Speech recognition using Julius and Python in Ubuntu 14.04.2

In this section, we will see how to install the speech recognition system of Julius and how to connect it to Python. The required packages (such as Julius and audio tools) are available in Ubuntu's package manager, but we also need to download and install the Python wrapper separately. Let's start with the required components for the installation.

Installation of Julius speech recognizer and Python module

The following are the instructions to install Julius and Python binding in Ubuntu 14.04.2:

The following command will install the speech recognition system of Julius:
```
$ sudo apt-get install julius
```
The following command will install padsp (the pulse audio tool). It may be necessary to run the Julius speech recognizer in Ubuntu 14.04.2:
```
$ sudo apt-get install pulseaudio-utils
```
The following command will install the OSS proxy daemon to emulate the OSS sound device and stream through the ALSA device. It will emulate the /dev/dsp device...
