^^^^^ A decent SW broadcast list will be handy, if you have issue IDing the languages. A combinations of EiBi / Short-wave.info works well for me.
I can ID Chinese (can't understand it, but can ID the language reasonably well), and usually ID Korean and Japanese (although fast Korean often throws me off), can ID Viet and related languages (can't understand any of it, of course), and I can ID Russian, and sometimes one of the languages on the Indian Subcontinent. Malay is a toss up, as is Tagalog. Some of the other languages from more Central parts of Asia (Tibet, Afghanistan, etc.) are difficult for me to ID. For stations broadcasting in those languages, I have to rely on the lists and whatever knowledge of prop characteristics I have (which station might be more apt to make it over the Pacific).
But if you can figure out the language, and use a list, you'll often be surprised at what you heard. Also, some stations are jammed. So there's that wrinkle added to the mix. Earlier this a.m. I heard either China's CNR-11 or CNR-6 on 6010 khz playing a lot of soft ballads. It was too weak to really ID the language, but one of those two broadcasters had to have been what I heard (Brazil definitely wouldn't make it here at that hour). It was cool hearing it fading in and out over the ionosphere.
So although we here in the PNW have a few SW liabilities (high in latitude compared to the rest of the lower 48 states; away from Africa, Middle East, EU, South America, etc., where most SW seems to be happening during the evening), in the mornings we get a pretty good window to Asia.
