According to our previous study, more than half of minimum data in the band-pass filtered waveform can be substituted by average of the contiguous maximum data, with achieving lower than 4% of phase error. Not only approximate 67% reduction of processing time but also less than half of file size, e.g., approximate 65% saving of 1-h speech data, has been attained, releasing three types of the. ext file format for the extremal data. Further, a design of shared memory has played on important role in performance of response on a single processor system of PC-AT compatible computer, offering that length and number of blocks, and sampling frequency were 16,384-byte, 2 and 22,050hz, respectively. We have improved the acquisition system for the speech bandwidth (80-5,120Hz), in which conventional pulse-code-modulated data series can be simply converted to the extremal data in the tem-pro-spectral domain, generating files every 1.5-s, for manipulation of fine acoustic structure, synthesis, succeeding processes for recognition and/or categorization, and so forth.","subitem_description_type":"Abstract"}]},"item_3_full_name_183":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"38936","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YOSHIDA,
