Abstract (en)

[origin: WO8404194A1] A speech pattern is compressed to a degree not previously attainable by analyzing the pattern to generate (210, 215, 275, 280) a sequence of signals representative of its acoustic feature at a first rate. Responsive to the acoustic feature feature signals, a sequence of speech event representative signals is generated (225, 275, 280). A sequence of coded signals corresponding to the speech pattern is formed (235, 275, 280) at rate less than said first rate responsive to the speech event representative signals.
