Most of my speech output are simple text so I am using type: "PlainText" for my responses.
Is there a way to read out individual letters without resorting to SSML?
I tried "'I' 'D'" for Id but it didn't work.
Try these (they sound good to me in alexa en voices). Tested in https://developer.amazon.com/alexa/console/ask/test//en_US/: "Voice and tone".
