Thank you. You are nice.
Here is my feeback:
1. the /ts/ sound in United States needs to be improved;---I was confident for this pronounciation. Still do not know what is wrong. If it is possible, can you let me know how to pronounce it?
2. you add /l/ sound in several words, lik, "company", and "industry", where the first syllabble in "company" is pronounced as /vl/ (note the "v" indicates the updidedown letter); and /vl/ in the second syllable of "industry". ----do you mean I pronounced them as com-pvl-ny, and in-dvl-stry?
3. you added /i/ sound in the second syllable in word "business"; ---I really thought it was bizinis:)Thank you a lot.
4. when pronouncing the /er/ sound the so-called /R/ sound, you should finish the vowel sound well before pronouncing the "r" sound, it seems you pronounced it too abruptly and too quick. (hard for me to explain). --I know what you mean. I got it.
5. "employer", /cy/ sound is missing, it should be pronounced as /cie/ (here, the "c" is the mirrored letter sound, and the "e" is the upsidedown one).---got it. Just pronounce like :imploi-year
6. "official", the emphasis should be in the second syllable, and you stressed the first syllable.---you are right.
Your comments are very welcome and helpful. Thank you again.
