Your department provides audio transcription services for other departments in your company. Users upload audio files to a Cloud Storage bucket. Your application transcribes the audio and writes the transcript file back to the same bucket. Your process runs every day at midnight and transcribes all files in the bucket. Users are complaining that they are not notified if there is a problem with the audio file format until the next day. Your application has a program that can verify the quality of an audio file in less than two seconds. What changes would you make to the workflow to improve user satisfaction?
