ios - Change OpenEars pitch dynamically (on the fly) -

-

i have ios app reads text using openears api. using latest version (1.2.5). can not figure out how change pitch while words being read ("on fly"). created slider control pitch. delegate fired slider changed. in delegate function, flitecontroller target_mean changed. intent have pitch change target_mean value changed. code follows:

-(void)saythemessage:(nsstring *)message {      // if there nothing there, don't try     if (message == nil)         return;      [self.oeeo setdelegate:self];      // going in label...     @try {          // set pitch, etc...         self.flite.target_mean = pitchvalue; // change pitch         self.flite.target_stddev = variencevalue; // change variance         self.flite.duration_stretch = speedvalue; // change speed          // it!         [self.flite say:message withvoice:self.slt];      }     @catch (nsexception *exception) {          if ([delegate respondstoselector:@selector(messageerror)])             [delegate messageerror];             }     @finally {      } }   -(void)changepitch:(float)pitch {      if ((pitch >= 0) && (pitch <= 2)) {          // save new pitch internally         pitchvalue = pitch;          // change pitch of current speaking....         self.flite.target_mean = pitchvalue;     }  }

any ideas?

openears developer here. can't change pitch on fly flitecontroller since pitch set before speech processed.

i have google question , find answer in day. know, data design many many table have list column,and mark pk , fk. why er-diagram have find this? data design process of designing database. main output of data design detailed logical data model of database. some people data design includes of needed logical , physical design choices , physical storage parameters needed generate design in data definition language. technically, database analysis, database analysts (dbas) trained do. while person can both data design , database analysis, these 2 different tasks. data design models data. database analysis takes model , applies 1 or more database engines (relational, hierarchical, nosql). a logical data model 1 of main outputs of data design. data model represented entity relationship diagram, or er diagram.
