The odd thing about this old wives tale is that we have absolutely no evidence that the Holy Spirit has ever spoken a Gospel message through anyone. Most people will try to say that what the 120 were speaking on the Day of Pentecost was such a message but what the Holy Spirit was doing was to speak praise directly to God which the nearby crowd heard as disjointed sentences about the wonders of God.
If Peter had not provided a Gospel message in Aramaic then the day would have been lost, where the crowd would have dispersed thinking that these strange Galileans had maybe each rehearsed a few sentences in a particular language.
As tongues has absolutely no value with presenting the Gospel, where Paul says in 1Cor 14:2
" For one who speaks in a tongue does not speak to men but to God; for no one understands, but in his S/spirit he speaks mysteries", then maybe the following description by Peter Althouse regarding the purpose of tongues might help you to better understand why this act of proclamation through the Eschatological Spirit has been given to us; Althouse expands further on Pauls statement in 1Cor 14:16 where Paul says that when we pray in the Spirit (tongues) that we are "giving thanks in the Spirit"
"The Pentecost narrative of Acts 2 is an eschatological event, in which the coming of the resurrection Spirit renews the covenantal community in anticipation of the parousia, and tongues is a theophanic sign of divine self-disclosure like that of the burning bush in the calling of Moses and the giving of the Law. As an eschatological foretaste, speaking in tongues is a cry for liberation, a ‘cry of abandonment; which symbolizes the liberating force of the Spirit in breaking down racial, gender and class barriers. Glossolalia embodies an equalizing impulse in leveling all languages and human strivings, pointing to the inauguration of divine justice and mercy in its ''groaning" for the suffering of creation yearning for liberation".
How did you miss this part of Acts 2?
The Coming of the Holy Spirit
When the day of Pentecost arrived, they were all together in one place. And suddenly there came from heaven a sound like a mighty rushing wind, and it filled the entire house where they were sitting. And divided tongues as of fire appeared to them and resteda on each one of them. And they were all filled with the Holy Spirit and began to speak in other tongues as the Spirit gave them utterance.
Now there were dwelling in Jerusalem Jews, devout men from every nation under heaven. And at this sound the multitude came together, and they were bewildered, because each one was hearing them speak in his own language. And they were amazed and astonished, saying, “Are not all these who are speaking Galileans? And how is it that we hear, each of us in his own native language? Parthians and Medes and Elamites and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, Phrygia and Pamphylia, Egypt and the parts of Libya belonging to Cyrene, and visitors from Rome, both Jews and proselytes, Cretans and Arabians—we hear them telling in our own tongues the mighty works of God.” And all were amazed and perplexed, saying to one another, “What does this mean?” But others mocking said, “They are filled with new wine.”
1 Corinthians 14:1-33
Follow after charity, and desire spiritual gifts, but rather that ye may prophesy. For he that speaketh in an unknown tongue speaketh not unto men, but unto God: for no man understandeth him; howbeit in the spirit he speaketh mysteries. But he that prophesieth speaketh unto men to edification, and exhortation, and comfort. He that speaketh in an unknown tongue edifieth himself; but he that prophesieth edifieth the church. I would that ye all spake with tongues, but rather that ye prophesied: for greater is he that prophesieth than he that speaketh with tongues, except he interpret, that the church may receive edifying.
Now, brethren, if I come unto you speaking with tongues, what shall I profit you, except I shall speak to you either by revelation, or by knowledge, or by prophesying, or by doctrine? And even things without life giving sound, whether pipe or harp, except they give a distinction in the sounds, how shall it be known what is piped or harped? For if the trumpet give an uncertain sound, who shall prepare himself to the battle? So likewise ye, except ye utter by the tongue words easy to be understood, how shall it be known what is spoken? for ye shall speak into the air. There are, it may be, so many kinds of voices in the world, and none of them is without signification. Therefore if I know not the meaning of the voice, I shall be unto him that speaketh a barbarian, and he that speaketh shall be a barbarian unto me. Even so ye, forasmuch as ye are zealous of spiritual gifts, seek that ye may excel to the edifying of the church.
Wherefore let him that speaketh in an unknown tongue pray that he may interpret. For if I pray in an unknown tongue, my spirit prayeth, but my understanding is unfruitful. What is it then? I will pray with the spirit, and I will pray with the understanding also: I will sing with the spirit, and I will sing with the understanding also. Else when thou shalt bless with the spirit, how shall he that occupieth the room of the unlearned say Amen at thy giving of thanks, seeing he understandeth not what thou sayest? For thou verily givest thanks well, but the other is not edified. I thank my God, I speak with tongues more than ye all: Yet in the church I had rather speak five words with my understanding, that by my voice I might teach others also, than ten thousand words in an unknown tongue.
Brethren, be not children in understanding: howbeit in malice be ye children, but in understanding be men. In the law it is written, With men of other tongues and other lips will I speak unto this people; and yet for all that will they not hear me, saith the Lord. Wherefore tongues are for a sign, not to them that believe, but to them that believe not: but prophesying serveth not for them that believe not, but for them which believe. If therefore the whole church be come together into one place, and all speak with tongues, and there come in those that are unlearned, or unbelievers, will they not say that ye are mad? But if all prophesy, and there come in one that believeth not, or one unlearned, he is convinced of all, he is judged of all: And thus are the secrets of his heart made manifest; and so falling down on his face he will worship God, and report that God is in you of a truth.
Orderly Worship
How is it then, brethren? when ye come together, every one of you hath a psalm, hath a doctrine, hath a tongue, hath a revelation, hath an interpretation. Let all things be done unto edifying. If any man speak in an unknown tongue, let it be by two, or at the most by three, and that by course; and let one interpret. But if there be no interpreter, let him keep silence in the church; and let him speak to himself, and to God. Let the prophets speak two or three, and let the other judge. If any thing be revealed to another that sitteth by, let the first hold his peace. For ye may all prophesy one by one, that all may learn, and all may be comforted. And the spirits of the prophets are subject to the prophets. For God is not the author of confusion, but of peace, as in all churches of the saints.
