I am testing a Sphinx4 app on Windows (XP Pro) and notice that for the app to recognize any of the (JSGF) speech patterns I am using, I have to manually adjust the gain on my microphone in the Volume Controls provided by that GUI | Advanced.
Is there a way to boost the gain of the attached microphone, regardless of type, given that I am accessing the audio stream using the Microphone class provided by Sphinx4, such that my users don't need to play with their Volume Control GUI?
TIA,
elm
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
i am sorry to say, but there is no way currently using the sp4 codebase.
But don't give up hope, i've already implemented a sp4 DataProcessor which aims in the direction to perform online gain normalization. (If someone knows some publications about this topic i would be very interested). I hope to be able to provide it as soon as possible to the sp4 codebase.
Best regards,
Holger
