Unihiker k10 flashing screen with speech recognition, help?

I'm new to the Unihiker k10, and am trying a code block in Mind+, and with variations of speech recognition, i keep getting a white flashing screen.

Can anyone test the code block below on theirs and see if theirs flashes too? As soon as i remover the set speech recognition block after the ‘wait 5 seconds’ block, i have the cached text Sleep display. I'm not sure if my unit is faulty?
