Mike,
from my viewpoint this sounds good as for now I don't need desktop speech
and would preferr console speech using the on-board audio out jack.
As a small project for anybody who wants both sources of speech to use the
same speakers/headphones, it's pretty easy to bung together a mixer that
goes between low level audi o out from two or more sources and amplified
(powered) speakers. A really good soldering practice project as it requires
no "board" and uses just jacks and pots.
Anybodyinterested ask and I'll put together a text discription of how to do
it.
Thanks for all your great work Mike and all.

Hello again.===========================================================
I have now tried using pulseaudio in the Mate desktop on the Pi and it
is very solid. It does not cause the same crash as we were seeing with
speech-dispatcher set up to use ALSA.
What is more is you don't get that nasty effect of the voice talking
over itself when you scroll rapidly down the menus.
But...
As I have explained elsewhere, when speech-dispatcher uses pulseaudio,
once you have logged in to the desktop, console speech stops because
espeak "sees" that pulse is running and tries to use it, but because
espeakup is running as root and pulseaudio is not, the result is a
silent console.
However, we have already solved this partly with my OMX audio code,
which we know does not stutter and does not use the ALSA driver, or
pulseaudio.
So, I can configure the Raspbian Mate image to:
1. Use a USB dongle and pulseaudio with speech-dispatcher in the desktop.
2. My OMX audio code in the console.
However, this does mean that console speech will come out of whatever
you have plugged in to either the analogue jack or the HDMI port while
desktop speech comes out of the USB dongle.
I think this is a small price to pay for what will be a very solid
speech experience in both.
What do people think?
Mike
