For those of you confused about step 7: Run the “HelloWorld.jar” from the command line (if in windows, it will look something like this):

java -jar HelloWorld.jar

This should spit out some text output that will tell you where your speech.properties file needs to go. Here’s the output from mine:

C:\Users\Nicholas\Downloads\freetts-1.2.2-bin\freetts-1.2\bin>java -jar HelloWorld.jar

All general Mode JSAPI Synthesizers and Voices:

Using voice: kevin16
No synthesizer created. This may be the result of any
number of problems. It’s typically due to a missing
“speech.properties” file that should be at either of
these locations:

user.home : C:\Users\Nicholas
java.home/lib: C:\Program Files\Java\jre6\lib

Another cause of this problem might be corrupt or missing
voice jar files in the freetts lib directory. This problem
also sometimes arises when the freetts.jar file is corrupt
or missing. Sorry about that. Please check for these
various conditions and then try again.

Hi ,I am an engineer trying to use freetts on Java Speech API . I followed your instructions above and i dont get any error on netbeans. However I dont get any audio either. I modified the code slightly and noticed the program hangs as illustrated on the code snippet below
import javax.speech.*;
import javax.speech.synthesis.*;
import java.util.Locale;
public class helloWorld {
public static void main(String args[]) {
try {
// Create a synthesizer for English
Synthesizer synth = Central.createSynthesizer(
new SynthesizerModeDesc(Locale.ENGLISH));
System.out.println(”aaaaaaaaaaa”);
// Get it ready to speak
synth.allocate();
System.out.println(”bbbbbbbbbbb”);
synth.resume();
System.out.println(”ccccccccccc”);
// Speak the “Hello world” string
synth.speakPlainText(”Hello, world!”, null);
System.out.println(”dddddddddddd”);
// Wait till speaking is done
synth.waitEngineState(Synthesizer.QUEUE_EMPTY);
System.out.println(”eeeeeeeeeeee”);
// Clean up
synth.deallocate();
} catch (Exception e) {
e.printStackTrace();
}
}
}
The output i got was
System property “mbrola.base” is undefined. Will not use MBROLA voices.
aaaaaaaaaaa
bbbbbbbbbbb
ccccccccccc
dddddddddddd
so the program hangs was wondering why.
I am using Ubuntu 9.10 and Netbeans 6.9.1

i have the same problem where install the voices..?? and where i can download the voices to work…:S thk..
