Are there Christian groups that speak in tongues but as a policy require translation of the God-given language? If, therefore, the whole church comes together and all speak in tongues, and outsiders or unbelievers enter, will they not say that you are out of your minds?—1st Corinthians 14:23 (ESV)


There are passages in Scripture that caution those who speak in tongues to refrain if there is no one to translate. In my very limited exposure to the practice, I don't believe I've observed such a discipline. Are there specific cases of congregations / denominations with such rules?
There are denominations who emphasize the use of tongues, for example, Assemblies of God.
In such kind of Churches, there are occasions where someone would prophesy while speaking in tongues and the same person or sometimes others will interpret it.
There are many prophets who always start their prophetic words with tongues first and then interpret it again. I don't know why they always utter those tongues first and then interpret it instead of directly speaking out the words in their own language. I can only guess that they receive the message first in heavenly language, which we call it tongues, and at the same time God gives them the meaning also.
I don't know if there are any denomination which has a strict policy that tongues should have interpretations. What I know is that it is interpreted whenever there is a need. What I observed is that many times, those who speak in tongues also don't know what they are uttering but when it is required, God gives them the meaning.
