WavPack might be suitable for such an application...
Do you have any "feeling" for how high bitrate you would need for a "high quality" voice transmission?

Specifically, there are speech samples at 24 and 32 kbps. You may get slightly worse results than those depending on how you address your low-latency requirement, but they will give you an idea. It's obviously no where near as good as a dedicated speech codec (or Opus), but should be easier for a less powerful CPU.
Thanks! Do you need to be a "DSP math expert" to use the lib's?
