Hello Matija,
I did a search on our website and although I didn’t find video lessons explaining these two specific pronunciation, I did find some other resources that I think will be helpful for you!
- Pinyin chart
This is a very useful page for learning pronunciation, and I recommend that you take a look at the pinyin chart and listen to the sounds carefully. I’ve listed out the pages that help explain the issue you have.
The [i] in shi does not produce the sound [ee], which you might be familiar with. Instead, the shi sound should be similar to the beginning of “shirt”, right before you pronounce the r sound. In fact, shi sounds exactly like [sh], so mastering one of them means you can pronounce both!
The e in she sounds like the “uh” in “duh”.
You can think of the she sound as the combination of shi and e.
If you still have trouble with the two sounds, you can check out the pinyin program series, and you will have more listening practice and examples.

Lastly, the Say it Right series is also a very helpful resource when it comes to pronunciation and tones. In the following episode, they explain some tricky initials including [s] and [sh].

Hope this helps!
