     This function requires a Google Cloud Platform account; see the `Set up Speech-to-Text <https://cloud.google.com/speech-to-text/docs/before-you-begin>`__ for details and instructions. Basically, create a project, enable billing for the project, enable the Google Cloud Speech API for the project.
