Is there audio? Anyhow, Jack, native English speakers often use reductions in natural speech. The word “is” is usually contracted to “’s” in spoken English. If the preceding word ends in /s/ or /z/, there should be a schwa in between, but you might not hear that in rapid speech, in which case the final S of “States” could possibly merge (or seem to merge) with the following “’s”. As far as “currently”, Americans will usually pronounce the T very lightly (possibly as a glottal stop), and may even omit it in rapid speech. This is because the N, T, and L all have more or less the same primary place of articulation. The E in “currently” would normally be reduced to a schwa, and could easily disappear in rapid speech. The R would almost certainly be pronounced by most Americans — if you can’t hear it, you may need to familiarize yourself more with the R sound. as far as the N in “currently”, given its proximity to the L, and the tendency to confuse N and L in your part of China, it’s likely you just didn’t hear it. This is the kind of stuff I teach in my students. By learning to speak more like a native, not only does their speech become more comprehensible, but their ability to understand what they hear increases dramatically.
