| Abstract: | This paper presents an improved MBELP speech encoding algorithm at 2.4kb/s.Compared with conventional MBELP algorithm, this algorithm improves pitch estimation and unvoice/voice decision. The synthetic speech of vocoder based on this algorithm is better than that based on conventional one. The improved MBELP algorithm is discussed in detail and the results of pitch estimation and U/V decision based on the improved MBELP are compared with those based on conventional MBELP. |
