Problem with pronunciation

Hi guys i have a problem with (ch) syllable words like: Ich - mochten - spreche is it pronounced (shh) or slighlty (khhh) !!! because sometimes here in the program pronounced (shhh) and sometimes (khhh)

It is pronounced both ways and it depends on the region just as English speakers in the US and UK pronounce words differently depending on geographic regions. I don't know that one is considered more proper than the other. Here's a blog post I found on line from a native speaker who says neither is correct but it is somewhere in between the two: 'Please note that the correct pronunciation of the "ch" sound is NEITHER "ck" nor "sh". For the soft German ch sound there is no equivalent in English so it cannot be explained in words, you just have to listen to it (for example here: http://dict.leo.org/ende?lp=ende&lang=de... - click on the loudspeaker icon). The closest explanation would be a cat's hissing sound, an audible exhaling. In some parts of the German Rhineland area, the local dialect for "ich" is "ish", and in the Berlin area, it is "ick". But this is only when people speak strong dialect, when they speak correct German, it is neither. Here's a cool test sentence / tongue twister: "Ich möchte mich nicht mit griechischer oder tschechischer Geschichte beschäftigen." (a German Rhinelander will never get this one right ...)

thank you very much Byron in fact i realize that correct pronunciation is not (ck) or (sh) but i can not explain that sound

The truth is you'll probably never learn to say it like a native speaker even after 20 years and that's OK. Most people find accents charming and you will be understood even if you can't say it exactly like a native. So, my suggestion would be to listen, practice, but don't get hung up on it.
