Thank you for referring me to MartinK's modrana thread as I`d completely forgotten about the discussions they were having about the use of Mbrola.But,unfortunately,we cannot legally use it.Mikko did email what we thought was a dead email account but several hours later received a legal letter that runs for over 15 pages from an American legal company based in New York that specializes in copyrights.This company does exist .Apparently one of the original developers of the code sought legal protection,and was granted,a copyright to avoid unauthorized use.They readily threatened legal action but in the same sentence,they offered to sell us the `module`,as they refer to it, for a 5 figure sum !!!!.

So,its back to the drawing board

Let this be a lesson to all the community....Look before you leap
