You need to include a speech recognition library. AFAIK Its not built in. Try searching for a library which implements the standard API which suits your needs. -

is not available on the classpath. You might have misplaced you speech recognition jar (java library containing speech recognition specific classes) containing this class. Check out on that.

Try the 'FreeTTS' implementation and get the JSAPI implementation from within the package. I don't remember that JSAPI was provided with the regular JDK, but I could be wrong.

The src zip file contains the and JSAPI.exe script with a readme on how to make it available.

i HAVE installed freetts, but still I am not able to import the classes. Please help - Ankit

When you get the FreeTTS, there's a LIB folder in it. In there, you will find a JSAPI.exe file or a script that you need to run. It will unpack the file 'jsapi.jar'. You then only need to use this jar file and reference it from your ant, eclipse, maven or whatever else you might be using. - user1054394

thanks, i ran the file and some files might have populated in the directory. I am not sure how do i import the files to eclipse. Any help, please? - Ankit
