Well they should be proud of their origin and heritage. But here is a story - I was studding telecommunications in the university. One of the things we learned while working with A29 (purely analogue switches from end to end) was that noise and latency were very important.
Latency was not a problem until it was below 100 ms then up to 500 ms it gradually decreased the quality of the conversation but not in significant way. Now at the 500ms mark something funny happened. The person thought that the other party had not heard what he said and begin repeating it while the beginning of the other person answer begin his phone. The comprehensiveness of the conversation decreased dramatically.
It was the same with noise - from a point on it was terrible. I think that accented speech could be considered as noise.
A friend of mine was doing project with Huawei a few years ago - the Chinese team was with strong accents and he was with very strong Eastern European too. They had trouble communicating in English.
