how to do pause after paragraph while textToSpeech

i have a text which is used for textToSpeech.
i want to do a pause in the text which is readed from the dragon mobile SDK for iPhone. the text is without the SSML. only blanc text.

What kind of charactars can i use for pause? I know that after a " . " is a pause, i tried to do two . like ". ." but doesnt work.

How can i do pause after paragraph?

Example:

Lorem ipsum dolor sit amet, consectetuer adipiscing elit.
//Do here a long pause from 3 seconds
Aenean commodo ligula eget dolor. Aenean massa. Cum sociis natoque penatibus et

Solution

i have found it. no way out to use SSML. and SSML is incredible :)
have to use the break tag in SSML, see here: http://www.w3.org/TR/speech-synthesis/#S3.2.3
