Every person is different, and each one will have their own way of expressing themselves. For that reason, it's quite hard to cover all the possible phrases that the users might use to represent an intent.
In those cases, when the phrase isn't mapped to an intent, the fallback intent will be called.
DialogFlow will store all the phrases that were used, and display with a warning those that aren't mapped.
Then is very easy to map those phrases to your intents and make your action smarter.
