Abstract
A synthesizer may synthesize speech by receiving an adaptive codebook excitation signal and an adaptive codebook gain. The adaptive codebook excitation signal may be scaled using the adaptive codebook gain to generate a scaled adaptive codebook excitation signal. A fixed excitation signal and a fixed excitation gain may also be received. The fixed excitation signal may be scaled using the fixed excitation gain to generate a scaled fixed excitation signal. The scaled adaptive codebook excitation signal and the scaled fixed excitation signal may be combined to generate the excitation signal having a first word length. An overall gain signal of the excitation signal may also be received. A scaled excitation signal may then be generated by scaling the excitation signal using the overall gain signal. The scaled excitation signal may have a second word length greater than the first word length.
