Speech analysis, speech enhancement, speech synthesis
In recent telecommunications system uses a limited audio signal bandwidth of 300 to 3400 Hz. In recent times it has been proposed that the mobile phone networks with increased audio signal bandwidth of 50Hz-7 KHz will increase the sound quality of the spe
