Java

The following instructions were provided by me on a forum some years back on how to run helloworld for Java Speech API (on Windows platform). I am copying it here again (for my own reference, as well as any other aspirants out there)

Download the freetts library. Extract and follow following instructions to run a HelloWorld program successfully:

1. Unzipped: freetts-1.2.1-bin.zip to a folder, say [freetts]

2. Execute [freetts]/lib/jsapi.exe to obtain jsapi.jar

3. Created a sample 'demo' folder.

4. Copied contents (sound files and HelloWorld.java) of [freetts]\demo\JSAPI\HelloWorld to my 'demo' folder.

5. Copied following files from [freetts]\lib to my 'demo' folder:
freetts.jar
jsapi.jar
cmu_us_kal.jar
cmulex.jar
en_us.jar

6. Copied [freetts]/speech.properties file to my home folder i.e. C:\Documents and Settings\[my_user_name] OR /home/[my_user_name]

7. Compiled HelloWorld program as:
javac -classpath .;./jsapi.jar HelloWorld.java

8 Run it as follows:
java -classpath .;./jsapi.jar;./freetts.jar;./cmu_us_kal.jar HelloWorld

9. Following output came:
All general Mode JSAPI Synthesizers and Voices:
FreeTTS en_US general synthesizer (mode=general, locale=en_US):
kevin
kevin16

Using voice: kevin16

and I hear the voice as well.

and my own test code:

import javax.speech.*;
import javax.speech.synthesis.*;
import java.util.Locale;

public class HelloWorld2 {

public static void main(String args[]) {

try {

// Create a synthesizer for English

Synthesizer synth = Central.createSynthesizer(

new SynthesizerModeDesc(Locale.ENGLISH));



// Get it ready to speak

synth.allocate();

synth.resume();

// Speak the "Hello world" string

synth.speakPlainText("I love Java programming.", null);

// Wait till speaking is done

synth.waitEngineState(Synthesizer.QUEUE_EMPTY);

// Clean up

synth.deallocate();

} catch (Exception e) {

e.printStackTrace();

}

}

}
