This is a little tricky to tell you without know what language are you working ...
Maybe a simple Filter can solve your problem or you can look at source code from Audacity are a cool code for noise removal.
Another choice is use Sox by command line to process your voice and use noiseprof to try remove noise.
WebRTC has an Android API with a very good noise suppresing module.
