At the moment, I am using an old Pi to convert text to speech and I've wired the output of it to headphones and glued headphone earpiece next to mic input on a cheap Alexa Flex
All works well
But when I saw about this text command - I thought - I'll be able to send my desired command direct to the Flex 
But (as with everything to do with this sort of thing) it doesn't work for the thing I want it work for
i.e
If I say tell my pi to say "Alexa, ask cheerlights to change to colour red" - my pi speaks this into my Flex and the flex responds correctly
But if I send the text command "ask cheerlights to change to colour red" - I'm getting "cheerlights isn't responding"
So it's failed straight out of the box for me 
I'll stick with my "acoustic coupler" method for now
