These two files will add "Pancho's" to the flightsim voices. You will need to download EditVoicePack by Lars Mellebjerg, available at most major FS sites. Note that these files will only work if you have installed the included AFCAD file. The file Panchos_agent.vcpmod will allow the tower to call itself "Pancho's" and the file Panchos_ICAO.vcpmod will allow flightplanning to "Pancho's" instead of to "Kilo Bravo Romeo November".

editvoicepack20.zip should find the voice program.
