TracksBoard.ItemSpeechFromStringAdd method |
|
Remarks
Adds a speech item, contained inside a string, to the audio stream previously created through the TracksBoard.Create method. The text string can be eventually modified at a later time through the TracksBoard.ItemSpeechStringSet method.
In case you should need to add a text to speech stream from contents of a text file you may use the TracksBoard.ItemSpeechFromFileAdd method.
The string of text may eventually contain XML markups: see the MSDN documentation for a tutorial about XML markup syntax.
Important note about items overlapping
Overlapping of two items on the same track is now allowed so, in case the new item should cause an overlapping and upon space availability, the new item will be automatically moved to the next track or to the previous track; if both previous and next tracks should in any case suffer an overlapping, a new track will be automatically inserted on the nearest position.
