Obviously what happened on the day of Pentacost was miraculous, not the least of which was the fact that spectators heard the apostles praising God in a variety of local langauges presumably unknown to the apostles.
Nothing in the New Testament garantees this will happen, or denies that it can't happen again.
I've heard other similar stories, but too many non believers persist in the notion that tongues are for preaching to others when clearly that is not the intent.
But every story I have ever heard of this has the bystanders all saying that the speaker was praising God.
I 'm not sure I'm following what you're saying here, maybe it's the pumpkin pie fog.
