Cant found my create language in the game

Did you mean to type "How do I share my custom speech bank in Worms Reloaded? I can't find my created bank in the game."?

Custom speech banks are stored in "<steam folder>\steamapps\common\worms reloaded\Audio\Default\Win\CustomBanks". There you can find any speech banks you've made to freely share, or put new speech banks you've found online to use.
