The accounts in Acts 2,8,10 and 19 do confirm tongues is the outward evidence of the initial indwelling by the Holy Ghost. In each case the evidence proved the experience had actually taken place.
I start with the Samaritan account because it is a prime example of a truth many fail to realize. Please don't skim over this first question as it has profound significance. How did Philip and others know the Samaritans had not received the Holy Ghost? I hope you will ponder on that. The Samaritans believed the gospel and submitted to water baptism in the name of Jesus, yet did not receive the Holy Ghost until days later:
"Now when the apostles which were at Jerusalem heard that Samaria had received the word of God, they sent unto them Peter and John:
Who, when they were come down, prayed for them, that they might receive the Holy Ghost:
(For as yet he was fallen upon none of them: only they were baptized in the name of the Lord Jesus.)
Then laid they their hands on them, and they received the Holy Ghost.
And when Simon saw that through laying on of the apostles' hands the Holy Ghost was given, he offered them money," Acts 8:15-18
At Pentecost - Upon being indwelt by the Holy Ghost all spoke in tongues:
"And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance...
Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear." Acts 2:4, 33
The Gentiles - The same evidence that accompanied the giving of the Holy Ghost was tongues:
"And they of the circumcision which believed were astonished, as many as came with Peter, because that on the Gentiles also was poured out the gift of the Holy Ghost.
For they heard them speak with tongues, and magnify God. Then answered Peter,"
"And as I began to speak, the Holy Ghost fell on them, as on us at the beginning." Acts 10:45-46, 11:15
The 12 Ephesians - The same evidence reveals the experience occurred:
"And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied." Acts 19:6
