Java Speech Recognisation

Dear All,
I�m developing a speech recognizer cum synthesizer project. For that Im using sphinx4 as my recognizer and FreeTTS as synthesizer. Here[u] I need to know can I train my voice in sphinx 4. If yes pls help me.
I�ll be very glad if could find any solution for Heap space problem in Eclipse.
Are there any sites available with reference codes or full code for this?

Java Speech + JSP

Hi
I'm new to the Java Speech API and JSP. Does anybody know if it is possible to use java speech in jsp pages? Somebody told me if you want to use java speech on the web you need to use applets. It that true?
Oh yeah, I'm using the FreeTTS implementation from SourceForge.
Thanks

hi All
i started development on the Java Speech API. so were i can download the jar file and also if any one having the Maven artifact Id / group Id. please post it.it may helpful for me.
Thanks

Sun has no such API like Java Speech API in their J2SE but there r other third parties api like FreeTTS which can be used
to code speech apps.

Java speech recognition software ?

Hi Software Experts.
I have 2 short questions.
1. does any one here have any knowledge of any java speech recognition software ?
2. is it true that all speech recognition software has to be trained ?
Are there some simple ones on the market that will test for 1 word and therefore not need to be trained ? Or trained a lot less ?

IBM makes Via voice, a commercial package. Almost all apps need some training, to be truely effective, as the user's speech patterns vary. I am not aware of any Sun classes for this, there may be some 3rd party classes out there.... - Bart

Hi,
Are you running the Speech over Via Voice runtimes? If you are running it using Via Voice then make sure that your classpaths are set appropriatly pointing to the ibmjs directory where the runtimes are contained. This is usually the problem.

Java Speech stops speaking

I have been able to start the synthesizer and start speaking, however, there have been times when the application just quits speaking. It's still going through the code, you just can no longer here anything. Any ideas on what may be causing this, or what I can do to detect it and start it up again?
Thanks.

can any body help me here
i have windows2000 and installed
Freetts and set jsapi.jar in the
classpath for compiling HelloWorld
speech program and it compiled well,
also i put speech.properties file
without modifying it in my c:\j2sdk1.4\jre\speech.properties
now iam getting error as
Can't find synthesizer.
Make sure that there is a "speech.properties" file at either of these locations:
user.home: C:\Documents and Settings\Administrator
java.home: c:\j2sdk1.4\jre
what could be the problem here. please help me..
thanx.

Java Speech with Netbeans

Having difficulty trying to use netbeans together with FreeTT. Eventhough i have installed FreeTTS i always get error message when i import javax.speech

>
Having difficulty trying to use netbeans together with FreeTT. Eventhough i have installed FreeTTS i always get error message when i import javax.speech>To compile successfully will require that all (the mentioned) Java classes are on the compilation class path.
To run code successfully requires not only the Java classes, but also any natives, to be on the application's run time class path.
How you add the resources to 'netbeans' I neither know nor care (I do not use, nor provide support for, netbeans). OTOH, Netbeans can understand and work with Ant build files, so if you are willing to abandon Netbeans automagic ways of doing things that seem not to work, for compiling and running using an Ant build file, you might find more help around these forums (and specifically from me).
