android-alize-demo's Issues

Project Crashes when doing testing

Hi All,

When I am doing speaker verification test (from the "Test" button), sometimes the project will crash with the following error:

E/AndroidRuntime: FATAL EXCEPTION: main
    Process: fr.univavignon.alize.AndroidALIZEDemo, PID: 4603

The error will not occur everytime, it will occur suddenly during one of our testing. When the error occur, all the speakers model that we have trained will be gone.

Another error that we faced is when we are saving the new speaker model after recording, the program will crash in the same way, but with a different error message as shown below:

E/AndroidRuntime: FATAL EXCEPTION: addSamples Thread
    Process: fr.univavignon.alize.AndroidALIZEDemo, PID: 4975
    java.io.IOException: [ IOException 0xe16625f0 ]

Kindly advice on what could be causing this issue and how we can resolve it?

GMM parameters

Hi
I'm unable to figure out where you are specifying the GMM parameters like the number of Gaussians, initializations, and max iterations?
It would be great if you could help in that regard.
Thanks

Audio length

Hello,

I recently use the app, run OK. I can train my voice speaking between 5, 10 and 20 seconds.
The response is always negative over test (verification) and identification.

There is a good length for the training, verification and identification?
Something like:

Training: at least 20 seconds
Verification: at least 5 seconds
Identification: at least 10 seconds.

Thanks
