TalkingMouthDemo
TalkingMouthDemo is a brief demonstration in Objective-C / Cocoa of the basic NSSpeechSynthesizer/Delegate support to sync the spoken phonemes with images of individual mouth shapes to produce an animated mouth.
Details
I posted an explanation of this code and the methodology behind it in the post titled “Talking Face Speech Synthesizer Demo“.
Usage
Only relevant parts are highlighted here. The full code (including the
-imageForPhoneme:
method as well as the example phoneme images) are available in the project.
- (IBAction)speak:(id)sender
{
// Start speaking
[synthesizer startSpeakingString:[textField stringValue]];
}
- (void)speechSynthesizer:(NSSpeechSynthesizer *)sender
willSpeakPhoneme:(short)phonemeOpcode
{
// Set the right image for the incoming phoneme opcode
if (phonemeOpcode && [[self phonemes] count])
[imageView setImage:[self imageForPhoneme:phonemeOpcode]];
}
- (void)speechSynthesizer:(NSSpeechSynthesizer *)sender
didFinishSpeaking:(BOOL)success
{
// Finished speaking, so silence is golden
[imageView setImage:[[self phonemes] objectAtIndex:0]];
}
- (NSImage *)imageForPhoneme:(short)phonemeOpcode
{
return [[self phonemes] objectAtIndex:phonemeOpcode];
}
{
// Start speaking
[synthesizer startSpeakingString:[textField stringValue]];
}
- (void)speechSynthesizer:(NSSpeechSynthesizer *)sender
willSpeakPhoneme:(short)phonemeOpcode
{
// Set the right image for the incoming phoneme opcode
if (phonemeOpcode && [[self phonemes] count])
[imageView setImage:[self imageForPhoneme:phonemeOpcode]];
}
- (void)speechSynthesizer:(NSSpeechSynthesizer *)sender
didFinishSpeaking:(BOOL)success
{
// Finished speaking, so silence is golden
[imageView setImage:[[self phonemes] objectAtIndex:0]];
}
- (NSImage *)imageForPhoneme:(short)phonemeOpcode
{
return [[self phonemes] objectAtIndex:phonemeOpcode];
}
