Yes, CV English, but it has NUMEROUS issues related to clarity and ease of use.
The reason CV Japanese works is that Japanese doesn't have ending consonants or dipthongs. But English does. Plus, English spelling is not at all consistent with how English is pronounced (the ough in "cough", "throughout" and "though" is pronounced differently for example), whereas Japaanese spelling is VERY consistent with pronunciation. So English banks use a variety of phoneme systems to make things work. And as such, in order to get GOOD English results, you need to play around with banks done in the larger CVVC family of reclists. If you really want ease of use and don't feel like fussing around with things, a CVVC bank (Japanese or English) with a presamp.ini + presamp itself might be your best bet.
However, English is NOT AT ALL recommended for beginners, mainly for the reasons listed above.
