The problem isn't adding an option, it is getting rid of one. 

I have emacspeak-play-args set to nil, but still get -N passed as an
argument. This is why I use the shell scirpt. using paplay, no
arguments are required. The shell script simply pulls out the second
argument (the name of the sound file) and passes it to paplay.

+1 for pulseaudio.  I think its unfairly maligned. I find it stable
and useful.  I like playing music on speakers and listening to TTS
onUSB headphones, and being able to easily move between them.

Re: Emacspeak with eSpeak losing speech on Vinux 4

per-application volume control is one of its unique features.

According to what I've read on LWN and elsewhere, most of the problems that
people have experienced are attributable to issues in audio drivers that
PulseAudio exposes, rather than to problems with PulseAudio itself.

The simplification of real-time scheduling priority should help too.

This is a sufficiently common configuration that I think it ought to be made
to work, and I'll play my part with bug reports.

While I seem to be the exception, I find pulseaudio to be really good.
I've not observed the latency issues reported by others and really
like the simplicity of being able to set different volume levels for
different devices. I enjoy being able to now have TTS at the same time
as playing some background music or half listening to a podcast etc. I
also enjoy not having to tweak an .asoundrc file on every system I use
just to get the sound quality out of viavoice to be OK.

Re: Emacspeak with eSpeak losing speech on Vinux 4

Jason White — 2013-05-14T02:35:24

 

I think that will be due to the packaging bug I just fixed in Debian. I would
expect the bug fix to find its way to the corresponding Ubuntu package as
well.

I'm using a USB headset, which identifies itself as a standard USB audio
device. HOwever, I'm running PulseAudio 2.0, not the latest version, which is
now 3.0. Whenever I can upgrade without breaking lots of dependencies (as is
currently an issue with the state of Debian shortly after a release, with lots
of new packages being uploaded), I'll test again.

To be clear, I don't need PulseAudio as such; this is basically an effort to
help the community a little with an increasingly common configuration that
will be with us for a long time. An article on LWN a while ago indicated that
the PulseAudio developers are keen to resolve remaining issues, and it also
appears that Luke Yelavich, known for his accessibility work in Ubuntu and
elsewhere, is a PulseAudio developer too.

Emacspeak And Speech-dispatcher

Tim Cross — 2013-05-14T02:34:02


I have thought about it, but not done anything. It would be quite
possible, though you may lose some functionality due to the need to
map between emacspeak speech commands and those supported by
speech-dispatcher.

You can run speech-dispatcher system wide by changing some configs in
the spd.conf file.

I has this when I first started using emacspeak about a year ago, with
Ubuntu 11.10, stock everything. Speech  stuttered whenever any key was
struck, to the point it was unusable.  The only fix was to use Voxin +
Outloud.

You will need a simple shell script as there is an additional argument
passed which is not controlled by customise. I use the following 

#!/bin/bash

#echo $* >> /home/tcross/play-args
#echo $1 >> /home/tcross/play-args
#echo $2 >> /home/tcross/play-args

paplay $2 &

I have this in ~/bin/play and set emacspeak-play-program to it.
emacspeak-play-args is empty i.e. "".

I'm running espeak 1.47.05, which I built from source and which is
configured to use pulseaudio. The distro supplied versions of espeak
have never worked well for me. I always have to recompile and set to
use pulseaudio before espeak works well and does not chop off words
and crash every few lines. 

I'm running a totally default pulseaudio setup on both my systems (one
Linux Mint 14 and one Ubuntu 13.04). 

Both systems are using integrated intel audio cards. However, on a
previous system, using an Sound Blaster card (can't remember what it
was, but it had an unusually high input sample rate), I did have to
tweak the pulseaudio configuration to get reliable audio. In
particular, I had to set sample rate and some other settings. I worked
out what was needed by increasing the log level for pulseaudio and a
long test, tweak, restart, test cycle. However, this was quite a while
back with considerably older versions of pulseaudio and when there was
still some flux in how linux was dealing wiht real time schedul

The problem turned out to be an error in the Debian packaging that probably
also affects Ubuntu users. I've submitted a patch.

This doesn't solve my Emacspeak speech server/Espeak problems - in fact, it
makes them worse: I now get very broken up audio as soon as I interrupt speech
for any reason. Has anyone else seen this when using PulseAudio for output?
Any suggestions?

On the positive side, if we can call it that, I haven't lost speech entirely
during the few minutes that I've tested with PulseAudio properly enabled.

We aren't out of the woods but I hope we're starting to get a map of the
terrain.

HADEN,

I don't see why it would not be possible.  It may not be possible to get
a totally full featured speech server but certainly a working one should
be achievable.

I am not aware that anyone is currently working on this but I may be
wrong.

Is someone working on implementing a Speech-dispatcher server?  Is it

Re: Emacspeak with eSpeak losing speech on Vinux 4

Jason White — 2013-05-13T05:48:20

 


After building with AUDIO=runtime, the version of wave_init() which is called
is the one in src/wave.cpp:759 that invokes PortAudio, not the wrapper
function earlier in the file that checks for PulseAudio. Thus we end up
writing to Alsa directly, which as I mentioned may indirectly invoke Pulse.

I haven't spent time trying to sort this out, since there are quite a few
#ifdef and #define directives involved and therefore not obvious which code
will be compiled with each combination of compile-time options.

Re: Emacspeak with eSpeak losing speech on Vinux 4

Christopher Chaltain — 2013-05-13T05:28:09

Interesting. I definitely get a different behavior when I recompile 
eSpeak myself using the runtime compile option. I don't get the chopping 
off of the last syllable that I get when I use the default PortAudio 
setting.

Thanks Jason and all for looking into this issue and the various 
suggestions I still need to work through myself.
