Detailed description

This API is not part of the public API, which can be found in sdk api Plug-in.

Here, TTS APIs define the common data types required by TTS. This type covers text data segmentation and Speech Style. The TTS common module must be used in the TTS client application.

Header file

LIBRARY         nssttscommon.lib

Sample Code

TTS style information

This attribute can be used to set the synthesis language, the reader's age, and so on.

TTtsStyle               iStyle;
 TTtsStyleID             iStyleId;
 // Use high quality TTS
 iStyle.iQuality = ETtsQualityHighOnly;
 // Use language and speaker set in Speech application. 
 // Also speaking rate and volume is set according to Speech app. 
 iStyle.iLanguage = KTtsUndefinedLanguage;
 // Add style
 iStyleId = iTtsUtility->AddStyleL( iStyle );// where iTtsutility is CTtsUtility

Text Segmentation Information

This class records segment information

TTtsSegment             iSegment;
 iSegment.SetStyleID( iStyleId ); // Sets the style for a segment. 
 //The style cannot be deleted during the lifetime of this object.
 iSegment.SetTextPtr( iParsedText->Text() );//Sets a text pointer. 
 //The text cannot be deleted during the lifetime of this object.

CTtsParsedText

Here, the CTtsParsedText Class records the TTS decomposition text. This class has text and related phoneme sequences (used for pattern recognition) and segmented information.

Add paragraph

Adds or inserts a new paragraph. The paragraph must be added to the correct position. That is, the text and phoneme sequence must follow each other. You can delete this section after the function returns.

CTtsParsedText* iParsedText = CTtsParsedText::NewL();
 // Set text
 iParsedText->SetTextL( KText1 );
 iParsedText->AddSegmentL( iSegment, 0 );

Delete the number of paragraphs and paragraphs

if ( iParsedText->NumberOfSegments() > 0 )
 {
 // Remove existing segment from parsed text structure
 iParsedText->DeleteSegmentL( 0 );
 }
