  allowInterrupt: false,
};
```

## Properties

- `allowInterrupt`: boolean | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) — Indicates whether the user can interrupt a speech response from Amazon Lex.

- `messageGroupsList`: [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [IResolvable](/cdk/api/v2/docs/aws-cdk-lib.IResolvable.html) | [CfnBot.MessageGroupProperty](/cdk/api/v2/docs/aws-cdk-lib.aws_lex.CfnBot.MessageGroupProperty.html)[] (required) — A collection of responses that Amazon Lex can send to the user.

  Amazon Lex chooses the actual response to send at runtime.
