Play wav file after hypothesis

[kelvinKW]

Hello!

Is there any method that can allow OpenEars, after recognition
, playing a wav/mp3 file after hypothesis?

Thank you!

Welcome,

This is outside of OpenEars’ API since it isn’t intended to be a general-purpose audio toolkit, but you can just play back a WAV using AVAudioPlayer after receiving a hypothesis.

Thanks for your answer!

But how can I modify the source code ?
Is it modify at self.heardtextview.text?

[Halle Winkler]

You can put AVAudioPlayer playback in – (void) pocketsphinxDidReceiveHypothesis:(NSString *)hypothesis recognitionScore:(NSString *)recognitionScore utteranceID:(NSString *)utteranceID.

Sorry, I need another help.

The situation is that, I want to produce different mp3 sound for each recognition.

Example is that:

When pocketsplinx receive hypothesis A, after recognition, it will play
A.mp3

When pocketsplinx receive hypothesis B, after recognition, it will play
B.mp3

How can I modify the source code to let such happen?

thank you!

It’s the same answer as my first answer above. OpenEars doesn’t play audio files, so you don’t have to modify OpenEars’ source code in order to do that. You will put the logic for playing audio files in your own app code, and you can use OpenEars’ API to decide when to trigger that code in your app.

“You will put the logic for playing audio files in your own app code, and you can use OpenEars’ API to decide when to trigger that code in your app.”

Can you explain this with more detail?
Since I am quite confusing about this.

thank you

Hi,

Sorry, that is getting into more general questions about how to use Objective-C to develop apps. As much as I wish I could assist with those more general questions, I only have the resources to offer help with OpenEars here.
