Abstract： |
A method for picking up fundamental tone cycle based on dynamic plan includes using inverse filtering to carry out spectrum flattening operation, limiting inverse filtering zero point position in concentric circle of a unit circle in unit circle, using section function to calculate path price and inputting voices-voiceless sound information for obtaining better picking-up performance under low time delay. |
