extends AwsClient
```
Service client for accessing Amazon Lex Runtime Service. This can be created using the static builder() method.
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, .

                                      LexRuntimeException
```
    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.
    Parameters:
    
    postContentRequest -
    requestBody - The content to send to the service. A RequestBody can be created using one of several factory methods for various sources of data. For example, to create a request body from a file you can do the following.
    RequestBody.fromFile(new File("myfile.txt"))
    See documentation in RequestBody for additional details and which sources of data are supported. The service documentation for the request content is as follows '
    User input in PCM or Opus audio format or text format as described in the Content-Type HTTP header.
    
    You can stream audio data to Amazon Lex or you can create a local buffer that captures all of the audio data before sending. In general, you get better performance if you stream audio data rather than buffering the data locally.
    '
    responseTransformer - Functional interface for processing the streamed response content. The unmarshalled PostContentResponse and an InputStream to the response content are provided as parameters to the callback. The callback may return a transformed type which will be the return value of this method. See ResponseTransformer for details on implementing this interface and for links to pre-canned implementations for common scenarios like downloading to a file. The service documentation for the response content is as follows '
    The prompt (or statement) to convey to the user. This is based on the bot configuration and context. For example, if Amazon Lex did not understand the user intent, it sends the clarificationPrompt configured for the bot. If the intent requires confirmation before taking the fulfillment action, it sends the confirmationPrompt. Another example: Suppose that the Lambda function successfully fulfilled the intent, and sent a message to convey to the user. Then Amazon Lex sends that message in the response.
    '.
    
    Returns:
    
    The transformed result of the ResponseTransformer.
    
    Throws:
    
    NotFoundException - The resource (such as the Amazon Lex bot or an alias) that is referred to is not found.
    
    BadRequestException - Request validation failed, there is no usable message in the context, or the bot build failed, is still in progress, or contains unbuilt changes.
    
    LimitExceededException - Exceeded a limit.
    
    InternalFailureException - Internal service error. Retry the call.
    
    ConflictException - Two clients are using the same AWS account, Amazon Lex bot, and user ID.
    
    UnsupportedMediaTypeException - The Content-Type header (PostContent API) has an invalid value.
    
    NotAcceptableException - The accept header in the request does not have a valid value.
    
    RequestTimeoutException - The input speech is too long.
    DependencyFailedException - One of the dependencies, such as AWS Lambda or Amazon Polly, threw an exception. For example,
    
    If Amazon Lex does not have sufficient permissions to call a Lambda function.
    
    If a Lambda function takes longer than 30 seconds to execute.
    
    If a fulfillment Lambda function returns a Delegate dialog action without removing any slot values.
    BadGatewayException - Either the Amazon Lex bot is still building, or one of the dependent services (Amazon Polly, AWS Lambda) failed with an internal service error.
    
    LoopDetectedException - This exception is not used.
    
    SdkException - Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
    
    SdkClientException - If any client side error occurs such as an IO related failure, failure to get credentials, etc.
    
    LexRuntimeException - Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this type.

    This is a convenience which creates an instance of the PostContentRequest.Builder avoiding the need to create one manually via PostContentRequest.builder()
    Parameters:
    
    postContentRequest - A Consumer that will call methods on PostContentRequest.Builder to create a request.
    requestBody - The content to send to the service. A RequestBody can be created using one of several factory methods for various sources of data. For example, to create a request body from a file you can do the following.
    RequestBody.fromFile(new File("myfile.txt"))
    See documentation in RequestBody for additional details and which sources of data are supported. The service documentation for the request content is as follows '
    User input in PCM or Opus audio format or text format as described in the Content-Type HTTP header.
    
    You can stream audio data to Amazon Lex or you can create a local buffer that captures all of the audio data before sending. In general, you get better performance if you stream audio data rather than buffering the data locally.
    '
    responseTransformer - Functional interface for processing the streamed response content. The unmarshalled PostContentResponse and an InputStream to the response content are provided as parameters to the callback. The callback may return a transformed type which will be the return value of this method. See ResponseTransformer for details on implementing this interface and for links to pre-canned implementations for common scenarios like downloading to a file. The service documentation for the response content is as follows '
    The prompt (or statement) to convey to the user. This is based on the bot configuration and context. For example, if Amazon Lex did not understand the user intent, it sends the clarificationPrompt configured for the bot. If the intent requires confirmation before taking the fulfillment action, it sends the confirmationPrompt. Another example: Suppose that the Lambda function successfully fulfilled the intent, and sent a message to convey to the user. Then Amazon Lex sends that message in the response.
    '.
    
    Returns:
    
    The transformed result of the ResponseTransformer.
    
    Throws:
    
    NotFoundException - The resource (such as the Amazon Lex bot or an alias) that is referred to is not found.
    
    BadRequestException - Request validation failed, there is no usable message in the context, or the bot build failed, is still in progress, or contains unbuilt changes.
    
    LimitExceededException - Exceeded a limit.
    
    InternalFailureException - Internal service error. Retry the call.
    
    ConflictException - Two clients are using the same AWS account, Amazon Lex bot, and user ID.
    
    UnsupportedMediaTypeException - The Content-Type header (PostContent API) has an invalid value.
    
    NotAcceptableException - The accept header in the request does not have a valid value.
    
    RequestTimeoutException - The input speech is too long.
    DependencyFailedException - One of the dependencies, such as AWS Lambda or Amazon Polly, threw an exception. For example,
    
    If Amazon Lex does not have sufficient permissions to call a Lambda function.
    
    If a Lambda function takes longer than 30 seconds to execute.
    
    If a fulfillment Lambda function returns a Delegate dialog action without removing any slot values.
    BadGatewayException - Either the Amazon Lex bot is still building, or one of the dependent services (Amazon Polly, AWS Lambda) failed with an internal service error.
    
    LoopDetectedException - This exception is not used.
    
    SdkException - Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
    
    SdkClientException - If any client side error occurs such as an IO related failure, failure to get credentials, etc.

```
    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.
    Parameters:
    
    postContentRequest -
    
    sourcePath - Path to file containing data to send to the service. File will be read entirely and may be read multiple times in the event of a retry. If the file does not exist or the current user does not have access to read it then an exception will be thrown. The service documentation for the request content is as follows '
    User input in PCM or Opus audio format or text format as described in the Content-Type HTTP header.
    
    You can stream audio data to Amazon Lex or you can create a local buffer that captures all of the audio data before sending. In general, you get better performance if you stream audio data rather than buffering the data locally.
    '
    
    destinationPath - Path to file that response contents will be written to. The file must not exist or this method will throw an exception. If the file is not writable by the current user then an exception will be thrown. The service documentation for the response content is as follows '
    The prompt (or statement) to convey to the user. This is based on the bot configuration and context. For example, if Amazon Lex did not understand the user intent, it sends the clarificationPrompt configured for the bot.

      intentName set to the intent name in the current context
      
      slotToElicit set to the slot name for which the message is eliciting information
      
      slots set to a map of slots, configured for the intent, with currently known values
    - If the message is a confirmation prompt, the dialogState is set to ConfirmIntent and SlotToElicit is set to null.
    - If the message is a clarification prompt (configured for the intent) that indicates that user intent is not understood, the dialogState is set to ElicitIntent and slotToElicit is set to null.
    In addition, Amazon Lex also returns your application-specific sessionAttributes. For more information, see Managing Conversation Context.
    
    This is a convenience which creates an instance of the PostTextRequest.Builder avoiding the need to create one manually via PostTextRequest.builder()
    Parameters:
    
    postTextRequest - A Consumer that will call methods on PostTextRequest.Builder to create a request.
    
    Returns:
    
    Result of the PostText operation returned by the service.
    
    Throws:
    
    NotFoundException - The resource (such as the Amazon Lex bot or an alias) that is referred to is not found.
    
    BadRequestException - Request validation failed, there is no usable message in the context, or the bot build failed, is still in progress, or contains unbuilt changes.
    
    LimitExceededException - Exceeded a limit.
    
    InternalFailureException - Internal service error. Retry the call.
    
    ConflictException - Two clients are using the same AWS account, Amazon Lex bot, and user ID.
    DependencyFailedException - One of the dependencies, such as AWS Lambda or Amazon Polly, threw an exception. For example,
    
    If Amazon Lex does not have sufficient permissions to call a Lambda function.
    
    If a Lambda function takes longer than 30 seconds to execute.
    
    If a fulfillment Lambda function returns a Delegate dialog action without removing any slot values.
    BadGatewayException - Either the Amazon Lex bot is still building, or one of the dependent services (Amazon Polly, AWS Lambda) failed with an internal service error.
    
    LoopDetectedException - This exception is not used.
    
    SdkException - Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
    
    SdkClientException - If any client side error occurs such as an IO related failure, failure to get credentials, etc.

Note that this is an unmanaged reference to the underlying HTTP connection so great care must be taken to ensure all data if fully read from the input stream and that it is properly closed. Failure to do so may result in sub-optimal behavior and exhausting connections in the connection pool. The unmarshalled response object can be obtained via ResponseInputStream.response(). The service documentation for the response content is as follows '
    The audio version of the message to convey to the user.
    '.
    
    Throws:
    
    NotFoundException - The resource (such as the Amazon Lex bot or an alias) that is referred to is not found.
    
    BadRequestException - Request validation failed, there is no usable message in the context, or the bot build failed, is still in progress, or contains unbuilt changes.
    
    LimitExceededException - Exceeded a limit.
    
    InternalFailureException - Internal service error. Retry the call.
    
    ConflictException - Two clients are using the same AWS account, Amazon Lex bot, and user ID.
    
    NotAcceptableException - The accept header in the request does not have a valid value.
    DependencyFailedException - One of the dependencies, such as AWS Lambda or Amazon Polly, threw an exception. For example,
    
    If Amazon Lex does not have sufficient permissions to call a Lambda function.
    
    If a Lambda function takes longer than 30 seconds to execute.
    
    If a fulfillment Lambda function returns a Delegate dialog action without removing any slot values.
    BadGatewayException - Either the Amazon Lex bot is still building, or one of the dependent services (Amazon Polly, AWS Lambda) failed with an internal service error.
    
    SdkException - Base class for all exceptions that can be thrown by the SDK (both service and client). Can be used for catch all scenarios.
    
    SdkClientException - If any client side error occurs such as an IO related failure, failure to get credentials, etc.
    
    LexRuntimeException - Base class for all service exceptions. Unknown exceptions will be thrown as an instance of this type.
