Why does 背く sound like そむふ in this sentence?


The clip and subtitles:

<http://clyp.it/fmzowhxt> 組織の命令に **背く** という事は どういう事か お前は わかってない！

So why is 背く being pronounced like that? I don't hear a く at all and hear a ふ
instead.

Also, maybe the following is related(if not, I'll remove it and put it in its
own question):

<http://clyp.it/g01r22ei> 自宅からウィルスを送ってたら、先走った刑事にウィルスが揃う前に捕まっちまうところだった。  
I'm hearing おくfってたら instead of of おくってたら

<http://clyp.it/hv3yjmeo> バトー！ ナナオはそこを経由して分割したウィルスを送ってきてる  
Similarly I'm hearing おくfってきて(And no ～る, but I guess that's a question for
another day.)

Edit: Revised to clarify that I'm not hearing a full mora but just an 'f'
sound in 送fって. I would describe it as a single syllable "okf", but the last
time I tried to describe Japanese in terms of syllables(yak'sok'), I was
chastised and felt great shame..




When a speaker pronounce `く`, speakers breathe out the air because of the
vowel `u`.

It is _not impossible_ to hear that a speaker pronunce `く` as `く(ふ)` or just
`ふ` in some situations.

But it's certain that `く` is written `ku` in Romaji and it doesn't have
multiple moras.
