If you do chase down what it does that is causing Emacspeak to break -- I'd like to know -- most likely it's latching something on to post-self-insert-hook that is then conflicting with Emacspeak's own entry on that hook for speaking characters as you type. > Hi Raman, > > sorry, I wasn't clear enough. > > When the bug is triggered, emacspeak will continue to speak, but most emacs commands have no effect.

Depending on your system, load etc, you may also here "Back to top level".

Took a bit for me to track this down. However, combining this issue with emacspeak-play-auditory-icons meant that the impact from the error was much worse and made my system even > less usable than it would be for someone encountering this bug without this package. > > This also highlights another gotcha emacspeak users need to be aware of. As we all know, sometimes new packages are not as emacspeak friendly as we might like and can change things such that we may not get adequate > spoken feedback in some circumstances. In the past, this wasn't too bad as we installed new code by hand and knew exactly what had been installed.

It is just a point of warning that if you install a new package and it causes unwanted side effect which impact on emacspeak, you probably want to check exactly what packages it installs. . > > On 22 August 2015 at 23:56, T.
