EditVoicepack offers a simple interface to edit the file containing the ATC communication used in Microsoft Flight Simulator 2004: A Century of Flight. It is possible to change the phraseology as well as add airline callsigns, airports, and aircraft types. EditVoicepack already contains thousands of ready made entries; and is able to download new entries from a central server. It also allows you to accelerate the existing voices for a more realistic experience and better handling of traffic dense environments.
A Flight Simulator X compatible version is currently being developed, and a community technology preview is available for download. Please visit the development wiki page for details.
Users of Microsoft Flight Simulator 2004: A Century of Flight should use the following version: Download: EditVoicepack 3.1 (1.8MB)
Users of Microsoft Flight Simulator 2002 should use the following version (this version is no longer actively developed or supported): Download: EditVoicepack 2.2 (697 KB)
Please notice that you will also need the Microsoft .NET Framework to run EditVoicepack. EditVoicepack 3.1 will direct you to the download page at Microsoft when you run the installer. For EditVoicepack 2.2, please find the link in the supplied readme file.
Please use the following resources to find information on how to use EditVoicepack.
If you do not disable the automatic update notifications, EditVoicepack will contact this server each time it is started to check if it is up to date. If there is a new version of the program, it will inform you. It will also download new modifications uploaded by other users. The update can also be started manually from the about box if you prefer not having EditVoicepack contact the server each time it's started. Please notice that updates are no longer being distributed to EditVoicepack 2.2.
In case your Flight Simulator computer is not connected to the Internet, the Download Offline Update Files page still allows you easy access to all the benefits of EditVoicepack's update system.
The Modification Request Tracking page allows you to see voicepack modifications uploaded to the server. All uploaded modifications will be reviewed before they are either accepted or rejected. Accepted modification will automatically be available for download though the online or offline updates.
You can help adding new modifications to EditVoicepack - for example by including the airfields around the areas you frequent in Flight Simulator. The more people adding modifications, the better EditVoicepack will be for all of us.
EditVoicepack (the software as well as the updates) is completely free, even though it is taking me several hours a week to maintain. If you think EditVoicepack is worth paying for, you can always donate some money on my paypal account so I can cover some of my cost from buying FS addons.
I do not have the time to maintain an extensive list of Flight Simulator related sites and utilities, but I do recommend visiting Project AI if you are interested in adding real-life traffic to Flight Simulator.
