java speech api

[arpandixit]

hi! i am trying to build an application which will recognize speech and convert into text.For that i have installed jdk 1.6, Apache ant 1.8, sphinx4-1.0beta3-src and also set the paths etc. i am able to run the demos like given in C:\Program Files\Java\sphinx4-1.0beta3-src\sphinx4-1.0beta3\bin\HelloWorld.jar using java -mx256m -jar bin/HelloWorld.jar which is already built classes but if i am trying to compile the java the same java program HelloWorld.java wiith its grammar.gram file its giving me errors

Isn't it kind of obvious? :D You dont have the javax.speech package, for that you need to download the JSAPI.jar, I dont think you are allowed to post download links here, but either ways some simple googling would suffice. In order for you to use it properly though, you might need an IDE like eclipse or netbeans. You can automatically import it from them ,and use it.

My note of warning to you, just using the demo CODE they supply might not work, I have tried speech recognition myself, it is NOT as easy as it seems, and is prone to error a LOT. If you do manage to get it working, I would suggest posting a tutorial, it can help others :) Good luck!

thanx for replying. I ve already downloaded sphinx which is containing jsapi.jar and i ve already set the environment variables but it's not wrking. I also copied the speech folder after xtracting from this jar file nd put it into the javax folder in jdk.bt still it's not working...plz help

Oh I see, infact your post intrigued me about Sphinx, I have always seen it, but never tried it, I followed their directions very closely, doing everything just like they said. It just seems not to work, no matter what I tried as well, not even the regular jars in the precompiled BINs worked properly. It seems to me that speech in java is just something beyond our control, at least at the moment. If I figure out a solution, I will tell you ;) :D

thanx man..plz let me know if find so..

You need to do three thing:

1. What you need to do is you need to install the recogniser engine you need to download it from
   http://cloudgarden1.com/TalkingJavaSDK-170.zip

2. After downloading it extract it and copy two files cgjsapi.jar,cgjsapi170.dll to \jre\lib\ext.

3. Add this code to register your recogniser & speech engine.
   Add this code above any code inside the main

   public static void main(String args[]) {
   try {
   //Set the sound Properties
   System.setProperty("freetts.voices", "com.sun.speech.freetts.en.us.cmu_us_kal.KevinVoiceDirectory");

   Central.registerEngineCentral
   ("com.cloudgarden.speech.CGEngineCentral");

If these code worked for just let me know..... :-)
Thanks.

Kind regards
