The above link is lesson one in a four lesson on-line basic Hebrew course.
 
You can click on each Hebrew letter and each form of the letter to hear how it is pronounced.
 
Note that some letters have dots and are pronounced with the hard sound of the letter.  Without the dot they have the soft sound.  Kaf and peh fall into this category and you can hear that the final version has the soft sound of the letter.
 
If you do all the parts of each of the 4 lessons it is a fun way to practice the Hebrew letters and learn a few words.   Also you can go to the home page where they have some interesting introductions.
 
It is a basic course and a good place to start.  It may be helpful even if you already know some Hebrew.
 
Shalom, Roberta.
