Generate speech assets for new schema

[xtools-at]

Amazon changed how the intent schema and custom slots have to look like, it's one JSON object now:

would be great if you could update the speech asset generation!

Hi,
thanks for your comment. Since we have very small capacity to maintain this library we would really appreciate anyone who would implement this and create pull request. If not we will try to fix it as soon as we find some time for it.

I can do something about it. I wrote generation of language model part, without dialogs and prompts for now.

Therefore I hesitate to create PR

Also unit tests are something I don't have time for these days
