Abstract
The narrowband linear predictive coder (LPC) is becoming widely used in both civilian and military applications. Yet, in spite of the many improvements made over the years, it is still not universally acceptable to general users. Therefore we present improvements to three aspects of the LPC analysis to increase the quality and intelligibility of the narrowband LPC. They are: (1) frequency spreading of voiceless fricative sound spectra, (2) adaptive analysis-window placement at onsets, and (3) suppression of intraframe pitch interference.
