PESQ is useless for vocoders in general, but there's an ancient quality assessment tool that does a good job. I believe it's called "ears" :-) Seriously, subjective listening is really the only decent way I've found to evaluate vocoders. I've not come across any remotely useful objective metric.
Thank you for taking the time to answer!
What are good ways of assessing quality achieved by the LPCNet Vocoder? I found that PESQ results are way worse than the quality I experienced myself, with ratings constantly in the range between 1 and 2 (which is to be interpreted as hardly/barely understandable). Has anyone experienced similar problems with PESQ? What are the alternatives?
