Ok. Thank you very much for your time. I do want to let you know that this one has baffled me for quite some time. So I got the PocketSphinx and LibSphinx source codes, and I ran those independent of the OpenEars platform with the audio file content sent directly to “acmod”, “fe” and “fe_noise.c” and I see the same exact behavior as with OpenEars; “fe_track_snr” function shows SNR high for the first 70 frames then comes down to silence and works accurately for the remainder of the audio data in the file.

Anyway, I think that this level of discussion is outside the scope of this support forum. Once again, thank you very much for taking the time to support. I will revisit after I run the application on a real device, or if I run into any other OpenEars challenges.

Thank you.

I did not test on a real device yet. I am still in simulation world and it will be a few weeks before moving to a real device. I have read many of your posts and I understand the difference between simulator mode and real device mode. I can wait and see what happens when I run on a real device.

One last observation, the logs that I gave you are for a recognition on a file without using the audio driver. So I am not sure if using a simulator or not will affect recognition on your provided audio file. If anything I would expect that the front end audio speech detector of PocketSphinx to work flawlessly, using a simulator or not, on a file that has 3-4 seconds of silence in its beginning.

Is it possible that you run this simple test case on the file with the test function that I mentioned above using a simulator and send me the output log?

Thank you much.
