I have a code for speech recognition but it not work good
it has a problem in line 31
what is the solution ???

what is the problem? is it an error or what? if its an error please type out the error message as it will help to understand whats going wrong

this is the error

well, have you checked what JamesCherril told you?
I think that's exactly the problem you are having, based on this stacktrace.

t HelloWorld.main(HelloWorld.java:28)

Which is your line number in the code.
I guess it is this :

ConfigurationManager cm = new ConfigurationManager(new URL("http:\\www.google.com"));

You need to this correction JamesCherill said :

"http:\\www.google.com"

In Java \ is a special character, used to start escape sequences in string literals. "\\" in a string literal is only a single \ character in the String itself.

Use "http:\\\\www.google.com"

Edited 4 Years Ago by DJSAN10: Posted the same time you guys did.. :) :)

OK i do what you tell but i get the same error

but i get the same error

If you can't see that

Exception in thread "main" java.lang.NullPointerException
at edu.cmu.sphinx.model.acoustic.WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.ModelLoader.loadProperties(ModelLoader.java:372)

is NOT the same as

Exception in thread "main" java.lang.IllegalArgumentException: protocol = http host = null

then you may as well give up now.

You fixed the first error and created a completely new one. Maybe you should post the version of the code that gives the second error

there a new version of my project

I am sorry
someone said to me
i have to try a code first on any a valid url then try it on xml file

I'm sorry to bother

I'm sorry but you were given some bad advice there. If it's not the URL of a valid XML config file then, of course, you will get all kinds or errors. Try it with a valid file URL and I'm sure you will make good progress.
J

thank you for your helping
i do what you say
i put the right URL for xml file
but the program can recognize it
and this is the error

Unfortunately the sphinx package you are using was written by idiots who have never heard of error messages.
