class langchain_google_community.google_speech_to_text.SpeechToTextLoader(project_id: str, file_path: str, location: str = 'us-central1', recognizer_id: str = '_', config: RecognitionConfig | None = None, config_mask: FieldMask | None = None, is_long: bool = False)[source]#

Loader for Google Cloud Speech-to-Text audio transcripts.

It uses the Google Cloud Speech-to-Text API to transcribe audio files and loads the transcribed text into one or more Documents, depending on the specified format.

To use, you should have the google-cloud-speech python package installed.

Audio files can be specified via a Google Cloud Storage uri or a local file path.

For a detailed explanation of Google Cloud Speech-to-Text, refer to the product documentation. https://cloud.google.com/speech-to-text

Initializes the GoogleSpeechToTextLoader.

Parameters:

project_id (str) – Google Cloud Project ID.
file_path (str) – A Google Cloud Storage URI or a local file path.
location (str) – Speech-to-Text recognizer location.
recognizer_id (str) – Speech-to-Text recognizer id.
config (Optional[RecognitionConfig]) – Recognition options and features. For more information: https://cloud.google.com/python/docs/reference/speech/latest/google.cloud.speech_v2.types.RecognitionConfig
config_mask (Optional[FieldMask]) – The list of fields in config that override the values in the default_recognition_config of the recognizer during this recognition request. For more information: https://cloud.google.com/python/docs/reference/speech/latest/google.cloud.speech_v2.types.RecognizeRequest
is_long (bool) – use async Cloud Speech recognition, mainly for long documents For more information: https://cloud.google.com/speech-to-text/v2/docs/batch-recognize
