In church 100% all congregation speaks and knows only english. Someone speaks in Tongues in Russian. Unknown tongue to everyone present, even the speaker. ALL present need and Interpretation in English to know what was said. But both of the speakers are Speaking in Tongues

If it was a human language then it would "not require" the Holy Spirit's Gift of Interpretation.
Anyone could interpret it.
Since it requires the Holy Spirit's Gift of Interpretation, we know it's a Godly language, not a human language.
