<p>In a speech encoding apparatus, a pitch of an input speech signal is analyzed, and a basic waveform of one pitch of the input speech signal is derived. A number of a pair or pairs of pulse elements of a desired framework is decided, and the desired framework is generated in response to the basic waveform. The generated desired framework is encoded. An inter-element waveform code book contains predetermined inter-element waveform samples which are identified by different identification numbers. Inter-element waveforms which extend between the elements of the framework are encoded by use of the inter-element waveform code book. <IMAGE></p> |
