It annoys me when people use Github for blogging because that‘s what they‘re used to, especially if it‘s not the best medium. What do you think, are elaborate markdown tables the best way to show how to pronounce something, or… a wav file?
I read through the post and agree with you that I still don't have a clear understanding of the correct sounds, but I doubt I would have gone sound by sound trying to hear the differences.
Overall my takeaway is that there are common names and sound that are worth remembering, I checked a few like Nguyen, and will probably check others when coming across some Chinese name that reminds me of the article.
