First of all, I didn't understand English well, so I turned on the translator site.
I'm sorry about this.
I want to extract the voice clip from the Monster Strike update file, but there was no extraction method for it on either site.
I've uploaded some of sample sound files to mega.nz.
(I checked the bin file posted on mega.nz with HxDkor
and found that the file format was pk, I think it was a zip file.)
