How can I get confidence score (or probability) in pocketsphinx app

[qiqi]

Hi, dear all,

I am trying to get a measure to see how accurate my recognition result is in pocketsphinx app (not the one on PC). I have checked several literature. It seems that the confidence score or probability can do this. Is that right?

Another question, how can I get this measure in the app? Does the code provide any API that I can get the number?

Thank you.

Could anyone help me with this question, please?

Thank you.

Does the code provide any API that I can get the number?

Yes, there is such API. You can check API reference for details.

Could you tell me where the API reference is? I am talking about the pocketsphinx application in Android. So far I didn't see any API manual about that.

Thank you so much!

Thank you! But could you help me. How can I call this method in developing android application?

[Nickolay V. Shmyrev]

for (Segment seg : recognizer.getDecoder().seg()) {
           System.out.println(seg.getWord()  + "  " + seg.getProb());
}

[Goncharova Valentina]

Please, tell me, will this work with a search in grammar? I use a grammar search and get seg.getProb () equal to 0

[Nickolay V. Shmyrev]

No, it does not work with grammar search.

Thank you very much for your help
