A way to reduce stuttering

A way to reduce stuttering i know apps that makes stuttering go away 90%...those apps act like a mic so that you can hear your voice while talking and reduce stuttering by that way..type mic in playstore(appstore if IOS) and download any app, the bad thing is you must use wired headphones to use this method, otherwise you can't If anyone tried it tell me if it works or reduce the stutter by any chance
