HRN has got it's own skill on the Amazon smart speaker making it much easier for everyone to install the feature.
All you have to do is activate the skill by either saying 'Alexa enable skill' then when she asks which skill you reply with 'Hospital Radio Norwich'. You can also activate HRN by using your alexa app on your mobile phone. Go to add skill then search for Hospital Radio Norwich, select our app (shows our logo) then click 'enable skill'. Once this is done you only have to say 'Alexa play Hospital Radio Norwich'
