【摘要】 本文给出了一种改进的2.4kb/s多带激励线性预测(IMBELP)语音编码算法。与传统的MBELP算法相比,本算法在基音提取和清/浊音判决上采取了一些改进措施,使得合成语音质量有一定的提高。本文详细介绍了改进后的MBELP算法,并将其在基音提取和清/浊音判决的结果与传统的MBELP进行比较。
【Abstract】 This paper gives an improved MBELP speech coding algorithm at 2.4kbls.Compared with conventiona MBELP algorithm,this algorithm has some improvements on pitch estimation and unvoicelvoice decision.The synthetica speech of vocoder based on this algorithm is better than that based on conventional one.After a brief introduction,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.
【Key words】 MBE coder; MBELP coder; pitch estimation; U/V decision;
