## Available Channels

### Default AI Channel

The default AI channel is a universal channel and its settings correspond to the parameters in the [Say Node](https://docs.cognigy.com/ai/agents/develop/node-reference/basic/say). Use this channel to get more flexibility around different platforms.

### Alexa

- If the user triggers more than one Say Node in a Flow execution with the Alexa channel, the AI Agent concatenates each Say Nodes’ SSML or text outputs as one large SSML statement.
- If the Flow outputs more than one Card, the AI Agent sends only the last one.
- If the Flow outputs more than one Display configuration, the AI Agent uses only the last one.

The Alexa channel defines what and how an Amazon Echo-enabled system provides answers.
