See Contexts for details.
The transcription text that shows on the top of the page when you speak and LipSurf is activated. Can be configured in the options.

Will be changed to "headphones mode" soon. When you don't use headphones, audio from the speakers can feed back into the microphone which is usually undesirable when you're watching a video. With "no headphones mode" on the live transcript does not show when media is detected to be playing on the page — unless there's a valid command.
All the commands in LipSurf are grouped into families called plugins. LipSurf plugins can be created by anyone. They extend the default functionality of LipSurf to make it infinitely extensible.
