How to get ML dictation involving multiple languages.

Question

Hello all I just upgraded my MBPearly2011 from Snow Leopard to Mountain Lion yesterday.
With the upgrade, I found that I can now type by talking (probably nothing new to you guys I suppose). I use Japanese as the main language on this computer, but as you can see with this post, I also frequently use English to type, chat with friends. Talk-typing (or whatever the verb is) in Japanese is not a huge problem and I can do it pretty smoothly and I'll get better once I get used to it, although there are problems involving changing to the correct kanji character and such, but that's a different story.
My main problem for now is being able to talk-type in English with the Japanese settings. The only "English words" the mic is picking up are major Apple products such as iMac and iPhone. I tried speaking English three ways: the native way, the typical Japanese way, and the katakana way (you'll understand if you know the language). All three don't work. The katakana is the best alternative, but I can't turn in an English essay with foreign text. Only select Japanese will understand what I am trying to say, and they'll probably give up during the first sentence because it isn't in any way formal writing.
The best solution I can think of is changing the language on the computer back to English through System Preferences → Languages, but I type in both Japanese and English interchangeably, and I am too lazy to change the settings every time (with a necessary restart? no way).
Is there a way to make English talk-typing possible in a Japanese language setting without going to System Preferences every time I need to switch a language?
