International Symposium on Signal Processing and Its Applications (ISSPA)
作者: Saikat Chatterjee T.V. Sreenivas Department of Electrical Communication Engineering Indian Institute of Science Bangalore India
We explore the performance of two dimensional (2-D) prediction based LSF quantization method for both wide-band and telephone-band (narrow-band) speech. The 2-D prediction based method exploits both the inter-frame an... 详细信息
