Title:
VOICE PROCESSING FILTER AND VOICE SYNTHESIZING DEVICE
Document Type and Number:
Japanese Patent JP2993396
Kind Code:
B2
Abstract:
PURPOSE: To obtain good formant emphasized effect within a range of allowable spectrum gradient by calculating correction LSP(line spectrum pair) based on LSP of a voice signal and outputting it.
CONSTITUTION: A first LSP correction means 6 obtains an interior division value of LSP 5 and the prescribed LSP, and outputs obtained LSP to a first LPC(line predictive coding) conversion means 8 as a first correction LSP 7. A second LSP correction means 10 obtains an interior division value of LSP 5 and the prescribed LSP same as the first LSP correction means 6, and outputs obtained LSP to a second LPC conversion means 12 as a second correction LSP 11. Since this device is constituted so that formant emphasizing processing is performed using correction LSP obtained by performing correction for LSP of a voice signal, good formant emphasized effect in which guarantee for stability at the time of correction is easily performed, the degree of freedom for correction is high, and which is good within a range of allowable spectrum gradient can be obtained.
