Prerequisites

The user is responsible for providing a working Python environment for this application. If you need help with this step, see the PythonWiki beginner's guide.

Additionally, this application relies on ffmpeg (specifically, ffplay) to play audio at the command line. The user is responsible for ensuring this utility is installed and on the PATH.

Unfortunately, google-cloud is a developer-oriented experience, so the following steps are pretty technical.

• Set up a google cloud account.
• Activate the speech and cloud storage APIs.
• Create a cloud storage bucket named voice-recognition-staging.
  • Highly recommended: Set a lifecycle management policy to delete objects in this bucket after 1 day.
• Set up credentials on your system.

Installing

At the command line, type pip install autocaption.
