Amazon Lex Model Building V2

2021/09/22 - Amazon Lex Model Building V2 - 2 new api methods

Changes  This release adds support for utterances statistics for bots built using Lex V2 console and APIs. For details, see: https://docs.aws.amazon.com/lexv2/latest/dg/monitoring-utterances.html

ListAggregatedUtterances (new) Link ¶

Provides a list of utterances that users have sent to the bot.

Utterances are aggregated by the text of the utterance. For example, all instances where customers used the phrase "I want to order pizza" are aggregated into the same line in the response.

You can see both detected utterances and missed utterances. A detected utterance is where the bot properly recognized the utterance and activated the associated intent. A missed utterance was not recognized by the bot and didn't activate an intent.

Utterances can be aggregated for a bot alias or for a bot version, but not both at the same time.

Utterances statistics are not generated under the following conditions:

  • The childDirected field was set to true when the bot was created.

  • You are using slot obfuscation with one or more slots.

  • You opted out of participating in improving Amazon Lex.

type nextToken

string

param nextToken

If the response from the ListAggregatedUtterances operation contains more results that specified in the maxResults parameter, a token is returned in the response. Use that token in the nextToken parameter to return the next page of results.

    • nextToken (string) --

      A token that indicates whether there are more results to return in a response to the ListAggregatedUtterances operation. If the nextToken field is present, you send the contents as the nextToken parameter of a ListAggregatedUtterances operation request to get the next page of results.

DeleteUtterances (new) Link ¶

Deletes stored utterances.

Amazon Lex stores the utterances that users send to your bot. Utterances are stored for 15 days for use with the 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.
