I'm looking for an Android Application that I can record a voice message. Subsequently, when in a phone call, I'd like to push a button overlayed on the screen to play that audio back so the other person on the other end of the call hears the audio. It should sound as if I were speaking live. There has apparently been some difficulty doing this on older android phones, but I have a Samsung Galaxy Note 2. Preferably the app wouldn't need root access but if it does that's fine as well.
