Performance evaluation of speech quantization:

Given an original speech segment "speech.dat" sampled at 8,000 Hz with each sample encoded in 16 bits, use Programs 2.3 to 2.5 and modify Program 2.2 to quantize the speech segment using 3 to 15 bits, respectively. The SNR in dB must be measured for each quantization. The MATLAB function: "sound(x/max (abs(x)),fs)" can be used to evaluate sound quality, where "x" is the speech segment while "fs" is the sampling rate of 8,000 Hz. In this project, create a plot of the measured SNR (dB) versus the number of bits and discuss the effect on the sound quality. For comparisons, plot the original speech and the quantized one using 3 bits, 8 bits, and 15 bits.
