How I do ? I have followed the tuotrial and said to record some sound and it woudl have appeared but nothing it still doesn't show anything ... how do I do to show up the text?

did you click save after record? Also you have to set a GetisID for the dialogue? Also try ticking the "Force Subtitle" box in the the topic info window.
Make sure you have a starting topic,

Hope this helps

Also, the recorded sound needs to be long enough for you to read it. The subtitles stay no screen for the length of time that the sound lasts. So 1 sec of sound means the subtitles will only appear for 1 second.
