I’ve made my own version of a GlaDOS voice for TomTom sat-navs. I saw the one for Garmin and thought I could do better. ;) I used a Text-to-speech website and then ran the lines through Melodyne to create the GLaDOS effect. This voice contains distances in both meters and yards. You can download the voice here: tinyurl.com or here: www.megaupload.com or here: dl.dropbox.com
