Text to speech

[jaspreet manchinda]

for my college project i am making a text to speech n speech to test software just needed help that how to make my synthesizer read a documents in my hard disk


NEED HELP!!! ASAP

[Joanne Neal]

The first thing you should do is read KeepItDown and EaseUp.
Then you can try the Java I/O tutorial

[jaspreet manchinda]

thank you @Joanne Neal i will definitely KeepItDown and EaseUp thank you for your time appreciated

[jaspreet manchinda]

i want to make it read all the notepad files and word document and any other text file on my disk so how can i make synthesizer make read all the files can you please help me with bit of code

import javax.speech.*;
import javax.speech.synthesis.*;
import java.util.Locale;
import javax.speech.synthesis.Voice.*;
public class HelloWorld {
	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("Hello world", null);
			

			// Wait till speaking is done
			synth.waitEngineState(Synthesizer.QUEUE_EMPTY);

			// Clean up
			synth.deallocate();
		} catch (Exception e) {
			e.printStackTrace ();
		}
	}
}

The File class has methods for listing all the files in a directory. The tutorial I linked to above will show you how to read plain text files. Word documents are a little more difficult as they are not plain text. I've never used it but the POI library is often mentioned on these forums when people ask how to read various Microsoft format files such as Word and Excel. The search function on here or Google should be able to provide you with more information about it.

[jaspreet manchinda]

can you help me with a small example

[Joanne Neal]

The tutorial contains plenty of examples. Which bit are you having a problem with ? Show us what you've tried and how the results differ from what you were expecting.

[jaspreet manchinda]

SIR,
I appreciate your time and reply , actually I'am not all that good in coding I'am new to it i don't know how to use FileInputStream along with the synthesizer part of speech .It would be a great help if you can explain with small snippet of code that how can i use synthesizer with FileInputStream

[jaspreet manchinda]

it worked thank you so much but still don't know how to read word documents and notepad files

[Stephan van Hulst]

Do you know how to work with classes, instances and methods? If not, go to the Java tutorials.

If you do, then you need a Reader instance to read words. First you need an instance of FileInputStream. Then create an instance of InputStreamReader using that, and finally create an instance of BufferedReader, and pass the InputStreamReader to it.

Now, using this BufferedReader you can easily read lines from the file.

yes sir i did that and its working but dont know how to read microsoft format file and mail box

The Apache POI library can extract text from various MS Office file formats and Outlook MSG files.

Notepad files are plain text; what particular problem are you facing in reading those?

[jaspreet manchinda]

i.am abel to read notepad files but exactly dont know how to read word files and emails

[Joanne Neal]

Have you looked at POI ? What specific problems are you having with it ?

Here's what I would suggest: You have a limited amount of time to complete this project. It may be that you don't have enough time to deal with plain text and Word documents and e-mails and whatever else you have in mind, so you might find that you end up with an incomplete project which can't handle any of those things properly. So start with plain text ("Notepad") documents and produce something which can read one of those and convert it to spoken form.

At that point you have a project which you could hand in as a finished project, in the worst case. Maybe not very impressive and not what you hoped for, but still a working piece of code. And then if you have more time, you could work on those other formats. Notice that by choosing plain text first, your task then becomes how to convert a Word document (or an e-mail or whatever) to plain text, since you already know how to handle plain text.

need one more help wen i am trying to change the locale from english to any other language its hiving a java.lang.NullPointerException

[Joanne Neal]

The stack trace of the exception will tell you what line of your code it happens on. Use a debugger or put in some print statements to find out which variable is null on that line.

[jaspreet manchinda]

Im not getting that can you please help me with the above code to change the locale i tried japan but its not working

[Joanne Neal]

Post the full stack trace of the exception you get. That will include a line number - tell us which line in your posted code that refers to.

[jaspreet manchinda]

java.lang.NullPointerException
at HelloWorld.main(HelloWorld.java:20)

import java.io.*;

public class HelloWorld 
{
	public static void main(String args[]) 
		{
			try 
				{
			
				

					// Create a synthesizer for English
	
  					Synthesizer synth = Central.createSynthesizer(
                        		new SynthesizerModeDesc(Locale.JAPAN));
					
			

					// Get it ready to speak
					synth.allocate();
					synth.resume();
	
					

				
					FileInputStream fstream = new FileInputStream("TestFile.txt");
  					DataInputStream in = new DataInputStream(fstream);
  					BufferedReader br = new BufferedReader(new InputStreamReader(fstream));
  					String strLine;
			
				while ((strLine = br.readLine()) != null)   
				{
  				
  				synth.speakPlainText(strLine,null);
				}
			

					// Wait till speaking is done
					synth.waitEngineState(Synthesizer.QUEUE_EMPTY);
	
					// Clean up
					synth.deallocate();
				} 
			catch (Exception e) 
				{
					e.printStackTrace();
				}
		}
}

[Tim Moores]

So "synth" is null - you should read the javadocs of all the methods being used in "Central.createSynthesizer(new SynthesizerModeDesc(Locale.JAPAN))" under which circumstances that can happen.

[Joanne Neal]

Okay. So it's probable that synth on line 20 is null. To confirm this put

System.out.println("synth is null: " + (synth == null));

before that line and run your program again.
Assuming it is null, you then need to look at the documentation for the Central.createSynthesizer method to see what can cause it to return null.

[jaspreet manchinda]

its returning true

[Joanne Neal]

jaspreet manchinda wrote:its returning true

Okay. So my supposition was correct. So now you

need to look at the documentation for the Central.createSynthesizer method to see what can cause it to return null.

[jaspreet manchinda]

I'm not getting it but i guess Central.createSynthesizer returns null if it cannot find a suitable synthesizer
but what should i do

[Tim Moores]

Have you installed any synthesizer? If memory serves -and it might not- then the JavaSpeech API does not come with any synthesizers, maybe English but certainly not Japanese; you'd need to get them elsewhere, like from the FreeTTS project.

[jaspreet manchinda]

i tried doing that i downloaded Japanese but it still aint working and i am doin ths using cloudgarden jsapi implementation

[jaspreet manchinda]

ranchers please help

What is the Error Message or Exception you are getting this time?

[jaspreet manchinda]

vishal i am getting the same error that i mentioned earlier

[Vishal Hegde]

Deja VU

Just try this out let me know whether this works or not?

Synthesizer synth = Central.createSynthesizer(
	new SynthesizerModeDesc(
	null, // engine name
	"general", // mode name
	Locale.US, // locale
	null, // running
	null) // voice
	);

[jaspreet manchinda]

vishal this is not the case with me
when we pass null value to synthesizer it uses default locale that is english
Central.createSynthesizer(new SynthesizerModeDesc(Locale.ENGLISH))
is same as Central.createSynthesizer(new SynthesizerModeDesc(null))
but my issue is when i trie to change it to Central.createSynthesizer(new SynthesizerModeDesc(Locale.JAPAN)) or any other language it gives java.lang.NullPointerException

[Tim Moores]

How did you install the Japanese synthesizer? Which instructions did you follow to do that?

[jaspreet manchinda]

i googled it n downloaded it from some site i forgot to bookmark it from there i downloaded the Japanese locale


can anyone tell me how to save text file in different language i used Unicode instead of ANSI is there any other way to save it

[Tim Moores]

jaspreet manchinda wrote:i googled it n downloaded it from some site

OK. What I meant by the question is: are you certain that you did it correctly? It sounds as if it may not be installed.

[jaspreet manchinda]

yes Tim pretty much i am certain bout it

[Vishal Hegde]

Have you tried this mode

RecognizerModeDesc desc = new RecognizerModeDesc(Locale.JAPAN, Boolean.TRUE);

Just try out this Click Here

[jaspreet manchinda]

First thing vishal here we are talkin about text to speech and RecognizerModeDesc is used in speech to text method and it takes boolean to cheack weather the dictation is supported or not. Synthesizer does not take any boolean
