Speech Recognition By Java - Simplified



Speech recognition is one of the challenging areas in computer science, a lot of pattern recognition methodology tried to resolve a good way and higher percentage of recognition.

One of the best ways to be use is Hidden Markov Model :



"The process of speech recognition is to find the best possible sequence of words (or units) that will fit the given input speech. It is a search problem, and in the case of HMM-based recognizers, a graph search problem. The graph represents all possible sequences of phonemes in the entire language of the task under consideration. The graph is typically composed of the HMMs of sound units concatenated in a guided manner, as specified by the grammar of the task."

There are a lot of Java Based Speech Recognition Engines, you can find them here:

http://ocvolume.sourceforge.net/links.php.

In this post we will select one of the famous open source Java speech recognition software and identify simple steps to use it.

Sphinx-4

Sphinx-4 is a state-of-the-art speech recognition system written entirely in the JavaTM programming language. It was created via a joint collaboration between the Sphinx group at Carnegie Mellon University, Sun Microsystems Laboratories, Mitsubishi Electric Research Labs (MERL), and Hewlett Packard (HP), with contributions from the University of California at Santa Cruz (UCSC) and the Massachusetts Institute of Technology (MIT).

Sphinx-4 started out as a port of Sphinx-3 to the Java programming language, but evolved into a recognizer designed to be much more flexible than Sphinx-3, thus becoming an excellent platform for speech research.


1) Download the software:

Here is the download link:

http://sourceforge.net/projects/cmusphinx/files/sphinx4/1.0%20beta6/sphinx4-1.0beta6-bin.zip/download.

2) Create new Java project:

Add to class-path 3 jars from the lib folder:
jsapi.jar (if not exist jsapi.exe will extract it on windows or jsapi.sh will extract it)
sphinx4.jar (APIs Jar)
WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar (this is the jar containing the speech)


3) Create a new class to write the logic on it: e.g. ListenToMe.java
Let the package name osa.ora

4) Add the file dict.gram to the same package: osa.ora
It should looks like:
#JSGF V1.0;
grammar hello;
public <greet>= (Good morning | Hello | Hi | Welcome) ( Osama | Paul | Philip | Rita | Will );

The structure is to write the alternative words between () and separated by | and give them tag name to describe these words (greet here).

The grammar specs in this URL:
http://www.w3.org/TR/jsgf/
A quick tutorial in this URL:
http://puneetk.com/basics-of-java-speech-grammar-format-jsgf


5) Add the config file myconfig.xml to the same package: osa.ora
You can get the file structure from the jar in bin folder HelloWorld.jar
in the location "HelloWorld.jar\edu\cmu\sphinx\demo\helloworld\helloworld.config.xml"

You need to edit the following entry:
<component name="jsgfGrammar" type="edu.cmu.sphinx.jsgf.JSGFGrammar">
<property name="dictionary" value="dictionary"/>
<property name="grammarLocation"
value="resource:/osa/ora/"/>
<property name="grammarName" value="dict"/>
<property name="logMath" value="logMath"/>
</component>

6) Write the following code in the created class:

import edu.cmu.sphinx.frontend.util.Microphone;
import edu.cmu.sphinx.recognizer.Recognizer;
import edu.cmu.sphinx.result.Result;
import edu.cmu.sphinx.util.props.ConfigurationManager;

public static void main(String args[]){
ConfigurationManager cm = new ConfigurationManager(ListenToMe.class.getResource("myconfig.xml"));
Recognizer recognizer = (Recognizer)cm.lookup("recognizer");
recognizer.allocate();
Microphone microphone = (Microphone)cm.lookup("microphone");
if(!microphone.startRecording()){
System.out.println("Cannot start microphone.");
recognizer.deallocate();
System.exit(1);
}
System.out.println("Say: (Good morning | Hello | Hi | Welcome) ( Osama | Paul | Philip | Rita | Will )");
do {
System.out.println("Start speaking. Press Ctrl-C to quit.\n");
Result result = recognizer.recognize();
if(result != null) {
String resultText = result.getBestFinalResultNoFiller();
System.out.println((new StringBuilder()).append("You said: ").append(resultText).append('\n').toString());
} else {
System.out.println("I can't hear what you said.\n");
}
} while(true);
}


As you can see you can use ConfigurationManager to re-set the grammarName to dict1 , dict2 ,..etc, you can also have multiple configurations.

For more details about the usage you can refer to this URL:

http://cmusphinx.sourceforge.net/sphinx4/

You may use Interactive4J implementation direct to achieve dynamic voice recognition.. Find more details here.

  3. You must add this jar to the classpath:

  18. osama i need to add this words to my app(category-next-previous-select- sub category- product-go category-feature product-go first category)
    please did you send to me your mail in<azza_az20@yahoo.com)to send to you my application to edit this words
    i need this quickly because it is part of graduation project and it will deliver in 21/7 pleas osama help me quickly\
    thanks for you

    ReplyDelete
  19. My advice is to keep 1 word for each command : remove "go" for example also remove category so your dictionary looks like : First, Feature, Category, Product, Sub, Select, Next, Previous

    Try the application and remove the dominant words and replace them with alternatives with the same meaning. like Previous --> Back , Next -->Move ,...etc.. until you get the best results possible.

  23. What if I want to use Arabic words in the grammar
    Thanks

    ReplyDelete
  24. The correct way is to have a new language that support this implementation for Arabic because this current implementation for English, so i advice you to search for another way if you need it quickly as this need a lot of time and effort plus a big team work to develop it.

  26. The exception said file not found , so either file is not found in the mentioned location or corrupted , you need to include it in your class path , this jar is part of Sphinx4 library:

  27. Hello Mr Osama..
    Thank you for reverting back
    I have tried that again but getting the same exception
    even i tried to compile and run the Helloworld example provided with sphinx, the file compiles with but fails to run with same exception
    the strange thing is that the compile jar(i.e Helloworld.jar) provided with sphinx runs well,
    is there any way to get help or running example
    Thanks

    ReplyDelete
  28. I guess this is because the Jar exist in the same folder with HelloWorld jar file so it run without any issues.

    1. Maybe I know what is the problems about the .xml file ?

      If I follow your example above, it should be the path location causes the null pointer exception. thanks in advance.

    2. May I know what is the problem for the netbean project? I'm think it's the .xml file can't find the location path. If I follow the example above, it causes null pointer exception, I'm think the problems occurred in .xml file because the path is not defined correctly. thanks in advance.

      Delete
    3. I checked your file, the path is invalid and the filename as well ..
      resource:file:C\\Users\\User\\Documents\\NetBeansProjects\\osa.ora\\

      the prefix resource: means it is a resource inside the jar so use relative path as in my example, in your project you didn't define a package for your java classes (this is not good) any way the value should be in that case resource:/

      the filename in your example is : hello.gram so the other value:
      <property name="grammarName" value="hello"/>

    ReplyDelete
  70. SOLUTION:
    The problem here for most of you is the grammar line:
    public = (...

    You think it's "public = (...". It's not.

    There is a "greet" element after the word public.
    It can't be seen (on Firefox, at least).
    However, you can see it if you right click on the browser and view the page source.

    This is the actual code: public <greet> = (...
