I tried to make use of some public audio research and it was pretty bad. There was an audio comprehensibility competition a few years ago. Some of the papers submitted are still around, as well as the summary paper describing the results. But many papers are hard to find, and those that claimed to have source code available are hard to find --- i was able to get matlab sources for a few algorithms, but they somehow work on the example files, but mostly crash on my files.
It's a shame because I understand the idea of the paper, and have an excellent place to apply it, but I lack the DSP background, so I can't really rebuild the code from scratch -- so the work is not able to be used.
I'm not sure if I can find the exact paper anymore. This was in response to the Hurricane Challenge, a summary of results is available [1]. I tried to use code for uwSSDRCt available from the legacy page of the conference [2], under the link "Live and recorded speech modifier", direct download here [3].
The basic context is verification code delivery -- I'm playing pre-recorded samples of numbers to users, and can't control or sample the noise (either transmission or environmental), but would like to enhance intelligibility to reduce user effort, improve experience, and reduce costs.
