General fuzzy controller in the control rules to determine the need, after adjustment, time-consuming and laborious; with a correction factor of fuzzy controller to change the correction factor, the entire control of the table almost affected, would make some point to meet the control requirement has led to some point does not meet the requirements. To solve these problems, proposed a new type of...
Generally, the code excited linear predictive (CELP) coding is known as one of the best algorithms for bit rate between 4 kbps and 16 kbps. Recently, the algebraic CELP (ACELP) algorithm has been widely adopted in standard speech coders such as G.729 and Adaptive multi rate (AMR) and AMR Wide Band (AMR-WB).In order to improve the speech quality based on CELP algorithm, harmonic Pitch pre-emphasis...
