By default, Emacspeak speaks characters as they are typed — this is called character echo; Words are spoken as they are completed — this is called word echo. Emacspeak can also optionally speak each line as it is typed — this is called line echo.
Character, word and line echo can be toggled — either in the current buffer — or for all buffers (globally). To toggle the specific echo functionality for all buffers, precede the specific command with C-u. Note that in the documentation below, this use of C-u is indicated using the common Emacs terminology of prefix arg or interactive prefix arg.
emacspeak-toggle-character-echo

emacspeak-toggle-word-echo

emacspeak-toggle-line-echo
