Re: Severe issue installing emacspeak for Ubuntu users



The process speaker not running error usually means you have not got the text-to-speech synth layer installed/setup correctly or you have not told emacspeak which tts synth interface to use. There are clear instructions within the Makefile which tell you how to test the various components individually. You need to do this to work out where the error runs. 

Just for the record, I run emacspeak on Ubuntu 13.04, Kali Linux (Debian based), Linux Mint and Fedora with no issues (mainly 64 bit). Problems are almost always configuration/setup issues. Don't forget that you need to set some environment variables to tell emacspeak which tts synth you are using and remember that it is possible that once you have set these (usually in your .profile), you either need to source the updated .profiel to ensure those changes are added to your current shell (not forgetting that this will only set the required variables in the current session - people get confused about different console sessions or terminals, espeailly when running under X). Sometimes, just to simplify matters, I recommend after updating your .profile to reboot your system - this at least will ensure consistency. Above all, read and follow the recommendations in the Makefile and varify all your components are working correctly. If you still have problems, at least you will know exactly where they problems are and we will be able to provide more accurate assistance.

*** Installing Emacs 24

$ sudo apt-get install emacs24

If you want to install Emacs snapshots, which come out every couple of days, I came across the following. I didn't have any trouble with the snapshots, but I don't need to be on the bleeding edge when it comes to Emacs, and my apt-get upgrade runs more quickly if I just stick with Emacs24.

I got the following instructions from http://sinewalker.wordpress.com/2012/02/13/install-emacs24-snapshot-on-debian-ubuntu-and-windows-7/

Ubuntu

I’m running Ubuntu 11.10 in a VirtualBox on work’s Windows 7 machine. As mentioned at Julien Danjou’s page,
Damien Cassou makes a version of the same emacs-snapshot for Ubuntu, which is hosted at Launchpad. You add it and install simalarly:

Add the PPA (Personal Package Archive). This also imports the key:

$ sudo add-apt-repository ppa:cassou/emacs

Update your package database

$ sudo apt-get update

Install emacs-snapshot

$ sudo apt-get install emacs-snapshot

*** Installing Emacspeak

**** Getting and Making Emacspeak

I downloaded the latest Emacspeak, emacspeak-37.0.tar.bz2, from http://code.google.com/p/emacspeak/.

fter unpacking this file, I went into the resulting directory, i.e. emacspeak-37.0, and ran the following commands:

$ make config
$ make emacspeak

$ sudo apt-get install texinfo

$ sudo make install

Note that in the future I want to change the prefix to /usr/local before making Emacspeak, at least until I figure out how to package it.

I also went into /usr/bin/emacspeak and changed the last line to be:

exec emacs -l /usr/share/emacs/site-lisp/emacspeak/lisp/emacspeak-setup.el $INITSTR $CL_ALL

**** Making the eSpeak Server

I installed the following dependencies:

$ sudo apt-get install tcl8.4 tclx8.4 tk8.4 tcl8.4-dev libasound2-dev

I got this list from the Voxin scripts, but I need to double chek it.

I also needed to install the following development package:

$ sudo apt-get install libespeak-dev

I went into /usr/share/emacs/site-lisp/emacspeak/servers/linux-espeak and ran:

$ sudo make all

In the servers directory, I ran

$ ./espeak

to make sure the server was working.

Now

$ emacspeak -e

came up with emacspeak talking and using eSpeak.

**** Recompiling eSpeak to Use PulseAudio

Unfortunately, the last syllable spoken is always truncated making it unusable.

(Note to bill: I've heard this has been changed in newer versions of Debian/Ubuntu, so this step may no longer be necessary. If you don't have the latency problem with truncated final syllables, just skip this step.)

I fixed this by downloading the source code for eSpeak and compiling it for runtime, which uses PulseAudio if it's running and PortAudio otherwise.

I went to http://espeak.sourceforge.net/download.html and downloaded the file espeak-1.46.02-source.zip.

I had to install the library development packages for PulseAudio and PortAudio.

$ sudo apt-get install libpulse-dev libportaudio-dev

Now after unpacking the source code for eSpeak, I went into the source directory, espeak-1.46.02-source/src, and I made the following changes to the Makefile:

#DATADIR=/usr/share/espeak-data
DATADIR=/home/chaltain/Tools/share/espeak-data

#PREFIX=/usr
PREFIX=/home/chaltain/Tools

# 'runtime' uses pulseaudio if it is running, else uses portaudio
AUDIO = runtime
#AUDIO = portaudio

Now I run the commands:

$ make all
$ make install

This creates new eSpeak libraries and binaries, using the runtime option, and places them in my ~/Tools directory.

Now to start Emacspeak with eSpeak and these new libraries, I run the commands:

$ export LD_LIBRARY_PATH=/home/chaltain/Tools/lib
$ emacspeak -e

aNow Emacspeak comes up and I don't have the latency issues.

I ended up adding the line

export LD_LIBRARY_PATH=/home/chaltain/Tools/lib

to the file /usr/bin/emacspeak.

Note that I exported the variable LD_LIBRARY_PATH instead of running the following command:

$ sudo ldconfig /home/chaltain/Tools/lib

so that I'd only run emacspeak with this new library and not making the change globally, so as not to impact Orca if I did something wrong.

When using ldconfig, note you can use

$ ldconfig -p | grep espeak

to see which eSpeak library is being used.

**** Getting Emacspeak with eSpeak to use an US English voice

Based on a tip I saw in a mailing list thread, I went into the file /usr/share/emacs/site-lisp/emacspeak/servers/linux-espeak/tclespeak.cpp, and I commented out the following line in the preferred languages section:

"en-uk", // english

and I added the following line:

"en-us", // english-us

I than ran $ sudo make.

After doing this, I no longer needed the line

(setq espeak-default-voice-string 'en-us)

in my ~/.emacs file.

Maybe if I'd just added the line for en-us then this variable setting might have been needed.
