  In fact it would probably be good to develop a
  speech-dispatcher version that can be compiled and run on
  android.

  Anyway I am certainly not in this mind for at least two
  reasons : First I do not have any system with android
  installed so no opportunity to make tests. Secondly I no
  longer use speech-dispatcher.

  In fact I developped a direct client from speechd-el to
  festival. Since festival do not have the scheduling features
  implemented by speech-dispatcher I had to implement a
  scheduler for festival what I did.

  I is certainly possible but I never use espeak so do not
  really know what are its features. In particular is it easy
  to interrupt a speaking message with espeak, is it possible
  to queue the messages with given priorities. All such
  features are needed to implement the ssip protocol. That
  precisely the part that was badly supported by festival.
