Yes but its usally not shown during a service
The phenomenon of a demon speaking in tongues refers to the belief that a demonic entity is able to communicate in languages unknown to the speaker. This is often associated with possession or spiritual influence.
One fundamental difference they have from other Christian faiths is that they don't believe you receive the Holy Spirit immediately at the time of accepting Jesus Christ as Lord and Savior. They believe that happens some time later and is manifested at that time by speaking in tongues (unknown heavenly languages).
Speaking in tongues, also known as glossolalia, is a practice in some religious traditions where individuals speak in a language that is unknown to them, often believed to be a form of communication with a higher power or a manifestation of spiritual experience. The purpose of speaking in tongues is often seen as a way to connect with the divine, express deep emotions, or receive spiritual guidance.
"To speak in tongues" refers to a story in The Bible, where the believers started to spontaneously speak in languages they hadn't known before.
For the most part Christians. It's spoken of in the bible early in the book of Acts following the reception of the holy spirit to believers after the final accession of Christ. I Corinthians 12 and 14 also mention "speaking in tongues" as one of the manifestations available by a Christian believers holy spirit. This is considered perfect prayer that bypasses an individuals understanding and is to be done in private unless interpreted in a worship meeting. Despite the many religions and sects who speak in tongues many fail to actually live up to the concluding exhortation concerning the proper operations of this manifestation in the church. I Corinthians 14:40 "Let all things (context emphasizes speaking in tongues) be done decently and in order" -not acting crazy and being emotionally out of bounds.Many Christians in Pentecostal-type denominations speak in tongues. Though some choose not to.
The term is glossolalia, also known as speaking in tongues. The speaking in actual foreign languages is known as xenoglossy. See http://en.wikipedia.org/wiki/Glossolia and http://en.wikipedia.org/wiki/Xenoglossy
In the book of Acts and some of the epistles, the writers of the Bible describe a miraculous speaking in foreign languages, or "speaking in tongues." In the book of Acts, those so enabled by the Holy Spirit fluently spoke languages they had never learned or studied, in order to preach about Jesus to people who spoke another language, to praise God, or to prophesy. In his first letter to the Corinthians, the apostle Paul says "if I speak in the languages of men and of angels, but do not have love, I am only a resounding gong or a clanging cymbal." Because of this, some Christians believe that the gift of tongues also enables people to speak the languages of angels, whereas other Christians believe that Paul is using hyperbole, and that the gift of tongues only applied to human languages.
You're probably thinking of "glossolalia", though it's not really synonymous with Pentecost. Glossolalia is basically speaking in tongues or an unknown language, which is what they did on the Day of Pentecost -- and many do today. Another word for it is xenoglossia.
Some religions believe that they have the power to speak in tongues which no one but God can understand. This is what is called Priestcraft. There are two ways which are acceptable to God and both are gifts from Him called The Gift of Tongues where a person may be gifted to be able to speak in the language of a people when he has never been able to do so before. When he has delivered his message the gift leaves him.. The other is when a message is being given in the speakes own tongue, the listeners hear him in their own language. Any other way of Speaking in Tongues is of Satan, and usually comes out of the speakers mouth as gibberish, which not even God can understand.
Speaking in tongues is a religious experience. Somebody will talk in tongues because God (the Holy Spirit) is talking through them and the only way people can understand them is when God uses someone to interpret what is said (unless somebody is talking in a different language and somebody else who knows that language can understand them).
Speaking in tongues is supposedly evidence of the Holy Spirit, since no human can really understand what is being said.The apostle Paul was dismissive of those who claimed to speak in tongues, although he was not prepared to alienate those who claimed this ability. He indicated a preference for prophecy, since this at least might be useful. In 1 Corinthians 14:4, Paul says "Whoever speaks in a tongue builds himself up, but whoever prophesies builds up the church." He then goes on to explain what he sees as the futility of speaking in tongues, summarising this in verse 19: "but in the church I would rather speak five words with my mind, so as to instruct others also, than ten thousand words in a tongue."
