1. Don't include the words in the reclist (that never comes out good in UTAU, vocaloid it may have work but that's a complete diferent engine)
2.You have to treat delta's list as if it's a lite list made by a japanese user (and lite list are "harder" to deal with because as a someone who's new to English CVVC, you're going to have troubles regardless, since you don't know how to use a lite list , and trust me most people who end up making them can make a lot of mistakes especially when it comes to the CC CV blends)
3.Using CC's and CV's and VC's instead of CCV's and VCC's is hard work and no one knows how to do them well and consitnatly.
For ClV (such as blue and clock), you need a to record a CLl eg bl with "l" acting as a vowel, and blend a short version (no more than around 60) in length of the Cl, with a lV (like lu) and you have what ever word you wanted.
To do CrV's (like brain and crook), then you do the same thing as ClVs but instead of Cl, use C3,(like b3 and ch3).
For VC's it's usuasly easier as they tend to be straight forward eg to do "ends" you'd do [en] [ndz] or [en] [nd][dz]
Now for the words you asked in Teto's bank they'd be:
Blue=[- bl] [lu]
Breeze=[- b3] [- ri] [iz]
Strength(this is going to sound funny, it's because the str sound is not the same as the st3 sound, it's more shch3)= [- str][- re] [e n] [k] [T]
girl=[- g3] [3l]
please=[- pl][li][iz]/[is] (depending on how you say please it's either s or z)
(Oh and 3 is the same in both delta's and CZ's lists it's the "er" sound in worker.)
Hopefully it wasn't to confusing (but's it hard to help you using just text and words)
