ABSTRACT:
A speech and moving picture coding and decoding system wherein pictures which are close to real pictures and look more natural than ever are displayed by a simple method without the necessity of complicated processing for picture analysis or picture synthesis and pictures which look like pictures in a real speaking condition can be decoded and reproduced with high picture quality even where the transmission capacity is restricted low is disclosed. On the transmission side, input speech is coded while it is simultaneously analyzed by a speech analysis section, and an input picture corresponding to a result of the speech recognition is coded by a picture coding section and transmitted. On the reception side, the coded picture is decoded and stored into a picture memory. Then, the coded speech received is decoded by a speech decoding section, and one of stored pictures corresponding to the received result of speech recognition is read out from the picture memory.
