I want to compare two audio files one file is already store in app and the other file is detect by background sound of user's phone like: music or FM and compare both files if the word which store in first audio is matched with background song's lyrics then it will immediately mute the system. I don't understand how can i detect the lyrics and compare both file.
How could i do that comparison in order to get a match? What is the process to follow in this type of apps?
If anyone have answer of my question and relevant code also then please share with me
