Chapter 1 pointed out that voice waveforms could be converted to binary data by sampling at 8000 times per second and quantizing to 8 bits per sample, yielding 64 kbps. It then said that modern speech coders can yield telephone-quality speech at 6-16 kbps. If your objective were simply to reproduce the words in speech recognizably without concern for speaker recognition, intonation, etc., make an estimate of how many kbps would be required. Explain your reasoning. (Note: there is clearly no "correct answer" here; the question is too vague for that. The point of the question is to get used to questioning objectives and approaches.)
