Including voicepack modifications with your addon

Follow this procedure to include modifications ATC speech engine of Microsoft Flight Simulator X and Lockheed Martin’s Prepar3D® simulation software with your own flight simulator addons.

  1. Create the modifications in EditVoicepack and export them to vcpmod files. Alternatively export exiting modifications where available. Please refer to the EditVoicepack XL documentation for details on how to create or export modifications.

  2. Zip the modifications and send them by e-mail to api@editvoicepack.com. clearly indicating in the e-mail subject you are requesting EditVoicepack modifications for an addon product. In the e-mail, clearly state:

    • The name of the addon developer - an individual, a company or a group. (Required)
    • The name of the product the modifications will be included with. (Required)
    • The website of the addon developer. (Optional)
    • The website of the addon product. (Optional)
    • An icon for the addon developer and/or product. This icon must be in an XAML DrawingImage format. The typical bitmap based icon will not work as EditVoicepack (where the icon will be displayed) is fully vector based. (Optional)

  3. Include the signed files you get back with your addon in one of the following locations. Notice that you can choose to place the files directly in the listed location, or in a subfolder named "ATC Modifications":

    • Scenery:
      • The root folder of the scenery.
      • The Texture subfolder.
      • The Scenery subfolder.
      Note Note
      The modification will not be installed if it's located under the "Scenery" folder of the flight simulator directory. This folder is reserved for scenery included with the flight simulator and should not be used for addon scenery. Notice the scenery must have been added to the Scenery Library in the flight simulator before the modification can be installed.
    • Aircrafts:
      • The root folder of the aircraft (the folder containing "sim.cfg" or "aircraft.cfg").
      • The Texture.X folder containing the texture for the aircraft (where X match a definition for the texture defined in "sim.cfg" or "aircraft.cfg").
      Note Note
      The installer will automatically locate aircrafts installed into the standard flight simulator directory structure: "<flightsimulatorroot>\SimObjects\<objectsfolder>\<aircraftfolder>". It will also locate aircrafts in SimObject folders defined in the current users "fsx.cfg" or "Prepar3d.cfg" file, but it can not locate aircrafts only present in the "fsx.cfg" or "Prepar3D.cfg" of other users on the system.
    • In the rare case it's not possible to use one of the locations mentioned above, the files can also be placed in a subfolder of "<flightsimulatorroot>ATC Modifications". Please ensure the files are placed in subfolders uniquely identifying the product they belong to.

  4. Ensure the EditVoicepack Installer is executed as part of your installation procedure. This can be done in several ways:

    • Integrate the EditVoicepack installer into your .NET based installer or configuration utility.

      For details, see: VoicepackUpdater

    • Instruct the users to run an EditVoicepack installer.

      This approach should only be used if your addon does not come with an installer.

      The example installer supplied with the EditVoicepack Installer API can be redistributed for this purpose, or you can create your own based on the sample code included with the EditVoicepack API.
