    # @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
    #     used to determine the service `:endpoint`. When not passed,

    #
    #     * `Aws.config[:region]`
    #     * `ENV['AWS_REGION']`
    #     * `ENV['AMAZON_REGION']`

    #   @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.

    # 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.

    #
    #   * Text format
    #

    #
    #     ^
    #
    # @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.
    #
    #   * If the value is `audio/pcm`, the speech returned is `audio/pcm` in
    #     16-bit, little endian format.
    #
    #   * The following are the accepted values:
    #
    #     * audio/mpeg
    #
    #     * audio/ogg
    #
    #     * audio/pcm

    #
    # @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.

    # Sends user input (text or SSML) to Amazon Lex. Client applications can
    # use this API to send requests to Amazon Lex at runtime. Amazon Lex
    # then interprets the user input using the machine learning model it
    # built for the bot.
    #
    # In response, Amazon Lex returns the next `message` to convey to the
    # user an optional `responseCard` to display. 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 obtain user
    #   confirmation "Proceed with the pizza order?".
    #
    # * After the user replies to a confirmation prompt with a "yes",
    #   Amazon Lex might return a conclusion statement: "Thank you, your
    #   cheese pizza has been ordered.".
    #
    # Not all Amazon Lex messages require a user response. For example, a
    # conclusion statement does not require a response. Some messages
    # require only a "yes" or "no" user response. In addition to the
    # `message`, Amazon Lex provides additional context about the message in
    # the response that you might use to enhance client behavior, for
    # example, to display the appropriate client user interface. These are
    # the `slotToElicit`, `dialogState`, `intentName`, and `slots` fields in
    # the response. Consider the following examples:
    #
    # * If the message is to elicit slot data, Amazon Lex returns the
    #   following context information:
    #
    #   * `dialogState` set to ElicitSlot
    #
    #   * `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][1].

    #
    # @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.
