Yes, I installed using the tutorial instructions.

Actually the issue is resolved. The linker errors are in the tests build target in the sample app. After deleting the tests target, the sample app builds fine with SaveThatWaveDemo.

[zhousean]

Just followed the instructions on the web site,
https://www.politepix.com/savethatwave/

1. Open up the OpenEars™ Sample App in Xcode. Drag your downloaded SaveThatWaveDemo.framework into the OpenEars™ sample app project file navigator.
2. Open up the Build Settings tab of your app or OpenEarsSampleApp and find the entry “Other Linker Flags” and add the linker flag “-ObjC”. Do this for debug and release builds.

No, I haven’t tried the VoiceChat audio mode. I actually don’t know anything about this mode. Could you give a bit more details about it?

[zhousean]

Thanks Halle.

It we cannot use score, is there anyway to dynamically recalibrate OpenEars to the changing background?

[zhousean]

My main goal is to improve the recognition accuracy in a noisy environment. Between Rejecto or RuleORama, which one is your recommendation?

[zhousean]

My tests show that the Slt goes to the car audio if it was set to speak via the phone earpiece and the phone is connected to car bluetooth. The Slt doesn’t go to the car audio if it was set to speak via the phone’s loud speaker.

I have another framework in my app which has a delegate method to set the loud speaker status.

[zhousean]

OK, I think I found where these settings are.

[[OEPocketsphinxController sharedInstance] setVadThreshold:0.5];
[[OEPocketsphinxController sharedInstance] setLatencyTuning: 1];

And this is what I see at the header file.
/**Speech/Silence threshhold setting. You may not need to make any changes to this, however, if you are experiencing quiet background noises triggering speech recognition, you can raise this to a value from 2-5 to 3.5 for the English acoustic model, and between 3.0 and 4.5 for the Spanish acoustic model. If you are experiencing too many words being ignored you can reduce this. The maximum value is 5.0 and the minimum is .5. For the English model, values less than 1.5 or more than 3.5 are likely to lead to poor results. For the Spanish model, higher values can be used. Please test any changes here carefully to see what effect they have on your user experience.*/
@property (nonatomic, assign) float vadThreshold;

I guess I will try to set it to 3.5?

[zhousean]

Actually, I was not able to find vadThreshold. And how to set setLatencyTunning? Do you have a document about the parameters?

[zhousean]

Halle, I meant 40% of battery used by all apps. With my app running, the battery will not last 24 hours. It is almost completely drained in the late afternoon.

I will try to tune vadThreshold.

[zhousean]

After upgrading to OpenEars 2.03, the problem disappeared. Thanks Halle!

[zhousean]

Here is a more complete log file. I didn’t see any RapidEars settings. Delegate methods I used the following two:

– (void) rapidEarsDidReceiveLiveSpeechHypothesis:(NSString *)hypothesis recognitionScore:(NSString *)recognitionScore {
NSLog(@”rapidEarsDidReceiveLiveSpeechHypothesis: %@”,hypothesis);
}

– (void) rapidEarsDidReceiveFinishedSpeechHypothesis:(NSString *)hypothesis recognitionScore:(NSString *)recognitionScore {
NSLog(@”rapidEarsDidReceiveFinishedSpeechHypothesis: %@”,hypothesis);
}
