Dashbot is a service that helps you track your Alexa skill’s analytics more comprehensively than the Amazon Developer Portal. If your requirements are not satisfied with the data provided by the Dev Portal, then I would suggest using Dashbot.
There are three core technologies that power Alexa. It’s not just Alexa, either. All voice assistants such as Siri, Google Home, etc. use these important technologies. They are Automatic Speech Recognition (ASR), Natural Language Understanding (NLU), and Text To Speech (TTS).
