user-1: I have noticed in some YouTube videos that pauses in speech have been cut out. There are no pauses, and this makes the video easier to watch. 
How is this done? I have searched for this, but have only found tutorials on doing this manually, but there must be an automatic way for YouTube videos, I hope!
Here's an example of one of these videos:




user6571: You can use Laconia Trim for iOS 
or
LaconiaTrimVideo.com for online trimming
Both trims silence in video automatically.

user11789: On Avid ProTools when you are working on a video with an audio track, there are some hotkeys to automatically select all the audio parts where the waveform goes to zero or near to it.
Extending the selection also to the video track and cutting it off as well should do the trick, then you have just to use another hotkey to join the cutted pieces together without pauses in the middle.
I think this workflow could be applied on almost all the NLE (non linear editors) available around.

user6079: You are missing the point. He is not cutting out silence, he is keeping up a good hectic pace, making it hard to switch off while watching. 
Manually done. Why?

Telling a story, so you need to know what parts are relevant and what parts aren't
Sometimes even though there are silent parts, there are other visual things going on, like wild gestures, funny faces, a pause for dramatic effect.
Sometimes your cuts are NOT chronological in order. To make a story better you might pick clips or add clips from a completely different timeline or video.

The main issue you will find is the 'clicks' you here when you make the jump cuts. Normally you unlink the audio and video and you ONLY transition the audio part.
Hope that helps. Happy clipping.

user5928: The effect you are talking about is called jumpcut and it is particularly popular among vloggers.
As far as I know, there is no automatic way to do it although it would probably be possible to do from technological perspective.
However using jumpcuts has several functions.
You get rid of silence and squeeze as much information in short form as possible, keeping viewers attention.
Second important function is selection of your shots. While going through your material (shot usually in one take) you can discard stuff you don't want (even if you were talking at that point) and fundamentally alter the tone of your video.
This increased creative control is worth it considering that editing your video manually in this manner is very easy and won't take much time or effort.

tl;dr
It might be doable, but there is no user friendly solution now. Anyway I would suggest to do it manually for various reasons described in full answer.
