speech-dispatcher makes pulseaudio eat cpu time

[Jean-Noël AVILA]

Dear Maintainer,

I just tried to have tts on my system and I noticed that if I use spd-say to 
use TTS with output as pulseaudio, after the end of the sentence, pulseaudio 
keeps waking up and sending some data regularly. I have to kill speech-
dispatcher to settle pulse-audio down again.

Otherwise, stracing pulseaudio shows the following:
 sudo strace -r -p 3720
Process 3720 attached - interrupt to quit
