I am trying to create an audio file from a speech utterance with FliteController, and it works as expected:

[self.fliteController say:message withVoice:self.slt];
NSData *voiceData = self.fliteController.speechData;

I can save that NSData to a file and plays perfectly.

However, I’d like to avoid playing the message, but I don’t see how can I “load” the NSString message without playing it.

I’ve tried with the following properties:

[self.fliteController setQuietFlite:YES];
[self.fliteController setNoAudioSessionOverrides:YES];

But the audio file is played anyway.

Any ideas?

Thank you very much in advance.

Sorry, this isn’t supported in the API.
