@Generated(value="com.amazonaws:aws-java-sdk-code-generator") public interface AmazonLexRuntimeAsync extends AmazonLexRuntime
AsyncHandler
can be used to receive
notification when an asynchronous operation completes.
Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
AbstractAmazonLexRuntimeAsync
instead.
Amazon Lex provides both build and runtime endpoints. Each endpoint provides a set of operations (API). Your conversational bot uses the runtime API to understand user utterances (user input text or voice). For example, suppose a user says "I want pizza", your bot sends this input to Amazon Lex using the runtime API. Amazon Lex recognizes that the user request is for the OrderPizza intent (one of the intents defined in the bot). Then Amazon Lex engages in user conversation on behalf of the bot to elicit required information (slot values, such as pizza size and crust type), and then performs fulfillment activity (that you configured when you created the bot). You use the build-time API to create and manage your Amazon Lex bot. For a list of build-time operations, see the build-time API, .

Future<DeleteSessionResult> deleteSessionAsync(DeleteSessionRequest deleteSessionRequest)
Removes session information for a specified bot, alias, and user ID.
deleteSessionRequest
- Future<DeleteSessionResult> deleteSessionAsync(DeleteSessionRequest deleteSessionRequest, AsyncHandler<DeleteSessionRequest,DeleteSessionResult> asyncHandler)
Removes session information for a specified bot, alias, and user ID.
deleteSessionRequest
- asyncHandler
- Asynchronous callback handler for events in the lifecycle of the request. Users can provide an
implementation of the callback methods in this interface to receive notification of successful or
unsuccessful completion of the operation.Future<GetSessionResult> getSessionAsync(GetSessionRequest getSessionRequest)
Returns session information for a specified bot, alias, and user ID.
getSessionRequest
- Future<GetSessionResult> getSessionAsync(GetSessionRequest getSessionRequest, AsyncHandler<GetSessionRequest,GetSessionResult> asyncHandler)
Returns session information for a specified bot, alias, and user ID.
getSessionRequest
- asyncHandler
- Asynchronous callback handler for events in the lifecycle of the request. Users can provide an
implementation of the callback methods in this interface to receive notification of successful or
unsuccessful completion of the operation.Future<PostContentResult> postContentAsync(PostContentRequest postContentRequest)
Sends user input (text or speech) to Amazon Lex. Clients use this API to send text and audio requests to Amazon Lex at runtime. Amazon Lex interprets the user input using the machine learning model that it built for the bot.
The PostContent
operation supports audio input at 8kHz and 16kHz. You can use 8kHz audio to achieve
higher speech recognition accuracy in telephone audio applications.
In response, Amazon Lex returns the next message to convey to the user. Consider the following example messages:
For a user input "I would like a pizza," Amazon Lex might return a response with a message eliciting slot data
(for example, PizzaSize
): "What size pizza would you like?".
After the user provides all of the pizza order information, Amazon Lex might return a response with a message to get user confirmation: "Order the pizza?".
After the user replies "Yes" to the confirmation prompt, Amazon Lex might return a conclusion statement: "Thank you, your cheese pizza has been ordered.".
Not all Amazon Lex messages require a response from the user. For example, conclusion statements do not require a
response. Some messages require only a yes or no response. In addition to the message
, Amazon Lex
provides additional context about the message in the response that you can use to enhance client behavior, such
as displaying the appropriate client user interface. Consider the following examples:
If the message is to elicit slot data, Amazon Lex returns the following context information:
x-amz-lex-dialog-state
header set to ElicitSlot
x-amz-lex-intent-name
header set to the intent name in the current context
x-amz-lex-slot-to-elicit
header set to the slot name for which the message
is eliciting
information
x-amz-lex-slots
header set to a map of slots configured for the intent with their current values
If the message is a confirmation prompt, the x-amz-lex-dialog-state
header is set to
Confirmation
and the x-amz-lex-slot-to-elicit
header is omitted.
If the message is a clarification prompt configured for the intent, indicating that the user intent is not
understood, the x-amz-dialog-state
header is set to ElicitIntent
and the
x-amz-slot-to-elicit
header is omitted.
In addition, Amazon Lex also returns your application-specific sessionAttributes
. For more
information, see Managing Conversation
Context.
