Chime on door opening

 I have an Amazon Fire 8 and installed LANnouncer to create a chime when a particular door opens but although the sound on the tablet is set at the max, the chime is pretty faint. So I added BigTalker to ST, per the Konnected instructions ( and I don't see any option to create a chime under "what to say". (in fact, my PC cannot even find "what to say." Has anyone managed to successfully set up a chime on Fire HD and if so, how? Thanks in advance.
