Hello all,

Well, I am trying to get this synth to work.  I first downloaded the
PortAudio source but could not get it installed that way.  So I did a
check on slapt-get to see if there was a package for it....sure enough,
there was and I installed it.  Then, I had to create a symlink
libportaudio.so.0 to point to libportaudio.so.  There is another
portaudio file there, a .so file with a version string at the end so I
am not totally sure to which file I should be linking.  Then, I try
running the synth and get this error:
speak: symbol lookup error: speak: undefined symbol: Pa_StreamActive

Can anyone tell me what is up with this?

Thanks,
Robby

Firstly, it sounds like the portaudio package you installed is horribly 
broken, as the symbolic links should be created at package install time. 
As for where the symbolic links should point to, here is what I have on 
my system.

luke@linden:/usr/lib$ ls libportaudio.* -l
- -rw-r--r-- 1 root root 26844 2005-10-25 21:03 libportaudio.a
- -rw-r--r-- 1 root root   849 2005-10-25 21:03 libportaudio.la
lrwxrwxrwx 1 root root    22 2006-04-10 17:07 libportaudio.so -> 
libportaudio.so.0.0.18
lrwxrwxrwx 1 root root    22 2006-03-29 08:27 libportaudio.so.0 -> 
libportaudio.so.0.0.18
- -rw-r--r-- 1 root root 22764 2005-10-25 21:03 libportaudio.so.0.0.18

You can see that both symbolic links point to libportaudio.so.0.0.18. 
Just about all shared libraries installed on a Linux system have similar 
symbolic links, to allow program to be able to find libraries, even if 
libraries have received minor upgrades, say libportaudio.so.0.0.20. 
Thats how I understand it anyway.

As for the undefined symbol, I would strongly suggest you check what 
version of portaudio you have. I would also symbolically link as shown 
above, and re-compile the package just to be safe. I think version 18.1 
at least is required.

Hope this helps.

Re: Espeaks Software Synth

I guess that problem with the symbol lookup error is due to you using portaudio v19, you want v18 (uninstall v19). I probably can help with the compilation of portaudio as I have now managed on my desktop using slackware (I guess Robby is using slackware as slapt-get was mentioned). The solution, go to www.portaudio.com and download portaudio_v18.zip. unzip it somewhere (I did it in /usr/src/). Change to the portaudio directory (cd /usr/src/portaudio_v18/), and make a Makefile link to the Makefile.linux (ln ./Makefile.linux ./Makefile). Now just run "make" and "make libinstall". You now need to create the link for the lib (ln /usr/local/lib/libportaudio.so /usr/lib/libportaudio.so.0) assuming you didn't change the installation directory. Now espeak should run.

Well, if you are compiling from source not quite.  I have to admit I
cheated and installed the debian libportaudio-dev package which gave
me everything I needed from a portaudio perspective.  After compiling
you have to copy the espeak-data directory to /usr/share and then copy
the speak binary to /usr/bin.  There doesn't appear to be an
installation rule in the Makefile but that isn't really important.

It sounds quite good for a 350kb synth.  A British accent and a bit
heavy on the pitch shifting while reading but not unpleasant to
listen to in my opinion.  Of course, I am very forgiving when it comes
to synth voices so others may not find it as easy.

My congratulations to the authors of this bit of software.  It
definitely has potential.

I find Espeak quite easy to listen to when compared to Flite or
Festival.  And it's much smaller than either one.  The only problem I
have so far is that when you try to use it while playing a sound on a
single-channel sound card, it tends to lock so you have to manually kill
it before you can use it again.  But Espeak does seem to be in active
development, so maybe this can be fixed soon.  Otherwise, this is about
the best free open source synth I have heard.

Re: Espeaks Software Synth

I agree, espeak is good for what it is.
One should be able to get past the locking problem with other sound by 
making espeak produce a temporary .wav file and aplaying it through dmix.
This would require that the other application, the one producing the other 
sound, also can be convinsed to go through dmix.

Hello,

I have gotten the synthesizer to work; however, I am having problems
getting Speech-Dispatcher to find it.  I put the file that Lorenzo sent
me in /usr/local/etc/speech-dispatcher/modules as speak.conf (I am using
a packaged Speech-Dispatcher).  I then edited speechd.conf and added a
line like
AddModule "speak" "sd_speak" "speak.conf"
"/var/log/speech-dispatcher/speak.log"
Then I have a line like
DefaultModule speak
and then
LanguageDefaultModule "en"  "speak"

When I killall speech-dispatcher then run it again, it does not seem to
recognise the existence of this synth.  When I do spd-say -o speak
"hello" it speaks with Flite!  Also, it does not create a logfile for
speak such as I have set in that addmodule line above.  Any ideas?

Robby

There is no such module binary as sd_speak. The module you
want to use is sd_generic loaded with speak.conf
and thus named speak.

AddModule "speak" "sd_generic" "speak.conf"

You would find out Dispatcher is complaining about
non-existent sd_speak module if you looked into
the logfile in /var/log/speech-dispatcher/speechd.log .

Have a nice day.

Re: Espeaks Software Synth

[Willem van der Walt]

I think, without having checked, that the sd-speak should be sd-generic.
You are actually using the generic module of speech-dispatcher here.

Espeaks Software Synth

[Michael Whapples]

I think William's suggestion of getting espeak to produce a temporary wave 
file and getting another program to play that might give better results on 
some systems. On my laptop the conf file I posted earlier gives me no 
problems on my laptop (except that it uses oss instead of alsa), but on my 
desktop that conf file seems to not allow silencing (and when using my 
Terratec DMX6fire card (ICE1712 driver), I also get very poor response) but 
by making the change to have another app to play the sound these problems 
disappear on my desktop. Also I guess it would be possible to get it to use 
alsa with that output system. My only concern with that is, with large 
amounts of text, you may get poor response as espeak will have to process 
all the text before the wave file is ready (I don't know if 
speech-dispatcher seperates large text into smaller chunks).

also if you want to give espeak a different accent, you supposedly can, have 
a look at some of the docs about voices, dictionaries, etc, I think you are 
stuck with the voice itself though, as they haven't released the voice 
creation tools. There has been a little mention about it on the espeak 
forum.

Speech-dispatcher can cut up the text that goes to the synth.  I have 
actually done what i have suggested with another software synth and had no 
problems.  The idea of using the aplayer program is that one can then use 
alsa.

Robby,
If you are using a packaged version of speech-dispatcher (you did not 
compile it from source) the modules directory might be in a different place 
(on my laptop using gentoo it is /etc/speech-dispatcher/modules), if the 
directory was already there, then it is probably that directory, just check 
it (you might have been correct).

The line you added to speechd.conf to add the module is wrong, it uses the 
generic module, so you would need the following for your setup.
AddModule "speak" "sd_generic" "speak.conf" 
"/var/log/speech-dispatcher/speak.log"
This should now make it work.
