The Bible itself reports that on the Day of Pentecost, the Holy Spirit descended on the disciples and they spoke to the gathered pilgrims in their own languages, rather than just Aramaic or Greek. So that’s what a Holy Spirit inspired message looks like: no matter the language of the person delivering it, the receiving person receives it in their own language. No translator needed.
Does that show that the Bible is not inspired by the Holy Spirit, because it needs translators?
So
"So" is a typo.
That is not at ALL what happened on the day of Pentecost. It was not the hearing that was inspired, but the speakers themselves.
Let’s look at the text:
Acts 2:4 – 12 " 4 All of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them.
AC 2:5 Now there were staying in Jerusalem God-fearing Jews from every nation under heaven. 6 When they heard this sound, a crowd came together in bewilderment, because each one heard them speaking in his own language. 7 Utterly amazed, they asked: "Are not all these men who are speaking Galileans? 8 Then how is it that each of us hears them in his own native language? 9 Parthians, Medes and Elamites; residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia, 10 Phrygia and Pamphylia, Egypt and the parts of Libya near Cyrene; visitors from Rome 11 (both Jews and converts to Judaism); Cretans and Arabs–we hear them declaring the wonders of God in our own tongues!" 12 Amazed and perplexed, they asked one another, "What does this mean?"
The pronoun "them" in v.4 refers to those gathered in the upper room mentioned in v. 1 – 3. (Probably the same 12 mentioned in Acts 1:15). It also states that they SPOKE in other tongues as the Spirit ENABLED THEM … NOT that the hearers HEARD the speaking as the Spirit enabled.
There is no textual or exegetical justification for claiming that it was the hearers who were enabled to hear in their own language rather than the speakers who were enabled to speak in other languages.
Thus it was the church of that day, inspired by The Holy Spirit, who translated the message of the gospel into the languages of those gathered to listen.
And this remains the job of the church, which is why we translate the Bible into different languages.
