Linux: Download HTK, Julius & Audacity

Click here for the Windows version of this How-to 

HTK

HTK's licence requires you to register before you can download the toolkit.   The software is open source but there are limitations on the distribution of the HTK Toolkit itself.  However, there is no limitation on the distribution of the models you create with the toolkit.

Step 1 - Register with HTK 

Step 2 - Download HTK Toolkit and Samples

Create a new directory in your home directory called 'bin', it should have the following path (replace 'yourusername' with the user name you are using on your system):

  • /home/yourusename/bin 

click the following links:

and save them to your new bin directory.

Step 3 - Download HTK Book

Click the following link: 

and save it to your new bin directory.

The HTK book is an excellent reference to the toolkit commands.  However, it is written for speech scientists and can be very confusing to beginners.

Step 4 - Unpack you source files

Extract the files using:

  • Nautilus (right click each tar/gzipped file and click extract here); or
  • use tar from the command line for the following files:
    • tar -xvzf HTK-3.4-alpha.tar.gz
    • tar -xvzf HTK-samples-3.4-alpha.tar.gz
    • tar -xvzf htkbook_html.tar.gz

this should create the following directories in your bin folder:

  • htk-3.4
  • samples
  • htkbook
move the 'samples' and 'htkbook' directories to your htk-3.4 folder.

Step 5 - Compile & Install HTK

Compiler version

If you have a newer version of the gcc compiler (version 4 or above), you will need to install gcc version 3.4 compatibility modules so that HTK will compile properly. Use gcc's version command to see which version is installed on your system:

$gcc -v

Target: x86_64-redhat-linux
Configured with: ../configure --prefix=/usr --mandir=/usr/share/man --infodir=/usr/share/info --with-bugurl=http://bugzilla.redhat.com/bugzilla --enable-bootstrap --enable-shared --enable-threads=posix --enable-checking=release --with-system-zlib --enable-__cxa_atexit --disable-libunwind-exceptions --enable-languages=c,c++,objc,obj-c++,java,fortran,ada --enable-java-awt=gtk --disable-dssi --enable-plugin --with-java-home=/usr/lib/jvm/java-1.5.0-gcj-1.5.0.0/jre --enable-libgcj-multifile --enable-java-maintainer-mode --with-ecj-jar=/usr/share/java/eclipse-ecj.jar --disable-libjava-multilib --with-cpu=generic --build=x86_64-redhat-linux
Thread model: posix
gcc version 4.3.0 20080428 (Red Hat 4.3.0-8) (GCC)


If you have version 4.0 or above (I have version 4.3.0) use yum to install the required files to your system:

$su

#yum install compat-gcc-34-c++ compat-gcc-34

32-bit Systems

After unpacking the sources, open a command line terminal and go to the /hom/yourusername/bin/htk3.4 directory where you downloaded your files. 

configure 

The default location for binaries is "/usr/local" which will put the tools in "/usr/local/bin".  You need to change this default location using the "./configure" script to specify where you want the binaries installed:

$./configure --prefix=/home/yourusername/bin/htk-3.4

This directs the make command to put all your binaries in the following folder:

  • /home/yourusername/bin/htk-3.4/bin.linux

64-bit Systems

After unpacking the sources, open a command line terminal and go to the /hom/yourusername/bin/htk3.4 directory where you downloaded your files. 

You now need to install 386 compatibility versions of some development libraries:

$su

#yum install glibc-devel.i386 libX11-devel.i386

configure 

The default location for binaries is "/usr/local" which will put the tools in "/usr/local/bin".  You need to change this default location using the "./configure" script to specify where you want the binaries installed:

$./configure CC=gcc34 --prefix=/home/yourusername/bin/htk-3.4

This directs the make command to put all your binaries in the following folder:

  •  /home/yourusername/bin/htk-3.4/bin.linux

make 

To build the libraries and binaries, execute the following:

$make all

Running the following command will install them: 

$make install

Step 6 - Copy required HTK Perl Scripts

Create a new directory called "HTK_scripts" in your voxforge folder, it should have the following path:

  • /home/yourusename/voxforge/HTK_scripts 

Copy the following HTK scripts to your newly created 'HTK_scripts' folder:

  • mkclscript.prl (located in /htk-3.4/samples/RMHTK/perl_scripts folder)
  • maketrihed (located in /htk-3.4/samples/HTKTutorial folder)
  • prompts2mlf (located in /htk-3.4/samples/HTKTutorial folder)
  • prompts2wlist (located in /htk-3.4/samples/HTKTutorial folder)

Julius

Julius has no limitations on distribution.  It uses Acoustic Models in HTK format, and Grammar files in its own format.  

Julius is a large vocabulary continuous speech recognition (LVCSR) engine.  Julius is used in dictation applications.

Julian is a special version of Julius that performs grammar based speech recognition.   Julian is used for command and control applications.  

We will be using the Julian version of Julius for this tutorial.

Step 1 - Download Julius

click the following link: 

and save it to your '/home/yourusename/bin' directory.

(note: if you want to compile Julius from source, see this FAQ entry) 

Step 2 - Extract Julius 

Extract the file using:

  • Nautilus (right click the tar/gzipped file and click extract here)
  • use tar from the command line:
    • tar -xvzf julius-3.5.2.tar.gz
this should create a julius-3.5.2 directory in your bin folder.

Update User Path

To update your user path, you need to add the following directories your user path variable:

  • /home/yourusename/bin/htk-3.4/bin.linux;
  • /home/yourusename/bin/htk-3.4/lib.linux; and
  • /home/yourusename/bin/julius-3.5.2-multipath-linuxbin/bin.

To do this, edit your '.bash_profile' file in your home directory (in Fedora you need to show 'hidden files' in Nautilus - so you can display file names with a period in front of them). You do this by adding the listed paths, separated by a colon (":") to the end of the PATH variable as follows (all one line, no spaces):
 

# User specific environment and startup programs
PATH=$PATH:$HOME/bin:/home/yourusename/bin/htk-3.4/bin.linux:
home/yourusename/bin/htk-3.4/lib.linux:
/home/yourusename/bin/julius-3.5.2-multipath-linuxbin/bin

Log out and log back in to make your path change effective.

Testing Your HTK/Julius Install

  • Type in "HVite -V" in a Command Console Window;
if your system lists all the options available to the hvite command, then HTK is installed properly.
  • Type in "julian" in a Command Console Window;
if your system displays version information for Julius, then Julius is installed properly;
  • If you don't see the expected results, review your installation steps for Julius or HTK to determine where you might have made an error.

Audacity

If you are using Linux (we will be using the Fedora for these tutorials) use the following command to download and install Audacity (as superuser):

$su
Password:
#yum install audacity

Compiling 64-bit HTK
By kmaclean - 1/4/2010 - 1 Replies

From the HTK mailing list (I have not tried this yet...):

Yes, on 64-bits the GCC compiler use -m64 to generate binary files for 64-bit architecture, also add -L options with the path for the libraries like X11.
That should solve your problems.

Regards,
Vitorio.

Can not execute 'julian'
By daFunkyUnit - 11/10/2009 - 1 Replies

I am running on Mac OS X 10.5.8, and I cannot execute the julian command, saying that it "cannot execute binary file."


I un-tar'ed julius-3.5.2-multipath-linuxbin in where my HTK is installed, and I have added paths for HTK and julius into the $PATH environment variable.  I have checked the permissions for all the files in the julius-3.5.2-multipath-linuxbin/bin directory and they all are "-rwxr-xr-x" so they all should be executable. But I can not execute any of the commands, except for the perl scripts (gram2sapixml.pl, mkdfa.pl, yomi2voca.pl)

Please help!

Thanks,
-bao

question
By toothdoc - 7/19/2009 - 1 Replies
1. from Windows Explorer, use a Cygwin editor (such as Vim) to edit:
c:/cygwin/etc/bash.bashrc
and add the following lines:  
PATH=/Julius/bin:/HTK/htk-3.3-windows-binary/htk:$PATH
export PATH

There is no bash.bashrc file in etc folder. What am supposed to do now? Did I do something wrong?

compiling HTK using Microsoft Visual Studio
By kmaclean - 6/17/2009

From this post: Installing HTK on Microsoft Windows(음성인식 software)

Prerequisites

  • HTK has been verified to compile using Microsoft Visual Studio.
  • For testing, you will require a Perl interpreter such as ActivePerl.
  • You will need a tool such as 7-zip for unpacking the HTK source code archive.
  • Register on this site by accepting the HTK End User Licence Agreement, then download the latest HTK source code.
  • It is helpful if you have some familiarity with using the DOS command line interface, as you will need to interact with it in order to compile, install and run HTK.
  • Ensure that your PATH contains C:\Program Files\Microsoft Visual Studio\VC98\bin

Compilation

  1. Unpack the HTK sources using 7-zip.
  2. Open a DOS command window: Click Start, select Run type cmd at the prompt and click OK.
  3. cd into the directory in which you unpacked the sources.
  4. cd into the htk directory. Type: 
    cd htk
  5. Create a directory for the library and tools. Type: 
    mkdir bin.win32
  6. Run VCVARS32 (it should be in your path, see prerequisites above)
  7. Build the HTK Library, which provides the common functionality used by the HTK Tools. Enter the following commands:
    cd HTKLib
    nmake /f htk_htklib_nt.mkf all
    cd ..
  8. Build the HTK Tools
    cd HTKTools
    nmake /f htk_htktools_nt.mkf all
    cd ..
    cd HLMLib
    nmake /f htk_hlmlib_nt.mkf all
    cd ..
    cd HLMTools
    nmake /f htk_hlmtools_nt.mkf all
    cd ..

Installation

The HTK tools have now been built and are in the bin.win32 directory. You should add this directory to your PATH, so that you can run them easily from the command line in future.

make install fails
By RobotJay - 2/24/2009 - 1 Replies

I finally got the "make all" command to (seemingly) work.  Now, when I run "make install" I get the following error:

jay@######:~/bin/htk$ make install

make[1]: *** [mkinstalldir] Error 1
make[1]: Leaving directory `/home/jay/bin/htk/HTKTools'
make: *** [install-htktools] Error 1

I can't find any help for this anywhere, so I'd appreciate any you can offer.  TIA.

-Jay

P.S. I'm running Ubuntu Intrepid Ibex on a 32-bit system.

Additional Instructions to compile HTK on Ubuntu 8 (Hardy)
By psthomas@gmail.com - 12/2/2008 
Okiedokie people, Here are some solutions to a number of problems that I saw people having (myself included):
Alternate Ubuntu Directions for Step 5 above (from a mostly clean Hardy install):
1) You'll need gcc 3.4 (as mentioned)
2) Use synaptic or apt to get: 
 - cpp-3.4 
 - gcc-3.4 
 - gcc-3.4-base
3) Try to run configure.
4) If you see an error like "configure:1799: error: C compiler cannot create executables" then it's probably because you're missing some link libraries. Use synaptic/apt to get:
 - libc6-dev
4) Try to "make all" 
5) If you see an error like "HGraf.c:73:77: X11/Xlib.h: No such file or director", then you need:
 - libx11-dev
6) Now "make all" should succeed.

Hope that helps!

Makefile Errors?
By Ramen - 8/8/2008 - 1 Replies

I am trying to follow the instructions listed above for installing HTK.   I am using a 32-bit system.  I get as far as running

$./configure --prefix=/home/yourusername/bin/htk-3.4

But when I try to run make all, I get about 800 errors. At the top of the list of errors, my terminal says,

"HGraf.c:73:77: error: X11/Xlib.h: No such file or directory
HGraf.c:74:23: error: X11/Xutil.h: No such file or directory
HGraf.c:75:21: error: X11/Xos.h: No such file or directory
HGraf.c:77:27: error: X11/keysymdef.h: No such file or directory"

and then it has several lines of stuff looking like,

"HGraf.c:87: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘*’ token"

 Does anyone know what's going on here/how I can fix this?

 

By the way, I coculd not find a module to make my version of GCC compatible with 3.4.  Instead, I simply downloaded GCC 3.4 and edited the Makefile so that it would run GCC 3.4 instead of my new version of GCC.

 

Thanks!

error in compiling julian
By amza - 1/7/2008 - 2 Replies

I compile julian from source (julius-3.5.2.tar.gz, and then extracts it), because I need julian, not julius, by typing the command as follows:

$./configure --prefix=/home/riset/bin/julius-3.5.2  --enable-julian

The compile didn't work well because there are errors as follows:

$ ./configure --prefix=/home/riset/bin/julius-3.5.2 --enable-julian >a.txt
./configure: line 1033: cmp: command not found
./configure: line 714: cmp: command not found
configure: warning: no iconv, gram2sapixml.pl may not work
./configure: line 1331: cmp: command not found
./configure: line 1203: cmp: command not found
./configure: line 2009: cmp: command not found
configure: warning: not found
configure: warning: libsndfile enables AIFF AU SND NIST format for Julius.
It's available at http://www.mega-nerd.com/libsndfile/
./configure: line 3094: cmp: command not found

I don't understand the command "cmp" in "configure" file, because the file is already available. Can you help me? I haven't been able to run julian yet since 3 weeks ago.  Thank you.

It is about installation of htk.I already have htk installed on my linux system,but the location of installation is different from the steps specified on this tutorial.I have tried installing multiple copies but it did not work.

Since htk has already been installed and working,can I skip the section on htk and focus on other parts of the tutorials or must it be installedfollowing your steps.
