How to add breaks into speech?

Adding breaks into Synthesia voice is becoming easier with SSML markup language.

Some of our voices now support a so-called SSML markup language. This markup has quite a few different tags but, for now, the most important one is the ability to instruct the voice to create breaks. 

Wherever you want an additional break in your text simply input (2s is an example here, you can specify time in seconds or milliseconds):

<break time="2s" />

Please note: the break can be up to 4 seconds long.

So, for example I have the following text in Synthesia:

Hey John! How are you doing today?

But I'm not happy with the default break after "John!". I can now simply input the following markup to fix it:

Hey John!<break time="200ms" />How are you doing today?
