an output of the converter for providing a train of accent commands; a phrase command generator coupled to an output of the converter for providing a train of phrase commands; an accent command buffer for storing the accent commands; a phrase command buffer for storing the phrase commands; an accent component calculator operably coupled to the accent command buffer for providing contour of pitch frequency by accent component; a phrase component calculator operably coupled to the phrase command buffer for providing contour of pitch frequency by phrase component; an adder for providing a sum of output signals from the accent component calculator and the phrase component calculator; a device for providing fundamental frequency of voicing which is coupled to an output of the adder; a speech synthesizer coupled to an output of the device for providing the fundamental frequency and output of the converter; and an o…
