The GWX 2.0 speechpack can be partially corrected with a file compiled by Prologos- see
http://www.subsim.com/radioroom/show...=131792&page=2 This irons out some of the US voices in the speechpack- to use this, activate with JSGME after activating the German speechpack you are using. As time goes by no doubt all the US voices will be removed in a similar manner.
