Interaction Model - Intent Schema

This is the Intent Schema for sending intents up to Amazon Lambda. You can see there's only really one intent, SpeedTestIntent.
  "intents": [
      "intent": "SpeedTestIntent"
      "intent": "AMAZON.HelpIntent"
      "intent": "AMAZON.StopIntent"

Interaction Model - Sample Utterances

What can you say to Alexa, and what will it do? Pretty easy, with only one Intent:
SpeedTestIntent what's my internet speed
SpeedTestIntent what is my internet speed
SpeedTestIntent What's my last speed
SpeedTestIntent What was my last speed
SpeedTestIntent last speed
SpeedTestIntent What was my last download
SpeedTestIntent check speed

Lambda Code

Here's your lambda Code
This skill returns data from a thinkspeak channel.  In my case, this is a regular speed test.

Ask alexa "what's my internet speed" to get the last download speed.
