How Can I Switch Synthesizers on the Fly?

How Can I Switch Synthesizers on the Fly?

[Chime Hart]

Hi All: I've asked others in other forums such as Slint-and-Debian 
Accessibility, but so far I am striking out. I have a DecTalk U S B, but last 
year I purchased some hi quality voices from Oralux, which are software speech. 
When I have Allison installed, I can send her text through spd-say. Making 
matters more complex, speech-dispatcher will not seem to install on this Debian 
Sid machine. Guidance I've received from 2 sources, says I must install and 
have espeak talking before I can switch to Allison, which is an embedded voice. 
When I was running Slint on a laptop, Didier had created a talk-with command to 
easily switch synths, but his script would need to be re written for Debian. In 
addition, 
if I unload the DecTalk module, I won't have speech, or would their be a way of 
having both DecTalk and software speech at the same time? So, can some1 please 
provide exact commands I can switch synths on the fly? I ran a locate for 
softsynth  but nothing found. Thanks so much in advance

I sure would like to get speakup using the Oralux Voxin Evan or Nathan as 
well
One suggestion I had was to install voxinup, but that may be an old 
unmaintained package.

I'm using raspberrypi's latest image on an RPI Zero.
I'm looking in:
/etc/speech-dispatcher/speechd.conf
and the default synth is
espeak-ng
Above that line, it says you must use one of the names added with AddModule.
I don't find any other names even though I ran the Voxin-installer.sh for 
Evan.
Seems like this is how to get it going.
spd-say still uses espeak for me.

This is contradictory. Having spd-say working implies a working and
installed speech-dispatcher. So, I will assume you have
speech-dispatcher installed and spd-say installed and working on one
machine, but not another. In that case saying speech-dispatcher won't
install doesn't help us help you.

If these voices interface through speech-dispatcher, then that would
make sense. However, the only way I know of to interface speakup to
speech-dispatcher right now is through speechd-up. So, it seems like
you would have to install speechd-up, get that working with
speech-dispatcher and espeak-ng, and once you have that working get
speech-dispatcher to use your purchased voices.

I can confirm the talkwith provided in the speakup-tools package for
debian bullseye seems to be broken. Issuing talkwith soft comes back
with:

/usr/sbin/talkwith: 88: shift: can't shift that many

I took a look at the script, but don't see where the problem is.

No, you can't have both your dectalk and software speech at the same time.

> So, can some1 please provide exact commands I can

No surprise. What you want is the speakup_soft module. You would as
root load that with:

modprobe speakup_soft

then start espeakup or speechd-up, depending on which one you use. I
think that would be something like:

systemctl speechd-up start
or
systemctl espeakup start

I'm not a systemd user, so someone else can correct the above if
they're not correct.

Now, assuming you have both speakup_soft and speakup_dectlk kernel
modules loaded, you can switch between them as root with:

echo dectlk >/sys/accessibility/speakup/synth

for the dectalk, and

echo soft >/sys/accessibility/speakup/synth

for software speech. Remember that before switching to dectlk you
should stop espeakup or speechd-up, and after switching to soft you
should start espeakup or speechd-up. I seem to recall you use csh, so
maybe someone can roll all that into a csh script for you.

Thank you Greg for your analysis. Yes I am in TCSH. When I run with

I get a permission error. As far as speechd-up  if I run an apt install in 
Debian, it tries installing a 0.5 version from 2011, but errors out. Here is an

I don't know how the echo in bash differs from the echo in tcsh if at
all. Did you modprobe the speakup_soft module?

You mentioned you had trouble installing speech-dispatcher. To work,
speechd-up requires an installed and configured speech-dispatcher. Do
you have speech-dispatcher installed and working with espeak-ng? If
you do, do you have a /var/log/speechd-up.log file? If yes, what does
it say?

Re: How Can I Switch Synthesizers on the Fly?

[Chime Hart]

Hi Greg: I did not run any modprobe commands today. I guess unless I needed to 
string 2 of them together to switch off the DecTalk-and-enable soft synth, 
because otherwise I might not have speech. I suppose I could use 2 separate 
consoles for both commands. Anyway, here are the contents of 
/var/log/speechd-up.log

It looks like modprobe speakup_soft would solve this.

Re: How Can I Switch Synthesizers on the Fly?

[Joseph C. Lininger]

I think your permission error might actually be a shell thing, not a 
speakup thing. Allow me to explain. I'm not trying to be condescending 
if you already understand the mechanics here, but I need to explain for 
my explanation of the problem to make sense.

When you type:

sudo echo soft >/sys/accessibility/speakup/synth

What you're doing is to run the command "sudo echo soft" as root, then 
telling your existing shell to redirect its output to the file 
/sys/accessibility/speakup/synth. Here in lies the problem; your 
existing (non-root) shell handles that file write operation. Only "echo 
soft" is actually run as root. The file 
/sys/accessibility/speakup/synth. can only be written by root, so you 
get a permission error. I tested this on my own system by creating a 
root-owned file, then trying "sudo echo test" and redirecting to that 
file. I got a permission error, as expected.

The only solution I know of is to create a shell script with the line

sudo echo soft >/sys/accessibility/speakup/synth

Then run that using sudo. That causes the write to take place as the 
root user, which is what you want.

Re: How Can I Switch Synthesizers on the Fly?

[Chime Hart]

Thank you Joe for a `wonderful explainer-and-I think you are most likely 
correct. We had similar results running an inflection script for the DecTalk.
Chime

Re: How Can I Switch Synthesizers on the Fly?

[Joseph C. Lininger]

My explanation of how to fix it was slightly incorrect actually. I told 
you to run sudo under sudo, basically, which is not necessary. I've 
provided what should be a full working script below. Try this script. It 
won't matter that you're running this under tcsh, as long as you have a 
working bash on your system. I've set it up to automatically execute bash.

-- begin script --
#!/bin/bash
# Force a couple of environment variables to sane values for security 
reasons
PATH=/bin:/usr/bin:/usr/local/bin:/sbin:/usr/sbin:/usr/local/sbin
IFS=" \t\n"
# Change the synth
echo "soft" > /sys/accessibility/speakup/synth
-- end script --

You could also add lines to the script to run whatever support programs 
you need to make the synthesizer work once you've switched it in 
Speakup. Don't add "sudo" to any lines in this script since it's already 
running as root. You'll run the script itself using sudo. For example, 
if you were to name the script enablesoft, and it were in your path, 
you'd type this.

sudo enablesoft

Assuming the rest of the parts are working, that should do it for you.

[-- Attachment #1: Type: text/plain, Size: 4315 bytes --]

Well Chime_and_all, let me chime in.

1. Slint doesn't ship the talkwith script, but a different one, named speak-with.

2. talkwith can be found in the archive provided here:
ftp://linux-speakup.org/pub/speakup/speakup-3.1.6.tar.bz2
in the tools directory

I ran talkwith here (in a yet to be released Slint64-15.0) and it still works.
I attach a copy of the script.

I having both espeakup and speechd-up installed, As in the kernel I run
currently has the speakup drivers provided as modules, I first typed as root:
mopdrobe speakup_soft # this also loads the speakup module as a dependency
then to start espeakup:
talkwith soft espeakup
then to start speechd-up
talkwith spd
then to start a my (non existing) Dec Talk:
modprobe speakup_dectlk
talkwith dectlk
All worked, but I can't check the last command as I do not owning such hardware.

So no need to fiddle manually with /sys if you use talkwith.

I can't help with installating speechd-up in Debian that I do not use.

PS I also typed:
tcsh talkwith soft espeakup
which displayed:
Illegal variable name
So Chime, I know that tcsh is the shell you are used to, but you certainly would
do us a favor typing your commands from another one before requesting help.

Here I use the bash shell, you could probably use ash or dash as well.

Cheers,
Didier
