Pretty impressive from the limited look the website (https://cloud.google.com/speech/ https://cloud.google.com/speech/) gives: the fact that Google will clean the audio of background noise for you and supports streamed input is particularly interesting.

Would you need to alert users that Google will keep their recordings on file (probably indefinitely and without being able to delete them)?
