help me : i am new to sphinx

[Ramki Balakrishnan]

i am doing my project with speech recognition concept. i tried sphinx. but i do not know how to install sphinx in xp. i tried that wave file demo jar file. but the output is unable to access the jar file. thanks in advance

[Kurt Liska]

Greetings all,

I am a marketer, not a programmer/engineer, so please excuse in advance...

1. where can I find information about Sphinx which is written in layman's language?

2. where can I discover a listing of existing projects so that I can determine if anyone is already doing what I am interested in?

3. does anyone know if there are forums which help people like me (marketer/entrepreneur) to find engineer partners?

> but i do not know how to install sphinx in xp.

Try to setup sphinx4 in IDE

http://cmusphinx.sourceforge.net/sphinx4/doc/Eclipse.html

or there is a similar document for netbeans

[Ramki Balakrishnan]

but in sphinx documentation they mentioned to use cygwin in xp to use the sphinx. tried that also. but i could not run that demos.

Hi!
About year ago i was using Sphinx4 and everything worked just fine. Unfortunately i had to reinstall my system and now i'm trying to setup sphinx in NetBeans and i get weird errors. I tried on Vista and XP [on my laptop and PC] with NetBeans ver 6.5, 5.5 and 5.0 on both windows. I have latest java SDK 6.12. and apache-ant-1.7.1. I've downloaded both scr and bin sphinx. Demo jars run in console works fine but i can't build it in NetBeans. I did everything step by step from http://cmusphinx.sourceforge.net/sphinx4/doc/NetBeans.html and when i'm trying to open java file in any demo it has weird erros:
When i double click on HelloDigits.java the import part is underlined in red and it says that's there is no package about those:

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;
import edu.cmu.sphinx.util.props.PropertyException;

But i have the edu folder imported at the beginning.

My 1st question is about building sphinx in step 'Select JDK 5 in the Source level field. Click on Next button. This will show Java Sources Classpath tab. ' i have nothing in Java Sources Classpath should i add some files there? [i'm adding jar files to classpath later like tutorial says]
When i do in NetBeans build.xml-> Run target -> all there are no mistakes.
So i had an idea i copied build.xml to my HelloDigits folder the package error disappeared but when i do build.xml-> Run target -> all there are more and more mistakes about missing files and folders from edu and linguistic.
And part in 'Running Sphinx-4 Demos' with editing build.xml is unclear. Perhaps that's the source of my problems.

Last thing. I actually need only working hellodigits that i can add to my other application so according to FAQ i need only bin version of Sphinx. Maybe it's easier to build in NetBeans, because honestly i give. Last year i did a working dictionary window application and i didn't have any problems like i'm facing now.
I'll be greatfull for any help and i'm sorry if my english is not correct but i'm not a native.

[Magdalena Broniecka]

I just figured it out! I was editing wrong build.xml file! Now it seems to be working properly. I usually figure things out right after asking for help. I just got new perspective after posting my problem after so many hours spent with code only.
Anyway perhaps i will need more help in the future with my kind-of-skype with voice-dialing application, because now i need to connect 'telephone part' with dialing numbers.
Goodnight :)

Great everything goes well. If you are a newbie and want to ask questions online, feel free to join #cmusphinx irc channel on freenode.

i run the helloworld program in xp with netbeans 4. its working properly.
but while i run the wavefile program i gives some errors. i modified the bulid.xml file also.

build.xml file:

<?xml version="1.0" encoding="UTF-8"?>

<project basedir="." default="all" name="The hello world demo.">

<description>
This file is used to run the hello world demo.

NOTE: Before running the tests, you must have already built
the sphinx-4 sources by typing "ant" in the top level
sphinx4 directory.

I'm not quite sure why do you modify build.xml. To build wavfile use build.xml in the root of the archive or demo.xml in the root.

[Magdalena Broniecka]

Hi Nickolay, i did same thing i took build.xml from main directory. You should edit the one from helloworld demo. It's short and contains data connected to this helloworld application.

Unfortunately i'm facing another problem. I build jar file for let's say helloworld by adding code to build.xml:
<jar jarfile="${lib_dir}/HelloWorld.jar"
basedir="."
manifest="${basedir}/helloworld.Manifest"
/>
Everything goes great but i can't run the jar file because it says 'Could not find Main Class' I know that probably there is something wrong with manifest:
Main-Class: demo.sphinx.helloworld.HelloWorld
Class-Path: ../lib/sphinx4.jar ../lib/jsapi.jar ../lib/WSJ_8gau_13dCep_16k_40mel_130Hz_6800Hz.jar
But i'm not sure what should i change since i'm using an original demo sphinx files.

Thanks for help in advance or perhaps i will have another eureka in 10 minutes ;)

[Ramki Balakrishnan]

thaks for your quick reply. if i change my build.xml file means how can i run the wavefile program in netbeans. i can run the program by build.xml in the wavefile folder only. please help

[Ramki Balakrishnan]

in the link http://cmusphinx.sourceforge.net/sphinx4/doc/NetBeans.html
they told only to copy the build.xml in the other demos.

[Holger Brandl]

Hi Ramki,

sorry for inconvenience. I've already removed the file because it's not up-to-date anymore. Please follow the instructions at http://cmusphinx.sourceforge.net/sphinx4/#setupide

Best,
Holger

[Ramki Balakrishnan]
