[Freeswitch-users] Split string and play charachters

Hello, Is there an application which plays the characters of a string individually? Or have some sort of split function which splits a string into characters and then manually map the 'character_name' to an existing audio file? For instance: //String: 1234567890 //Split the string Playback: 1.wav Playback: 2.wav Playback: 3.wav Etc Can this be done in the XML dialplan or do I need to use some scripting language to control the dialplan?
