hi, I'm using pocketsphinx on android, the thing is that my phone would make some noise mixed with speech during the recording process(not always), in that case I can only get the result when the speaker is very close to my phone's mic so the speech is loud enough, but what I want is to keep the distance between speaker and mic at least 10cm and recognizable, well this may cause noise louder than speech and unrecognizable(see attached), what should I do instead of closer to the mic or raise voice? any advice would be much appreciated.
Its better to switch to kaldi on android, more accurate.
Thx, I'll try if kaldi could help with my situation.
is it your application playing or some other application?
my application, any difference?
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
If you know what your application plays you can try to cancel that noise programmatically with acoustic echo cancellation algorithm. That will leave just the speech. Not very trivial though.

I don't seem to understand the 'quote' operation, how embarrassing.
