In case you haven’t heard it yet: The voice beta testing program is now open to the public as Linden Lab writes on their blog. There’s also a new version out now which has a new speech indicator which also indicated if you are just listening and thus making it easier to distinguish between people with voice activated and those without. So download it here and keep talking 🙂
PS: Apparently they added also some new options for the key used for enabling push-to-talk and one if them is the ‘ (the key above the tab key). Of course with a german keyboard it’s not above the tab key, it’s the ^ instead. So international issues are still issues unfortunately (and the ^ is of course quite underused here, too, so it would make sense to have this as an option, too).
