# Repeat Last Intent Pattern for user-friendly voice bots

April 26, 2022

When it comes to voice-based virtual agents, a user could run into the situation that they did not understand the last output message of the AI. This could be the case when the last message contained a lot of information or simply was too long to understand it.

In order to avoid these situations or better-said issues, one can make use of the **Repeat Last Intent** Pattern. This small Flow snippet executes the last triggered intent in Cognigy.AI and therefore all related Flow nodes:

In general, this pattern consists of two different parts:

1. The actual pattern and  
2. the rest of the Flow

The pattern, on the left side of the Flow, concentrates on checking if the current intent is **Repeat** and the **last intent** exists. So, if there was an intent triggered before, the AI says " _Sure, I repeat myself._" and uses a **Think** node to execute the last intents' nodes:

However, the left side of the Flow is only executed when the user triggers the mentioned **Repeat** intent, which is configured as the following:

Thus, such as displayed in the first figure, the user could write " _Can you please repeat this?_$" to execute this pattern. The right side of the Flow just executes the rest of AI's logic while the only specification is the **Add To Context** node which stores the current intent as the last intent in the Cognigy context for temporary storage purposes:

Ultimately, one could use this pattern as shown in the example at the top of a Flow to provide repeating messages in the conversation.
