You should be able to apply custom sounds like using mp3 or other format of sounds in game, prompting the option to select what audio you want the speaker to play, whilst interacting with it. Also, if players dont already have audio to use in game, they could use default random sounds as a trial version of the speaker. Perhaps console could use this feature but they can only use default sounds due to lack of compatibility with a tool to find files. Finally we should have the option to loop and play other sounds after a sound has finished its audio cue.
