<div class="method">

<pre>Performs asynchronous speech recognition: receive results via the
google.longrunning.Operations interface. Returns either an
`Operation.error` or an `Operation.response` which contains
a `LongRunningRecognizeResponse` message.
Args:
body: object, The request body. (required)
The object takes the form of:
{ # The top-level message sent by the client for the `LongRunningRecognize`
# method.
"audio": { # Contains audio data in the encoding specified in the `RecognitionConfig`. # *Required* The audio data to be recognized.
# Either `content` or `uri` must be supplied. Supplying both or neither
# returns google.rpc.Code.INVALID_ARGUMENT. See
# [audio limits](https://cloud.google.com/speech/limits#content).
"content": "A String", # The audio data bytes encoded as specified in
# `RecognitionConfig`. Note: as with all bytes fields, protobuffers use a
# pure binary representation, whereas JSON representations use base64.
"uri": "A String", # URI that points to a file that contains audio data bytes as specified in
# `RecognitionConfig`. Currently, only Google Cloud Storage URIs are
# supported, which must be specified in the following format:
# `gs://bucket_name/object_name` (other URI formats return
# google.rpc.Code.INVALID_ARGUMENT). For more information, see
# [Request URIs](https://cloud.google.com/storage/docs/reference-uris).
},

# request.
"languageCode": "A String", # *Required* The language of the supplied audio as a
# [BCP-47](https://www.rfc-editor.org/rfc/bcp/bcp47.txt) language tag.
# Example: "en-US".
# See [Language Support](https://cloud.google.com/speech/docs/languages)
# for a list of the currently supported language codes.
"encoding": "A String", # *Required* Encoding of audio data sent in all `RecognitionAudio` messages.
"maxAlternatives": 42, # *Optional* Maximum number of recognition hypotheses to be returned.
# Specifically, the maximum number of `SpeechRecognitionAlternative` messages
# within each `SpeechRecognitionResult`.
# The server may return fewer than `max_alternatives`.
# Valid values are `0`-`30`. A value of `0` or `1` will return a maximum of
# one. If omitted, will return a maximum of one.
"sampleRateHertz": 42, # *Required* Sample rate in Hertz of the audio data sent in all
# `RecognitionAudio` messages. Valid values are: 8000-48000.
# 16000 is optimal. For best results, set the sampling rate of the audio
# source to 16000 Hz. If that's not possible, use the native sample rate of
# the audio source (instead of re-sampling).
"profanityFilter": True or False, # *Optional* If set to `true`, the server will attempt to filter out
# profanities, replacing all but the initial character in each filtered word
# with asterisks, e.g. "f***". If set to `false` or omitted, profanities
# won't be filtered out.
"speechContexts": [ # *Optional* A means to provide context to assist the speech recognition.
{ # Provides "hints" to the speech recognizer to favor specific words and phrases
# in the results.
"phrases": [ # *Optional* A list of strings containing words and phrases "hints" so that
# the speech recognition is more likely to recognize them. This can be used
# to improve the accuracy for specific words and phrases, for example, if
# specific commands are typically spoken by the user. This can also be used
# to add additional words to the vocabulary of the recognizer. See
# [usage limits](https://cloud.google.com/speech/limits#content).

Returns:
An object of the form:
{ # This resource represents a long-running operation that is the result of a
# network API call.
"metadata": { # Service-specific metadata associated with the operation. It typically

# If true, the operation is completed, and either `error` or `response` is
# available.
"response": { # The normal response of the operation in case of success. If the original
# method returns no data on success, such as `Delete`, the response is
# `google.protobuf.Empty`. If the original method is standard
# `Get`/`Create`/`Update`, the response should be the resource. For other
# methods, the response should have the type `XxxResponse`, where `Xxx`

# is `TakeSnapshot()`, the inferred response type is
# `TakeSnapshotResponse`.

# originally returns it. If you use the default HTTP mapping, the

# programming environments, including REST APIs and RPC APIs. It is used by
# [gRPC](https://github.com/grpc). The error model is designed to be:
#
# - Simple to use and understand for most users
# - Flexible enough to meet unexpected needs
#
# # Overview
#
# The `Status` message contains three pieces of data: error code, error message,
# and error details. The error code should be an enum value of
# google.rpc.Code, but it may accept additional error codes if needed. The
# error message should be a developer-facing English message that helps
# developers *understand* and *resolve* the error. If a localized user-facing
# error message is needed, put the localized message in the error details or
# localize it in the client. The optional error details may contain arbitrary
# information about the error. There is a predefined set of error detail types
# in the package `google.rpc` that can be used for common error conditions.
#
# # Language mapping
#
# The `Status` message is the logical representation of the error model, but it
# is not necessarily the actual wire format. When the `Status` message is
# exposed in different client libraries and different wire protocols, it can be
# mapped differently. For example, it will likely be mapped to some exceptions
# in Java, but more likely mapped to some error codes in C.
#
# # Other uses
#
# The error model and the `Status` message can be used in a variety of
# environments, either with or without APIs, to provide a
# consistent developer experience across different environments.
#
# Example uses of this error model include:
#
# - Partial errors. If a service needs to return partial errors to the client,
# it may embed the `Status` in the normal response to indicate the partial
# errors.
#
# - Workflow errors. A typical workflow has multiple steps. Each step may
# have a `Status` message for error reporting.
#
# - Batch operations. If a client uses batch request and batch response, the
# `Status` message should be used directly inside batch response, one for
# each error sub-response.
#
# - Asynchronous operations. If an API call embeds asynchronous operation
# results in its response, the status of those operations should be
# represented directly using the `Status` message.
#
# - Logging. If some API errors are stored in logs, the message `Status` could
# be used directly after any stripping needed for security/privacy reasons.
"message": "A String", # A developer-facing error message, which should be in English. Any
# user-facing error message should be localized and sent in the
# google.rpc.Status.details field, or localized by the client.
"code": 42, # The status code, which should be an enum value of google.rpc.Code.
"details": [ # A list of messages that carry the error details. There will be a
# common set of message types for APIs to use.
