Term Help And Recovery (Emacsvox User Manual)

If terminal output is visible but silent, press C-t C-q once and retry. Automatic speech applies only while the Term buffer is displayed.
If an Emacs command is being sent to the child program, remember that you are probably in character mode. Use C-c C-h m, C-c M-x, or switch to line mode with C-c C-j.
If review has drifted away from live output, press C-t .. If dedicated review mode controls the keys, press q first to return to character mode.
If a full-screen application redraws in a way that Term cannot present reliably, retry it in Speech Access To EAT and use EAT’s explicit review commands.
