    摘要: A synthesis filter is disclosed which models the effect of the fundamental frequency of speech for digital speech coders operating on the analysis-by-synthesis principle. High fundamental frequencies having a period shorter than the corresponding cycle length of the frame employed in the analysis-by-synthesis method are optimally encoded. The filter is constructed of a number of parallel, separately updatable synthesis-memory blocks. When analysis delays shorter than the analysis frame are used, a portion of a signal that was stored in memory several frames earlier is selected and scaled to approximate the missing portion of the analysis frame using the available portion of the analysis frame.

    摘要: This invention is a new kind of parametric speech coding system in which the parametrization according to a speech production model is carried out not only on the speech signal to be coded but also on the decoded, that is, synthesized speech signal. A parametric representation (207) of the synthesized signal is compared with a parametric representation (203) of the original speech signal and the coding functions are controlled according to their difference. At first, parametrization (205) according to the speech production model used in the encoding is carried out on the decoded speech signal. Next, the parameter values formed from the synthesized speech signals are compared (204) with the parameter values (203) calculated, in the encoder, from the speech signal to be coded. A known distance measure can be used in carrying out the comparison. The coding functions are controlled by means of a shaping block (202) in such a way that the difference indicated by the distance measure is made as small as possible.
