Julius step by step – Step 1 – Instalation


Today I would like to add article about Julius voice recognition tool for Linux/Windows systems. I won’t cover Windows related details because it’s out of scope of my interest. Julius Open-Source Large Vocabulary CSR Engine which is in simply manners tool that can give you power of voice recognition. I realized that it’s quite difficult to install and use it so that’s the reason why I would like to wrote few posts just to have reference of few working examples which can make myself happy guy after for example hard drive failure(I would need to apply all settings one more time for the top of my head which would be probably a pain).

Installation process is simple and contains the following points:
1. Download the newest source tarbal from Julius official site – link
2. Unpack the archive for example to your user home directory
3. Configure and install julius by following commands:

cd ~/julius-4.2.2/
sudo ./configure
sudo make
sudo make install

4. Try it by typing in command line:

Julius rev.4.2.2 - based on 
JuliusLib rev.4.2.2 (fast)  built for i686-pc-linux

Try '-setting' for built-in engine configuration.
Try '-help' for run time options.

5. Last additional thing needed to run Julius smoothly is a julius-voxforge package which can be installed via apt-get by typing in command line:

sudo apt-get install julius-voxforge

That’s all now you can start to configure it, because it’s not coming configured just out of the box. I’ll write a post in next few days about basic configuration to which link will be added here.

I would be thankful if You leave comment if you like it :)
