Speech recognition: Using julius and voxforge

Usage of the basic and shutdown program

=======================================

First the grammar and vocabulary need compilation. To compile the 

mkdfa.pl script should be used. Note: On Ubuntu it is called mkdfa 

in stead of mkdfa.pl.

```

mkdfa.pl basics_and_shutdown

```

Run julius with the control script as

```

julius -C basics_and_shutdown.jconf | ./basics_and_shutdown.py

```

As you can see the control script is written in python v2.

Currently the syntax requires you to identify your computer as Lux 

(spoken as: looks), Lacer (spoken as: lazer), Alexia, or Pi.

After the identification follows a command. The following commands are 

possible:

Volume Control

--------------

Volume control uses amixer to set the Master volume.

* volume up/down

* volume 1,2,3,4,5,10,15,...,100

mute executes the commands amixer set Master toggle. Synonyms are:

* mute

* unmute

* shut up

* silence

Music Player Commands

---------------------

The command script separates whether Alexia,Pi, or Lux,Lacer is used 

for identification. For Alexia and Pi, the commands correspond to the 

respective mpc commands. For Lux and Lacer, rhythmbox is used.

* next

* previous

* pause, unpause (spoken as: unpaw)

* stop

shutdown

--------

The following commands can be used to turn off, or prevent the 

previously commanded shutdown. Shutdown occurs in one minute.

* shut down (two separate words)

* cancel shut down (cancel with American pronunciation)

In order to allow for shutdown without password entry add the following 

line to your /etc/sudoers file. Replace user_name appropriately.

```

%user_name ALL=(ALL) NOPASSWD: /sbin/poweroff /sbin/reboot /sbin/shutdown

```

ISSUES

======

Currently we are unable to prevent julius from outputing the most likely 

command if no good match is found. Due to this reason the ID tag 

contains a number of ERROR outputs. This works for the moment.

The second big issue we encountered is due to to ambient noise level. 

Julius does not differentiate between sound output coming from the 

computer and external sounds. Using headphones there is no issue however 

with satellites louder volume can obstruct the required  tag at the 

beginning and end each identification.
