That's awesome :D Good luck with your coursework! I do my best to match the sounds to the [url=http://www.internationalphoneticalphabet.org/ipa-sounds/ipa-chart-with-sounds/]relative IPA phonetic sound[/url] (this may be familiar), which helps me to think about the sounds without any language bias. I figure all languages are ultimately tied to this universally, so it helps to keep an objective mindset. Saying them out loud on repeat helps me figure out what part of the mouth was most likely used so I can figure out what is actually being said (I was especially having trouble with k/g for example). It takes a lot of repetitive listening of a group of phonetic sounds, so it absolutely helps to have as clean a recording as possible. I can't really give any advice as far as matching the phonetics other than putting the ear to the grind for long periods of hours. It took me a good few solid weeks to get these sounds, so it's by no means easy. I'm not sure whether or not it helps that I have no idea what I'm doing, entirely making it up as I go; just been feeling for it. There's absolutely a possibility there's a better way of doing this, but I've no training in the matter, so hey, who knows, you might be able to do a far better job than me soon enough :)
