TracksBoard.ItemSpeechFromFileAdd method |
|
Remarks
Adds a speech item, obtained from a text file, to the audio stream previously created through the TracksBoard.Create method. The text file can be eventually modified at a later time through the TracksBoard.ItemSpeechFileSet method.
In case you should need to add a text to speech stream from a simple string of text you may use the TracksBoard.ItemSpeechFromStringAdd method.
The text file 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.
