.. py:class:: GcpTranslateSpeechOperator(audio, config, target_language, format_, source_language, model, project_id=None, gcp_conn_id='google_cloud_default', *args, **kwargs)

   Bases: :class:`airflow.models.BaseOperator`

   Recognizes speech in audio input and translates it.

   Note that it uses the first result from the recognition api response - the one with the highest confidence
   In order to see other possible results please use
   :ref:`howto/operator:GcpSpeechToTextRecognizeSpeechOperator`
   and
   :ref:`howto/operator:CloudTranslateTextOperator`
   separately

   See https://cloud.google.com/translate/docs/translating-text

   Execute method returns string object with the translation

   This is a list of dictionaries queried value.
   Dictionary typically contains three keys (though not
   all will be present in all cases).

   * ``detectedSourceLanguage``: The detected language (as an
     ISO 639-1 language code) of the text.
   * ``translatedText``: The translation of the text into the
     target language.
   * ``input``: The corresponding input value.
   * ``model``: The model used to translate the text.

   Dictionary is set as XCom return value.

   :param audio: audio data to be recognized. See more:
       https://googleapis.github.io/google-cloud-python/latest/speech/gapic/v1/types.html#google.cloud.speech_v1.types.RecognitionAudio
   :type audio: dict or google.cloud.speech_v1.types.RecognitionAudio

   :param config: information to the recognizer that specifies how to process the request. See more:
       https://googleapis.github.io/google-cloud-python/latest/speech/gapic/v1/types.html#google.cloud.speech_v1.types.RecognitionConfig
   :type config: dict or google.cloud.speech_v1.types.RecognitionConfig

   :param target_language: The language to translate results into. This is required by the API and defaults
       to the target language of the current instance.
       Check the list of available languages here: https://cloud.google.com/translate/docs/languages
   :type target_language: str

   :param format_: (Optional) One of ``text`` or ``html``, to specify
       if the input text is plain text or HTML.
   :type format_: str or None

   :param source_language: (Optional) The language of the text to
       be translated.
   :type source_language: str or None

   :param model: (Optional) The model used to translate the text, such
       as ``'base'`` or ``'nmt'``.
   :type model: str or None

   :param project_id: Optional, Google Cloud Platform Project ID where the Compute
       Engine Instance exists.  If set to None or missing, the default project_id from the GCP connection is
       used.
   :type project_id: str

   :param gcp_conn_id: Optional, The connection ID used to connect to Google Cloud
       Platform. Defaults to 'google_cloud_default'.
   :type gcp_conn_id: str
