# DELETE /bots/{botId}/utterances/

`DELETE /bots/{botId}/utterances/`

Deletes stored utterances.

Amazon Lex stores the utterances that users send to your bot. Utterances are stored for 15 days for use with the [ListAggregatedUtterances](https://docs.aws.amazon.com/lexv2/latest/APIReference/API_ListAggregatedUtterances.html) operation, and then stored indefinitely for use in improving the ability of your bot to respond to user input..

Use the `DeleteUtterances` operation to manually delete utterances for a specific session. When you use the `DeleteUtterances` operation, utterances stored for improving your bot's ability to respond to user input are deleted immediately. Utterances stored for use with the `ListAggregatedUtterances` operation are deleted after 15 days.
