Or you can check in your system tray, for me it says:
Tray Input Indicator - English (United States)
Or, if I switch to my German keyboard layout:
Tray Input Indicator - German (Germany)
I can press Jaws Key + F11 to bring up the system tray and press “T” to jump to that item and hear it read.
Of course I don’t usually do this because if I switch to German Eloquence speaks the letters I type in German.
