speakup & orca in debian 7

[Mike Ray]

Hello,

Espeakup doesn't use either portaudio or pulseaudio.  It just calls 
espeak, which in it's default configuration uses portaudio.

It is possible to re-compile espeak to use pulseaudio.  I have just done 
exactly that in efforts to get tts to work properly on Arch Linux on a 
Raspberry Pi.

espeak using portaudio suffers appalling latency on the Pi and sometimes 
crashes the kernel, but using pulseaudio the latency issues are gone.
