Problem in adjust sound from text2speech

Does anyone know how to use this following function? I want to adjust speech. I already downloaded SAPI: speech SDK 5.1 but it's work and got error. This is source that I used text2speech http://www.mathworks.com/matlabcentral/fileexchange/11297-text2speech-tts

Emphasising (only for the SAPI version*) text2speech('You can EMPH emphasis /EMPH text.');

Silence (only for the SAPI version) text2speech('There will be silence now MSEC=''500''/ and speech again.');

I'm sorry for asking nonsense question but I have several downloaded on SDK 5.1

Ara - what is the error that you are observing? Please fully describe the problem that you are experiencing with the code that you have written.

it speech along the text include EMPH and /EMPH, it doesn't emphasize the text.
