Jonathan, I didn't have a problem with speech-dispatcher either.
Getting a desktop to speak is easy. But unless you have stable console speech, imho it is not an accessible Pi. The problem with console speech is that using either alsa, or any other sound library that goes via the Broadcom sound driver, tts stutters very badly and about every thirty seconds causes a kernel oops. The kernel oops is caused by the Video Core Hardware Interface Queue (VCHIQ) sending the kernel a null pointer. I'm coding to solve this issue by use of the OpenMax integration layer to render audio directly on the GPU, so bypassing the snd-bcm2835 driver. In order to have this working for speakup, emacspeak and speech-dispatcher I am writing new code for espeak, which will fix speakup and emacspeak, and a new module for speech-dispatcher which will stop sd crashing the kernel.
