java - CMUSphinx never recognizes any word from audio files -
sphinx doesn't seem recognize or process audio files accepts audio stream spits out empty array(speechresult result). feel there isn't issues audio file i'm using because i've tried several , doesn't work on of them. have audio file know works? , there stands out causing stream not produce transcription?
