Mistery of "-rl" sound unveiled

I finally have unveiled the mistery of the "-rl" sound. The secret is to expand the larynx so that there are more rooms in mouth to move my tongue. According to the "American Accent Training", a book+cds I ordered from the internet, English utilizes throat for speech generation. I have overlooked this fact until now. To utilize throat, I must expand my throat, not constricting it like Korean or other asian languages.

This finding for me is very significant since the most vocal unclarity is caused by my ambiguous "r", and "l" sound. The worst has been "r" and "l" sounds put together, such as "curl", "girl", "world", etc... From this findings from yesterday, I am now expanding my throat whenever I speak English. This speech synthesis technique is extensively used by many public speakers such as teachers, professors, and presenters. This is thought to be due to easiness of making loud sounds at minimal efforts. Kristine Baur, my Math 349 professor uses this technique.

Everything is getting better and so is my speech.
