I dunno what this is.

javaFlacEncoder.FLACFileWriter is not there :(. Is this a separate wrapper I may have to download?

hi, if I could get a sample main class that translates speech to text?

Hi !

I use your api in my Siri like app : Asilane.
I've modified a little bit your program but sometimes an exception is throwed :
java.lang.NegativeArraySizeException
at com.darkprograms.speech.recognizer.FlacEncoder.convertWaveToFlac(FlacEncoder.java:57)
at com.darkprograms.speech.recognizer.Recognizer.getRecognizedDataForWave(Recognizer.java:70)
at com.darkprograms.speech.recognizer.Recognizer.getRecognizedDataForWave(Recognizer.java:94)
at com.darkprograms.speech.recognizer.Recognizer.getRecognizedDataForWave(Recognizer.java:155)

I'm using the java-speech-api dowloaded this summer.

hey! am new and i been using your libraries to build my own speech system. now i want to implement the passive listening but it seems not work cause it uses the old recognizer (V1). would you help me to repair the code? if you have any solution or option for me it will be great.

thx for your work

Byte[] data = Files.read(mic.getAudioFile());//Saves data into memory.

Which class does this "Files" belong to? I use NetBeans IDE, and it's suggesting me Files.ReadAllBytes (which requires a Path, not a File).

java.io.IOException: Server returned HTTP response code: 403 for URL: http://translate.google.com/translate_a/t?client=thello+world

You should look into this.

Code:

String language = "auto";
Synthesiser synth = new Synthesiser(language);
try {
InputStream is = synth.getMP3Data(output);
AudioStream audioStream = new AudioStream(is);
AudioPlayer.player.start(audioStream);
//TODO Use any Java MP3 Implementation to play back the AudioFile from the InputStream.
}
catch (Exception e) {
// TODO Auto-generated catch block
System.out.println("Error");
e.printStackTrace();
return;
}

hi, if I could get a sample main class that translates speech to text?

https://github.com/gillesdemey/google-speech-v2

note the new endpoint can be invoked directly from a clone of above. You can see that the response is 'chunked encoded' for continuous response. I do not know whether the input side is also chunked . If it is , you can just hook up the mic to an encoder and then write the flac/speechX encoded bytes out to the api in a long running http connection.

I want to know the language support by this API?

Can it support Hindi language or other Indian languages?

Regrettably, my Java skills are rusty and here is my code:

public class SpeechTest {
public static void main(String[] args){
GSpeechDuplex dup = new GSpeechDuplex(AI....Q0); //--Abbreviated API key--
dup.addResponseListener(new GSpeechResponseListener(){// Adds the listener
public void onResponse(GoogleResponse gr){
System.out.println("Google thinks you said: " + gr.getResponse());
System.out.println("with " +
((gr.getConfidence()!=null)?(Double.parseDouble(gr.getConfidence())*100):null)
+ "% confidence.");
System.out.println("Google also thinks that you might have said: "
+ gr.getOtherPossibleResponses());
}
});

    Microphone mic = new Microphone(FLACFileWriter.FLAC);//Instantiate microphone and have 
    // it record FLAC file.

    File file = new File("CRAudioTest.flac");//The File to record the buffer to. 
    //You can also create your own buffer using the getTargetDataLine() method.

    while(true){
        try{
            mic.captureAudioToFile(file);//Begins recording
            Thread.sleep(10000);//Records for 10 seconds
            mic.close();//Stops recording
            //Sends 10 second voice recording to Google
            byte[] data = Files.readAllBytes(mic.getAudioFile().toPath());//Saves data into memory.
                    dup.recognize(data, (int)mic.getAudioFormat().getSampleRate());    
            mic.getAudioFile().delete();//Deletes Buffer file
            //REPEAT
        }
        catch(Exception ex){
            ex.printStackTrace();//Prints an error if something goes wrong.
        }
    }
}

}

Here are my errors:

Exception in thread "main" java.lang.Error: Unresolved compilation problems:
AI....Q0 cannot be resolved to a variable
The method getOtherPossibleResponses() is undefined for the type GoogleResponse
The method getAudioFormat() from the type Microphone is not visible

at SpeechTest.main(SpeechTest.java:12)

Any assistance would be much appreciated.

Thanks,
Shaun

Text to speech queries longer than 100 characters thrown an exception (probably because Google ignores the request). I've implemented a work around text parser in my code that breaks the query into multiple smaller queries, but it would by nice to implement something like this in the synthesiser.getMP3Data(String) method automatically.

Just making a suggestion that you could increase the efficiency of your program by streaming audio directly to GoogleSpeechAPIv2. Below is a working nodejs proof-of-concept. I'm still trying to make a Python variant. And I'm looking forward to trying your project on a RaspberryPi.

var request = require("request");
var rec = require('node-record-lpcm16');
rec.start({
sampleRate : 16000,
verbose : true
}).pipe(request.post({
'url' : 'https://www.google.com/speech-api/v2/recognize?output=json&lang=en-us&key=apikeyhere',
'headers' : {
'Content-Type' : 'audio/l16; rate=16000;'
}
}, exports.parseResult));
}

I try curl on my mac:

curl -v -X POST \
--data-binary @speech.flac \
--user-agent 'Mozilla/5.0 (Macintosh; Intel Mac OS X 10_6_8) AppleWebKit/535.7 (KHTML, like Gecko) Chrome/16.0.912.77 Safari/535.7' \
--header 'Content-Type: audio/x-flac; rate=8000;' \
'https://www.google.com/speech-api/v1/recognize?client=chromium&lang=zh-CN&maxresults=10' 

It never works but return as below:

does anyone have the same problem?

When running the FLAC encoder on a local version of this file: http://buggerluggs.tripod.com/wavs/hello.wav

Do you have that same problem on the same file?

Hey Shadow, this project looks insanely cool! Unfortunately, I can't figure out what the dependency is for all the FLAC-related stuff, as I am being given a bunch of "Can't find this class" errors from Netbeans. If you could tell me (and potentially add it to the README) that would be great!

Thanks for putting cool things like this on gh :)

Hi,

I am trying to send 30 sec of 16000 of wav files by using the flak getRecognizedDataForWave

But google seends back a 500. Do you have any ide what this can be?

Thanks

cool wrapper you built

I am trying to run the helloworld example of this library, but am unable to do so as making requests to google is failing. Following is the error stack-trace:
ERROR: Google cannot be contacted
java.io.FileNotFoundException: https://www.google.com/speech-api/v1/recognize&lang=en-US&maxresults=4

This is failing within the Recognizer.java in the following code
br = new BufferedReader(new InputStreamReader(urlConn.getInputStream(), Charset.forName("UTF-8")));

Is there an alternate way of making this work - like using the V2 of Speech to Text api?

I run the tutorial "hello word" program and got an IOException: Server returned HTTP response code: 500 for URL: https://www.google.com/speech-api/v1/recognize?xjerr=1&client=chromium&lang=en-US&maxresults=4

When following this tutorial that you have written, but slightly modified to use the V2 speech API (GSpeechDuplex) instead of the V1 API shown in the tutorial, I get this error: java.io.FileNotFoundException: AudioTestNow.flac (The requested operation cannot be performed on a file with a user-mapped section open)
No line is given that is inside my code. However, it still gets a response from the server (and is correct).

The modified code from the tutorial:

GSpeechDuplex dup = new GSpeechDuplex(API_KEY);
dup.addResponseListener((GoogleResponse gr) ->
{
    displayResponse(gr);
});
dup.recognize(mic.getAudioFile(), (int)mic.getAudioFormat().getSampleRate());

In case you want it, here's the full log:

Thanks for your great API. It works perfectly!
But! If I set a wrong API key or no API key there is an exception thrown in the http thread...
Exception in thread "Downstream Thread"
java.lang.NullPointerException

Can you enable a possibility to catch it via callback for example?

Whenever I try to run mic.captureAudioToFile, it gives me a javax.sound.sampled.LineUnavailableException: line with format PCM_SIGNED 8000.0 Hz, 16 bit, mono, 2 bytes/frame, little-endian not supported error

Here's my code - https://gist.github.com/MasterEjay/11126602

Hi,

Since it has been suggested (sorry for being off-topic the other day), I'm opening my own issue about a connectivity problem I'm encountering with Google servers.

Here is what I'm woking with:

• Current version of J.A.R.V.I.S
• Hello World test class I got from the Wiki section of this same repo

I've mostly tried step-by-step debugging on the "rawRequest" method in Recognizer.java, to see if it came from the request building part (especially when encoding FLAC data), still no clue.

1. The built request URL is the following (nothing fancy here, I just kept default parameters) :
   https://www.google.com/speech-api/v1/recognize?xjerr=1&client=chromium&lang=en-US&maxresults=4
2. I can only guess that up to when outputStream has read fileInput data (and it is properly encoded) things are going great (but i'm not familiar with dealing with streams and HTTP requests in Java). Plus, I can see data written in outputStream.buf.
3. The part where things get wrong must be around when the BufferedReader getting the InputStream, because then I get... a null br. Also, when the response string reads this br, it becomes null.

I hope this info can help solving my case, if you need to know more about a particular point, please ask me!

As I've been told recently, even if Google has in the meantime (silently) released a v2 of its speech API, the "old" one should still work, so I'm really clueless now, after trying a few hours to understand why my attempts keep failing.

Any hints or help would be greatly appreciated :)

Hi,

here is my code:

public static void main(String[] args){
        GSpeechDuplex dup = new GSpeechDuplex("AS***********************Fto");//Instantiate the API
        dup.addResponseListener(new GSpeechResponseListener(){// Adds the listener
            public void onResponse(GoogleResponse gr){
                System.out.println("Google thinks you said: " + gr.getResponse());
                System.out.println("with " + 
                ((gr.getConfidence()!=null)?(Double.parseDouble(gr.getConfidence())*100):null) 
                    + "% confidence.");
                System.out.println("Google also thinks that you might have said:" 
                        + gr.getOtherPossibleResponses());
            }
        });
        Microphone mic = new Microphone(AudioFileFormat.Type.WAVE);//Instantiate microphone and have 
        // it record FLAC file.
        File file = new File("CRAudioTest.wav");//The File to record the buffer to. 
        //You can also create your own buffer using the getTargetDataLine() method.
        while(true){
            try{
                mic.captureAudioToFile(file);//Begins recording
                Thread.sleep(5000);//Records for 10 seconds
                mic.close();//Stops recording
                //Sends 10 second voice recording to Google
                Path path = Paths.get("CRAudiotest.wav");
                byte[] data = Files.readAllBytes(path);//Saves data into memory.
                        dup.recognize(data, (int)mic.getAudioFormat().getSampleRate());
                mic.getAudioFile().delete();//Deletes Buffer file
                //REPEAT
            }
            catch(Exception ex){
                ex.printStackTrace();//Prints an error if something goes wrong.
            }
        }
    }

I replaced the Flac with the wav files, because it threw me an error that FLACFileWriter wasn't there.
Basically what the log says:
Starting to write
IO WRITE DONE
Finished write on down stream...

And this goes on in a loop.

I also tried another method:

private static void ambientListening() throws Exception{

        String filename = "tarunaudio.wav";//Your Desired FileName
        MicrophoneAnalyzer mic = new MicrophoneAnalyzer(AudioFileFormat.Type.WAVE);
        mic.open();
        System.out.println("start talking.");
        mic.captureAudioToFile(filename);
        Thread.sleep(3000);
        mic.close();
        System.out.println("stop talking");
        FlacEncoder encoder = new FlacEncoder();
        encoder.convertWaveToFlac(filename, "newfilename.flac");

        try {
        RecognizerChunked rec = new RecognizerChunked("************************************"); //this is the api key I blurred out
        GoogleResponse googleResponse = rec.getRecognizedDataForFlac("newfilename.flac", 8000);
        System.out.println(googleResponse.getResponse());
        } catch (Exception e) {
            e.printStackTrace();
        }


    }

The code above gives me the error that getRecognizedDataForFlac should return in GoogleResponse, but in the method it won't return anything.

(I'm quite new to Java and OOP)

This great project!, I wonder if it has support for recognition in Spanish. Thank you

Hi, I can't seem to find the main method for the API?

Would you mind putting down a hello world example? Thanks!

I am trying to create an application that employs speech to text recognition. In order to better understand the Shadow API, I ran the sample application. The application runs successfully. But what I found was that upon running, it successfully converts speech to text the first time, but subsequent attempts to convert speech to text result in java.net.SocketException . This happens each time I run the application.

The exception gets thrown when the method getOutputStream() is called in Recognizer.java.

On searching the internet I found that one of the causes for this kind of behavior can be the antivirus program. So I disabled my antivirus. And on disabling the antivirus, the application works perfectly. It does not throw java.net.SocketException at all.

So one solution for this issue can be disabling of antivirus.

But I cannot expect the user of my application to disable his/her antivirus program to be able to use my application. And even after a lot of research I am not able to find any solution apart from this.

Could anyone guide me as to what can be done to not get the exception, apart from disabling the antivirus. Any help would be highly appreciated.

It appears as though the V1 Speech Recognition API has been discontinued (the URL is generating 400 error). In the meantime, please use the V2 Duplex and chunked APIs instead. We are working on solving this issue ASAP.

Hello,

unfortunately I can't get your api to work =(

https://www.google.com/speech-api/full-duplex/v2/ only gives me a 404, as well as the GSpeechDuplex class:

Hi,
I'm working on a plugin using your old GUI adapted for my need. In the last changes the class AePlayWave.java is no more available. Is it possible to include it again on the repo?
Thanks
Mauro

Good day!
Is it possible to use multiple microphones in the library?
How do I know which device is produced capture sound?

The-Shadow could you please delete this Issue?

Hi,
I found that Google only provide confidence score for first hypothesis, I would like to find the confidence score for second, third ... hypotheses.
Thank you.

    GoogleResponse response = recognizer.getRecognizedDataForFlac(file, maxNumOfResponses);

This is an invalid line because the class recognizer.getRecognizedDataForFlac doesn't exist.

Netbeans IDE 7.3, JDK 7.

Hello guy!
I could compile the example that you provided. I have no problems with de synthesiser, but on the other hand, the app don't recognize the microphone of my notebook.

Do you have an idea about the problem??
I compiled it on Eclipse (maybe here is the problem), in Windows 7.
Thanks!!!

Hey Shadow, this project looks insanely cool! Unfortunately, I can't figure out what the dependency is for all the FLAC-related stuff, as I am being given a bunch of "Can't find this class" errors from Netbeans. If you could tell me (and potentially add it to the README) that would be great!

Thanks for putting cool things like this on gh :)

                    resp.setText(parsedtext);
                }

                @Override
                public void onResponse(GoogleResponse gr) {
                    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
                }
            });
            micra=new Microphone(FLACFileWriter.FLAC);
            audiofil=new File("AudioTest.flac");
            while(true){
                try{
                    micra.captureAudioToFile(audiofil);
                    Thread.sleep(5000);
                    micra.close();
                    byte[] data=Files.readAllBytes(micra.getAudioFile().toPath());
                    duplo.recognize(data, (int)micra.getAudioFormat().getSampleRate());
                    micra.getAudioFile().delete();
                }
                catch (Exception ex){
                    ex.printStackTrace();
                }
            }
        }
    });
   MicInputThread.start();
}                                 

So why is it behaving like that?

I wrote this simple code to test your lib:

package net.datao.stt;

import com.darkprograms.speech.microphone.Microphone;
import com.darkprograms.speech.recognizer.Recognizer;

import javax.sound.sampled.AudioFileFormat;
import javax.swing.*;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;

/**

  */
  public class DoItAll extends JFrame {
  JButton stop = new JButton("Stop");
  JButton run = new JButton("Run");
  JButton process = new JButton("Process");
  Microphone microphone = new Microphone(AudioFileFormat.Type.WAVE);
  Recognizer recognizer = new Recognizer();
  String audioFile = "c:/temp/toto.wav";

  public DoItAll(){
  stop.addActionListener(new ActionListener() {
  public void actionPerformed(ActionEvent e) {
  microphone.close();
  }
  });
  run.addActionListener(new ActionListener() {
  public void actionPerformed(ActionEvent e) {
  try {

              microphone.captureAudioToFile(audioFile);
          } catch (Exception e1) {
              e1.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
              JOptionPane.showMessageDialog(null, e1.getMessage());
          }
      }
  });
  process.addActionListener(new ActionListener() {
      public void actionPerformed(ActionEvent e) {
          String response = "error";
          try {
              response = recognizer.getRecognizedDataForWave(audioFile).getResponse();
          } catch (Exception e1) {
              e1.printStackTrace();  //To change body of catch statement use File | Settings | File Templates.
              response = e1.getMessage();
          }
          JOptionPane.showMessageDialog(null, response);
      }
  });
  getContentPane().setLayout(new BoxLayout(getContentPane(), BoxLayout.X_AXIS));
  getContentPane().add(run);        
  getContentPane().add(stop);
  getContentPane().add(process);
  setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
  pack();
  show();
  

  }

  public static void main(String[] args) {
  new DoItAll();
  }

}

It show a JFrame, you click "Run", you talk in the micro, you stop talking, you click "Stop" and then click "Process". And then a JOptionPane shows the google response.
Easy.
But I get this rawResponse from Google:
{"status":5,"id":"5ea8848cad8489a332c589dcfaa14af4-1","hypotheses":[]}
and my code ends with an exception.

Did I miss something?
Or did Google change something that breaks java-speech-api ?

It would be cool to have this available via Maven Central Repository:

Hi, thank you for your work. It works well. But I would like to use the streaming audio with Dpulex API. I do not see any class called MicDuplex.java in your project. Where can I get it ?

Thank you

I'm very sorry, I'm completely new to programming and am currently taking a class in Java, I'm just trying to get the Hello World example running but I'm having a problem on this line:

Byte[] data = Files.read(mic.getAudioFile());//Saves data into memory.
dup.recognize(data, (int)mic.getAudioFormat().getSampleRate());

getting the following error:
Exception in thread "main" java.lang.Error: Unresolved compilation problems:
The method read(InputStream, int) in the type Files is not applicable for the arguments (File)
The method recognize(File, int) in the type GSpeechDuplex is not applicable for the arguments (Byte[], int)

at com.darkprograms.speech.Main.main(Main.java:43)]

Please let me know what I'm doing wrong here, I'm pretty sure I've set everything up correctly

Hello!

Thank you for this api.

One question:
How can I stop captureAudioToFile?

Would it be possible to create a new GitHub release containing the latest working source code?
I seem to be unable to build the repository from the current source code, as I can not resolve the project's dependencies.
Perhaps it might be worth looking into setting up Apache Maven with this project, in which case I could definitely help setup dependency management.

Thankyou,

Do note that no other application is using the microphone right now.

Here is my code:

 Thread MicInputThread=new Thread(new Runnable(){
        public void run(){
            duplo.addResponseListener(new GSpeechResponseListener(){
                public void OnResponse(GoogleResponse googres){
                    String parsedtext=googres.getResponse();
                    System.out.println(parsedtext);
                }

                @Override
                public void onResponse(GoogleResponse gr) {
                    throw new UnsupportedOperationException("Not supported yet."); //To change body of generated methods, choose Tools | Templates.
                }
            });
            micra=new Microphone(FLACFileWriter.FLAC);
            audiofil=new File("AudioTest.flac");
            while(true){
                try{
                    micra.captureAudioToFile(audiofil);
                    Thread.sleep(5000);
                    micra.close();
                    byte[] data=Files.readAllBytes(micra.getAudioFile().toPath());
                    duplo.recognize(data, (int)micra.getAudioFormat().getSampleRate());
                    micra.getAudioFile().delete();
                }
                catch (Exception ex){
                    ex.printStackTrace();
                }
            }
        }
    });
   MicInputThread.start();
}                                        

Is it possible that this line of code byte[] data=Files.readAllBytes(micra.getAudioFile().toPath()); may be the culprit?

RecognizerChunked's parseResponse function paser fellow response

{"result":[{"alternative":[{"transcript":"This is a apple","confidence":0.97342438},{"transcript":"This is a apple"},{"transcript":"This is a apple"}],"final":true}],"result_index":0}

Making 0.97342438 as element of otherPossibleResponses ArrayList, result as

Google thinks you said: This is a apple
with 97.342438% confidence.
Google also thinks that you might have said:[0.97342438, This is a apple, This is a apple]

I would like to adapt java-json to parse raw response

    /**
     * Parses the response into a Google Response
     * @param rawResponse The raw String you want to parse
     * @param gr The GoogleResponse you want to parse into ti.
     */
    private void parseResponse(String rawResponse, GoogleResponse gr){
        if(rawResponse == null || !rawResponse.contains("\"result\"")){ return; }

        JSONObject object = new JSONObject(rawResponse);
        JSONObject result = object.getJSONArray("result").getJSONObject(0);
        JSONArray ASRHypotheses = result.getJSONArray("alternative");
        String response = "";
        String confidence = "";
        if (ASRHypotheses.length() == 1) {
            //  Google is 100% confident in it's translation
            response = ASRHypotheses.getJSONObject(0).getString("transcript");
            if (ASRHypotheses.getJSONObject(0).has("confidence")) {
                confidence = String.valueOf(ASRHypotheses.getJSONObject(0).getDouble("confidence"));
            }
            else {
                confidence = String.valueOf(1d);
            }
        }
        else {
            String otherResponse;
            for (int i = 0; i < ASRHypotheses.length(); i++) {
                if (i == 0) {
                    response = ASRHypotheses.getJSONObject(i).getString("transcript");
                    confidence = String.valueOf(ASRHypotheses.getJSONObject(i).getDouble("confidence"));
                } else {
                    System.out.println(ASRHypotheses.getJSONObject(i));
                    otherResponse = ASRHypotheses.getJSONObject(i).getString("transcript");
                    gr.getOtherPossibleResponses().add(otherResponse);
                }
            }
        }
        gr.setResponse(response);
        gr.setConfidence(confidence);
    }
