This paper deals with the designing of the forward adaptive μ-law companding quantizer whose levels are coded with the Golomb-Rice code. The designing is performed for measurement signals with the Gaussian distribution and applied for the speech signal. The model satisfies the G. 712 standard and achieves the decreasing of the bit-rate for 1.34 bps (bits per sample) compared to the G. 711 standard. [Projekat Ministarstva nauke Republike Srbije, br.
