Hi Simon. VoiceTrack scrolling is supported in English, French, Russian, German, and Spanish. There are some more platform-specific language options on Android and on iOS, but those are the 5 common to all of our apps. For example, in the iOS PromptSmart+ mobile app it will scroll also in Italian, Chinese, and Turkish. Let us know if you have any other questions, and of course we'd be grateful for any feedback if you decide to try it out.
