I think it is impressive how natural-sounding codec2 is even at 1400bps. I am considering a potential application that would be practical only if the bandwidth was a small fraction of even that. It wouldn't be important that the audio sound natural, but it would need to be intelligible. I would like to try reducing the number of bits used for each field in an effort to see how much the bandwidth could be reduced and still provide speech that could be understood. I suppose in the extreme case, the pitch field could be eliminated altogether, resulting in monotone output. Some of the other fields could surely also be reduced somewhat.
If any of you that have worked with codec2 could give me a suggestion about where to focus my efforts, that would be great. Any wild guesses about how far the bandwidth could be reduced and still produce intelligible speech? (I realize that intelligibility is highly subjective). Thanks.
