| Abstract: | By studying the speech coding of multi-band excitation(MBE), self-adaptive spectral enhancement is applied to MBE speech coding, the definition of synthetic speech is upgraded and the quality of synthetic speech is improved. The result of simulation experiment shows that the amplitudes of fundamental frequency and second harmonic of synthetic speech are both increased obviously by using self-adaptive spectral enhancement. So, the definition of synthetic speech is enhanced effectively. |
