Question to Catholics about Charismatics who speak in tongues?

What can you say about Catholic Charismatic groups? I have been to some of their prayer meetings (they call it "praise and worship" meeting) and I have seen them speak in tongues like the evangelicals. They also conduct Life in the Spirity Seminars where participants recieve the gifts of the Holy Spirit like praying in tongues, healing, prophecy, etc. I know there are priests who are members of these Charismatic groups. Is the Charismatic movement in accordance with Catholic teachings?
