 In this overview, you learn about the benefits and capabilities of intent recognition. An intent is something the user wants to do: book a flight, check the weather, or make a call. With intent recognition, your applications, tools, and devices can determine what the user wants to initiate or do based on options. You define user intent in the intent recognizer or conversational language understanding (CLU) model.

 ## Pattern matching
 
 The Speech SDK provides an embedded pattern matcher that you can use to recognize intents in a strict way. This is useful for when you need a quick offline solution. This works especially well when the user is going to be trained in some way or can be expected to use specific phrases to trigger intents. For example: "Go to floor seven", or "Turn on the lamp" etc. It's recommended to start here and if it no longer meets your needs, switch to using [CLU](#conversational-language-understanding) or a combination of the two.

 ## Patterns vs. Exact Phrases
 
 There are two types of strings used in the pattern matcher: "exact phrases" and "patterns". It's important to understand the differences.
