SPEECH SIGNAL ENCODING AND DECODING DEVICE

摘要

PURPOSE:To reduce the size of the device by efficiently transmitting a speech signal by converting the signal into optimum codes. CONSTITUTION:The speech code book of an opposite communication party is loaded in a receiving code book memory 107 from a code book library 106. Further, the code book of a user is loaded in a transmitting code book memory 108 from the code book library 106. Then the speech signal is encoded by referring to the code book loaded in the transmitting code book memory 108 and decoded by referring to the code book loaded in the receiving code book memory 107.
