You are correct in your point that in every case of "baptism of the Spirit" in the Bible where a gift is mentioned, tongues is present. We also find this to be nearly always so, as well, in actual spiritual practice 2,000 years later. When people are baptized in the Holy Spirit, either when saved or later, most people receive this "baby talk" gift. But this does not mean it is always so, and we have Scriptural proof of it.
1 Cor 12:29-30 (NIV) Are all apostles? Are all prophets? Are all teachers? Do all work miracles? Do all have gifts of healing? Do all speak in tongues? Do all interpret?Since the answer to each of the above questions is clearly "no", we see that some receive gifts from the Holy Spirit and clearly do not speak in tongues. I know a few myself, so experience matches Scripture.
I for one, was hoping for a greater gift. <smiles> I ended up babbling like so many others. As the least of the gifts, still it is/was a start, and I thank God for His grace in this. I am sure it is just what I needed in my lofty zeal.
Thus, we must be clear about the Holy Spirit's prerogative to give out whatever gifts He chooses (Heb 2:4), but also acknowledge that in Scripture--as in experience--He nearly always choose tongues first.
Heb 2:4 (Wey) ... by gifts of the Holy Spirit distributed in accordance with His own will.
1 Cor 12:31 (NIV) But eagerly desire the greater gifts.
1 Cor 12:4 (KJV) Now there are diversities of gifts, but the same Spirit.
1 Cor 12:29-31 (Phi) As we look at the body of Christ do we find all are his messengers, all are preachers, or all teachers? Do we find all wielders of spiritual power, all able to heal, all able to speak with tongues, or all able to interpret the tongues? You should set your hearts on the best spiritual gifts...
1 Pet 4:10 (TEB) Each one, as a good manager of God's different gifts, must use for the good of others the special gift he has received from God.
1 Cor 14:12 (Jer) ... Since you aspire to spiritual gifts, concentrate on those which will grow to benefit the community.
1 Cor 12:31 (Jer) Be ambitious for the higher gifts.
