This paper proposes a method of designing the adaptive uniform quantizer for frame by frame LPC coefficients quantization. The method firstly determines the support region thresholds of two uniform quantizers designated to quantize the minimal and the maximal value of LPC coefficients of each frame. Based on this, the uniform quantizer thresholds estimation for LPC coefficients quantization are provided. The results obtained by testing the proposed method in processing the speech signal from the TIMIT data base are presented and disscused in the paper.

W artykule zaproponowano metodę zuniformowane go adaptacyjne kwantowania współczynnika LPC (linear prediction coders). Początkowo obliczana jest minimalna i maksymalna wartość LPC dla każdej ramki. Następnie zuniformowany współczynnik jest określany. Zaprezentowano test metody na przykładzie przetwarzania sygnału mowy z bazy TIMIT.
