Deprecated since version 0.0.32: Use langchain_google_community.SpeechToTextLoader instead.

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
