Tuning Alexa Skills language model schemas is a tedious trial and error process. Is there a way to bounce straight text off of Alexa with an API, just to see the JSON payload it would send to you? I'd like to be able to run text by the Alexa speech recognition engine (not audio) just to see how well my schemas are working, without having to wait for it to send it to my app and back, and to also be able to do it in a bulk fashion (i.e. - repeatedly calling the Alexa reco engine with a long list of sentences just to get a batch of JSON payloads showing the recognized intent and captured values back). This would also be a critical test to set up unit testing of schemas to see if new changes to a schema breaks old recognition results.
