When you’re creating an NLU model, you just upload (via the “import” button) your intents, slots, and sample utterances—if using the Alexa format, that’ll be a single JSON file; if using ours, it’ll be a .zip file containing a collection of TOML files.
That data is then used to train a TensorFlow Lite model—so you supply the training data, and the output is a TensorFlow Lite model, a vocab file, and a JSON metadata file for you to include in your app.
The Minecraft, Trivia, and HighLow models are samples we provide so you don’t have to train your own just to try out the NLU feature. You can download any of them (make sure to grab all three files) and include the paths to the files during setup (see here for the RN documentation on that). I’ll definitely look into putting a description of each of them on the site, but they’re conversions of sample Alexa skills provided by Amazon:
You can also download the
metadata.json for each model to see the intents it supports.
