- The MELP vocoder has a good performance at 2.4 kb/s and is selected as the Federal Standard Vocoder of the United States. However, due to the simple U/V decision of MELP, desired synthesis performance is not achieved in transition frames. This paper presents an improved MELP algorithm in which transition frame is detected and processed on the basis of peakiness detection. Comparison results are given both in time domain waveform and PESQ tests. Better synthesized speech quality is provided by using the improved MELP algorithm
