ABSTRACT:
A speech synthesis application specific integrated circuit (ASIC) based on an Line Spectrum Pair (LSP) scheme. In the ASIC, the LSP parameter is encoded and two's complement fixed-point serial pipeline arithmetic operations with rounding are performed by an LSP speech synthesis digital filter. The operating rate demanded for the ASIC is low, and the elements of the ASIC are mostly in serial shift structure. So, the area of the LSP speech synthesis ASIC is much less than the conventional chip.
