public BuildBotLocaleResult buildBotLocale(BuildBotLocaleRequest request)
AmazonLexModelsV2Builds a bot, its intents, and its slot types into a specific locale. A bot can be built into multiple locales. At runtime the locale is used to choose a specific build of the bot.
buildBotLocale in interface AmazonLexModelsV2public CreateBotResult createBot(CreateBotRequest request)
AmazonLexModelsV2Creates an Amazon Lex conversational bot.
createBot in interface AmazonLexModelsV2public CreateBotAliasResult createBotAlias(CreateBotAliasRequest request)
AmazonLexModelsV2Creates an alias for the specified version of a bot. Use an alias to enable you to change the version of a bot without updating applications that use the bot.
For example, you can create an alias called "PROD" that your applications use to call the Amazon Lex bot.
createBotAlias in interface AmazonLexModelsV2public CreateBotLocaleResult createBotLocale(CreateBotLocaleRequest request)
AmazonLexModelsV2Creates a locale in the bot. The locale contains the intents and slot types that the bot uses in conversations with users in the specified language and locale. You must add a locale to a bot before you can add intents and slot types to the bot.
createBotLocale in interface AmazonLexModelsV2public CreateBotVersionResult createBotVersion(CreateBotVersionRequest request)
AmazonLexModelsV2
Creates a new version of the bot based on the DRAFT version. If the DRAFT version of
this resource hasn't changed since you created the last version, Amazon Lex doesn't create a new version, it
returns the last created version.
When you create the first version of a bot, Amazon Lex sets the version to 1. Subsequent versions increment by 1.
createBotVersion in interface AmazonLexModelsV2public CreateExportResult createExport(CreateExportRequest request)
AmazonLexModelsV2Creates a zip archive containing the contents of a bot or a bot locale. The archive contains a directory structure that contains JSON files that define the bot.
You can create an archive that contains the complete definition of a bot, or you can specify that the archive contain only the definition of a single bot locale.
For more information about exporting bots, and about the structure of the export archive, see Importing and exporting bots
createExport in interface AmazonLexModelsV2public CreateIntentResult createIntent(CreateIntentRequest request)
AmazonLexModelsV2Creates an intent.
To define the interaction between the user and your bot, you define one or more intents. For example, for a pizza
ordering bot you would create an OrderPizza intent.
When you create an intent, you must provide a name. You can optionally provide the following:
Sample utterances. For example, "I want to order a pizza" and "Can I order a pizza." You can't provide utterances for built-in intents.
Information to be gathered. You specify slots for the information that you bot requests from the user. You can specify standard slot types, such as date and time, or custom slot types for your application.
How the intent is fulfilled. You can provide a Lambda function or configure the intent to return the intent information to your client application. If you use a Lambda function, Amazon Lex invokes the function when all of the intent information is available.
A confirmation prompt to send to the user to confirm an intent. For example, "Shall I order your pizza?"
A conclusion statement to send to the user after the intent is fulfilled. For example, "I ordered your pizza."
A follow-up prompt that asks the user for additional activity. For example, "Do you want a drink with your pizza?"
createIntent in interface AmazonLexModelsV2public CreateResourcePolicyResult createResourcePolicy(CreateResourcePolicyRequest request)
AmazonLexModelsV2Creates a new resource policy with the specified policy statements.
createResourcePolicy in interface AmazonLexModelsV2public CreateResourcePolicyStatementResult createResourcePolicyStatement(CreateResourcePolicyStatementRequest request)
AmazonLexModelsV2Adds a new resource policy statement to a bot or bot alias. If a resource policy exists, the statement is added to the current resource policy. If a policy doesn't exist, a new policy is created.
You can't create a resource policy statement that allows cross-account access.
createResourcePolicyStatement in interface AmazonLexModelsV2public CreateSlotResult createSlot(CreateSlotRequest request)
AmazonLexModelsV2
Creates a slot in an intent. A slot is a variable needed to fulfill an intent. For example, an
OrderPizza intent might need slots for size, crust, and number of pizzas. For each slot, you define
one or more utterances that Amazon Lex uses to elicit a response from the user.
createSlot in interface AmazonLexModelsV2public CreateSlotTypeResult createSlotType(CreateSlotTypeRequest request)
AmazonLexModelsV2Creates a custom slot type
To create a custom slot type, specify a name for the slot type and a set of enumeration values, the values that a slot of this type can assume.

Deletes all versions of a bot, including the Draft version. To delete a specific version, use the
DeleteBotVersion operation.
When you delete a bot, all of the resources contained in the bot are also deleted. Deleting a bot removes all locales, intents, slot, and slot types defined for the bot.
If a bot has an alias, the DeleteBot operation returns a ResourceInUseException
exception. If you want to delete the bot and the alias, set the skipResourceInUseCheck parameter to
true.

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.
