I read about the new Speechcons for the Alexa Skills Kit here:
However, on testing them out I found, despite no mention of this in the documentation, that these appear to be another feature which is US only. I tested the following example:
<speak><say-as interpret-as=\"interjection\">Well well! Booyah.</say-as></speak>
With the language as English (UK) it speaks it in a monotone, it is only when I switch to English (US) that it speaks it more expressively.
Why is this US only, and when can we expect to be able to use this in the UK?
