Maybe we can have English listening tods on saturday, instead of silly airplane fighting:p
Ok joking, but the problem is that poor quality of AH voice is not helping who is trying to understand other languages; more, sure , ATC comm is in English language, but they follow standard language rules;in AH voice everyone speaks freely, saying things the way they came in his mind without any fixed rule, and this makes things more difficult for little or partial english speakers.
Last you are commonly using the term "english", but for a person who uses english as a second language there are more than one "english"; I mean sometimes when I hear a UK person or a Texan person or an Australian one, talking the same "english language" , they sound like more than one languageat my ears.
We are here to improve our english too, anyway:)
