    # @overload initialize(options)
    #   @param [Hash] options
    #   @option options [required, Aws::CredentialProvider] :credentials
    #     Your AWS credentials. This can be an instance of any one of the
    #     following classes:
    #
    #     * `Aws::Credentials` - Used for configuring static, non-refreshing
    #       credentials.
    #
    #     * `Aws::InstanceProfileCredentials` - Used for loading credentials
    #       from an EC2 IMDS on an EC2 instance.
    #
    #     * `Aws::SharedCredentials` - Used for loading credentials from a
    #       shared file, such as `~/.aws/config`.
    #
    #     * `Aws::AssumeRoleCredentials` - Used when you need to assume a role.
    #
    #     When `:credentials` are not configured directly, the following
    #     locations will be searched for credentials:
    #
    #     * `Aws.config[:credentials]`
    #     * The `:access_key_id`, `:secret_access_key`, and `:session_token` options.
    #     * ENV['AWS_ACCESS_KEY_ID'], ENV['AWS_SECRET_ACCESS_KEY']
    #     * `~/.aws/credentials`
    #     * `~/.aws/config`
    #     * EC2 IMDS instance profile - When used by default, the timeouts are
    #       very aggressive. Construct and pass an instance of
    #       `Aws::InstanceProfileCredentails` to enable retries and extended
    #       timeouts.
    #
    #   @option options [required, String] :region
    #     The AWS region to connect to.  The configured `:region` is

    #
    #   @option options [String] :endpoint
    #     The client endpoint is normally constructed from the `:region`
    #     option. You should only configure an `:endpoint` when connecting
    #     to test endpoints. This should be avalid HTTP(S) URI.
    #
    #   @option options [Integer] :endpoint_cache_max_entries (1000)
    #     Used for the maximum size limit of the LRU cache storing endpoints data

    #     is not set, logging will be disabled.
    #
    #   @option options [String] :profile ("default")
    #     Used when loading credentials from the shared credentials file
    #     at HOME/.aws/credentials.  When not specified, 'default' is used.
    #
    #   @option options [Float] :retry_base_delay (0.3)
    #     The base delay in seconds used by the default backoff function.
    #
    #   @option options [Symbol] :retry_jitter (:none)
    #     A delay randomiser function used by the default backoff function. Some predefined functions can be referenced by name - :none, :equal, :full, otherwise a Proc that takes and returns a number.
    #
    #     @see https://www.awsarchitectureblog.com/2015/03/backoff.html
    #
    #   @option options [Integer] :retry_limit (3)
    #     The maximum number of times to retry failed requests.  Only
    #     ~ 500 level server errors and certain ~ 400 level client errors
    #     are retried.  Generally, these are throttling errors, data
    #     checksum errors, networking errors, timeout errors and auth
    #     errors from expired credentials.
    #
    #   @option options [Integer] :retry_max_delay (0)
    #     The maximum number of seconds to delay between retries (0 for no limit) used by the default backoff function.
    #
    #   @option options [String] :secret_access_key
    #
    #   @option options [String] :session_token
    #
    #   @option options [Boolean] :stub_responses (false)
    #     Causes the client to return stubbed responses. By default
    #     fake responses are generated and returned. You can specify
    #     the response data to return or errors to raise by calling
    #     {ClientStubs#stub_responses}. See {ClientStubs} for more information.
    #
    #     ** Please note ** When response stubbing is enabled, no HTTP
    #     requests are made, and retries are disabled.
    #
    #   @option options [Boolean] :validate_params (true)
    #     When `true`, request parameters are validated before
    #     sending the request.

    # @!group API Operations

    # 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][1].

    #
    # @option params [required, String] :bot_name
    #   Name of the Amazon Lex bot.
    #
    # @option params [required, String] :bot_alias
    #   Alias of the Amazon Lex bot.
    #
    # @option params [required, String] :user_id
    #   The ID of the client application user. Amazon Lex uses this to
    #   identify a user's conversation with your bot. At runtime, each
    #   request must contain the `userID` field.
    #
    #   To decide the user ID to use for your application, consider the
    #   following factors.
    #
    #   * The `userID` field must not contain any personally identifiable
    #     information of the user, for example, name, personal identification
    #     numbers, or other end user personal information.
    #
    #   * If you want a user to start a conversation on one device and
    #     continue on another device, use a user-specific identifier.
    #
    #   * If you want the same user to be able to have two independent
    #     conversations on two different devices, choose a device-specific
    #     identifier.
    #
    #   * A user can't have two independent conversations with two different
    #     versions of the same bot. For example, a user can't have a
    #     conversation with the PROD and BETA versions of the same bot. If you
    #     anticipate that a user will need to have conversation with two
    #     different versions, for example, while testing, include the bot
    #     alias in the user ID to separate the two conversations.
    #
    # @option params [String] :session_attributes
    #   You pass this value as the `x-amz-lex-session-attributes` HTTP header.
    #
    #   Application-specific information passed between Amazon Lex and a
    #   client application. The value must be a JSON serialized and base64
    #   encoded map with string keys and values. The total size of the
    #   `sessionAttributes` and `requestAttributes` headers is limited to 12
    #   KB.
    #
    #   For more information, see [Setting Session Attributes][1].
    #
    #   **SDK automatically handles json encoding and base64 encoding for you
    #   when the required value (Hash, Array, etc.) is provided according to

    #   [1]: http://docs.aws.amazon.com/lex/latest/dg/context-mgmt.html#context-mgmt-session-attribs
    #
    # @option params [String] :request_attributes
    #   You pass this value as the `x-amz-lex-request-attributes` HTTP header.
    #
    #   Request-specific information passed between Amazon Lex and a client
    #   application. The value must be a JSON serialized and base64 encoded
    #   map with string keys and values. The total size of the

    #
    # @option params [required, String] :content_type
    #   You pass this value as the `Content-Type` HTTP header.
    #
    #   Indicates the audio format or text. The header value must start with
    #   one of the following prefixes:
    #
    #   * PCM format, audio data must be in little-endian byte order.
    #
    #     * audio/l16; rate=16000; channels=1
    #
    #     * audio/x-l16; sample-rate=16000; channel-count=1
    #
    #     * audio/lpcm; sample-rate=8000; sample-size-bits=16;
    #       channel-count=1; is-big-endian=false
    #
    #   * Opus format
    #
    #     * audio/x-cbr-opus-with-preamble; preamble-size=0; bit-rate=256000;
    #       frame-size-milliseconds=4
    #
    #     ^
    #
    #   * Text format
    #
    #     * text/plain; charset=utf-8
    #
    #     ^
    #
    # @option params [String] :accept
    #   You pass this value as the `Accept` HTTP header.
    #
    #   The message Amazon Lex returns in the response can be either text or
    #   speech based on the `Accept` HTTP header value in the request.
    #
    #   * If the value is `text/plain; charset=utf-8`, Amazon Lex returns text
    #     in the response.
    #
    #   * If the value begins with `audio/`, Amazon Lex returns speech in the
    #     response. Amazon Lex uses Amazon Polly to generate the speech (using
    #     the configuration you specified in the `Accept` header). For
    #     example, if you specify `audio/mpeg` as the value, Amazon Lex
    #     returns speech in the MPEG format.
    #
    #     The following are the accepted values:
    #
    #     * audio/mpeg
    #
    #     * audio/ogg
    #
    #     * audio/pcm
    #
    #     * text/plain; charset=utf-8
    #
    #     * audio/* (defaults to mpeg)
    #
    # @option params [required, String, IO] :input_stream
    #   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.
    #
    # @return [Types::PostContentResponse] Returns a {Seahorse::Client::Response response} object which responds to the following methods:

    #   * `dialogState` set to ElicitSlot
    #
    #   * `intentName` set to the intent name in the current context

    #     currently known values
    #
    # * If the message is a confirmation prompt, the `dialogState` is set to
    #   ConfirmIntent and `SlotToElicit` is set to null.
    #

    # @option params [required, String] :bot_name
    #   The name of the Amazon Lex bot.
    #
    # @option params [required, String] :bot_alias
    #   The alias of the Amazon Lex bot.
    #
    # @option params [required, String] :user_id
    #   The ID of the client application user. Amazon Lex uses this to
    #   identify a user's conversation with your bot. At runtime, each
    #   request must contain the `userID` field.
    #
    #   To decide the user ID to use for your application, consider the
    #   following factors.
    #
    #   * The `userID` field must not contain any personally identifiable
    #     information of the user, for example, name, personal identification
    #     numbers, or other end user personal information.
    #
    #   * If you want a user to start a conversation on one device and
    #     continue on another device, use a user-specific identifier.
    #
    #   * If you want the same user to be able to have two independent
    #     conversations on two different devices, choose a device-specific
    #     identifier.
    #
    #   * A user can't have two independent conversations with two different
    #     versions of the same bot. For example, a user can't have a
    #     conversation with the PROD and BETA versions of the same bot. If you
    #     anticipate that a user will need to have conversation with two
    #     different versions, for example, while testing, include the bot
    #     alias in the user ID to separate the two conversations.
