When a NLU matches to an intent it outputs two pieces of information, the main intent it matched to and its confidence. Confidence shows how likely a certain intent is, between 0-100%.  

In the Voiceflow settings you can adjust the the Intent Confidence Threshold depending on how confident you'd like to match.

A higher threshold reduces false positives, meaning matches to an unrelated intent.

A lower threshold reduces false negatives, meaning missed matches.
