Hello All,
This is my first video tutorial. This tutorial demonstrates how to make a speech recognizer in java using Sphinx.
Requirements to work according to the tutorial :
1 ) JDK 6 ( J2SE )
2 ) Eclipse SDK ( Im using Eclipse 3.4.0 )
3 ) Sphinx 4.0
4 ) JSAPI ( Included in Sphinx 4.0 )
Tutorial is divided into 3 parts.
Please feel free to post your comments and suggestions on tutorial and help me to improve the quality.

Hi Mr. Kalra,
your video tutorials for Speech Recognizer In Java are extremely useful. trouble is the quality of the video is poor, no offend, which makes it hard to follow your steps. Could you post a higher video quality ? that would really helps.
cheers,

Hi Kalra,
thank you so much for this tutorial. it was really helpful thanks again……..
I need to use SphinxTrain in sphinx4 I want to do the training for sphinx4 to be able to recognize some words. if you have done it before i will be very happy if you can help me…..
thanks
Hello Liliane,
Thankyou.
SphinxTrain, Well I would like to know the exact reason first. Do you want to add few more words to dictionary ? Or we can say, Do you want Sphinx to recognize few more words not available in default acoustic models provided by CMU ?
If this is the reason and words are only a few, then I would suggest you Not to use SphinxTrain as its a big process.
I have another way to do it. If I’m correct on the reason. Let me know, I will tell you how to do it.
Regards.
hi Kalra
thank you for your prompt reply…..
I want to create an Automated Speech Recognition System (ASR) based on the open source sphinx-4, so I want to investigate the changes that must be made to the acoustic model to be adapted for my application.
but I can start by adding just few more words in the acoustic model to see how it’s work. I will be grateful if you can help to do it…..so please could you tell me your way to do it smart man……..
after that we will see if you can help me for sphinxTrain or any other tools to add a big corpus to the acoustic model of the sphinx-4…
thank you so much.
Regards
hello,
I forget to tell that some person they use HTK and ATK to create the speech recognizer.I’am stuck and I didn’t find any tutorial with all steps , i’am usin windows vista and i notice that most of them are using Linux as OS ………..I’m depressing
thanks in advanced for your help……….
Regards
Hello again,
Alright. I will be posting my tutorial publicly in few time. So it will be available for others too. This is just a small but important part of developing an ASR.
Developing ASR, you need to consider on configuration part of Sphinx. Not how you write the config file. Important thing is, Which components and properties you should use, Like, absolute and relative BeamWidth, languageWeight, searchGrams, Linguist, languageModel etc.
To understand these things, you need to learn algos and background working of Recognition. For that, i suggest you to read any good book on ASR.
Even, im not expert on ASR, I’m just another student of ASR and i hope together we both can gain more better knowledge and create a better system.
Again, I will be posting tutorial soon.
Regards,
hello Kalra,
Great smart man, it’s a good news so waiting for your interesting tutorial as usual………
I have a background in ASR but I didn’t practice it because I’m try to learn alone and i didn’t take any courses ………..
thanks again

Hello Kalra,
i just wonder which language Sphinx supports.
U said that you read a good book, so can u tell me that book’s name.
Can I use Sphinx to recognize Vietnamesse? I come from Viet Nam.
Hello Khanh,
Sphinx supports all languages as long as you have acoustic model for that language. Search on web if you can get any Vietnamese acoustic model.
You know, I have been to Vietnam once, I was living in Cambodia before.
Best of luck!
I’m realy not clear about acoustic model.
Could u give me few instructions to build an small app with a small vocab, something like what i need to do firt, and then … I just want my computer hears some simple sentences.
Sphinx supports all languages. How lucky I am! Maybe I could build a good speech recognition engine for my language, in far future!

In your second & third video….can you please tell me how you have setup VM variables and arguments? The variables were hard to get because of poor video graphics.
Please reply as soon as possible, i have a project on this.
Can you please write a .gram file which can recognize any word in the output?
Hello Dishant,
All you have to do is, change the java heap size to 256MB, for that you can use “-Xmx256m” or “-Xms256m”, something like
java -Xmx256m AppStarter

we are working on a speech translator.we are done with two modules.for synthesis we have used freetts. In the recognition part we have saved all the required classes in our jdk, we get a NullPointerException for the line where we allocate recognizer. is there any other tool like freetts which we can be using for recognition.
