Question

我们正在使用pocketsphinx来帮助我们将.wav文件转换为文本文件。我们不知道为什么它会给我们一个奇怪的输出，因为它在转换后只给我们<s>和</s>。我们正在使用cmusphinx社区提供的默认字典，语言模型和声学模型。

以下是我们用于转换的代码：

package com.example.saling_wika.saling_wika;


import android.app.Activity;
import android.net.Uri;
import android.os.AsyncTask;
import android.os.Bundle;
import android.os.Environment;
import android.util.Log;
import android.widget.Toast;


import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import java.io.InputStream;
import java.net.MalformedURLException;
import java.net.URL;
import java.nio.ByteBuffer;
import java.nio.ByteOrder;

import static junit.framework.Assert.fail;





public class ConversionModule extends Activity {
    static {
        System.loadLibrary("pocketsphinx_jni");
    }
    Config c;
    Decoder ps;
    FileInputStream stream;

    @Override
    public void onCreate(Bundle state) {
        super.onCreate(state);
        setContentView(R.layout.main);

        c = Decoder.defaultConfig();

    /*Configuring decoder object*/
        c.setString("-hmm", new File(Environment.getExternalStorageDirectory() + "/Android/data/com.example.saling_wika.saling_wika/files/sync", "en-us-ptm").getPath());
        c.setString("-dict", new File(Environment.getExternalStorageDirectory() + "/Android/data/com.example.saling_wika.saling_wika/files/sync", "cmudict-en-us.dict").getPath());
        c.setString("-lm", new File(Environment.getExternalStorageDirectory() + "/Android/data/com.example.saling_wika.saling_wika/files/sync", "weather.dmp").getPath());
        c.setBoolean("-allphone_ci", true);


        ps = new Decoder(c);


        try {
            final File file = new File(AudioToConvert.pathko);
            Uri uri = Uri.fromFile(file);
            File auxFile = new File(uri.getPath());
            stream = new FileInputStream(auxFile);


        } catch (FileNotFoundException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }




        ps.startUtt();
        byte[] b = new byte[4096];
        try {
            int nbytes;
            while ((nbytes = stream.read(b)) >= 0) {
                ByteBuffer bb = ByteBuffer.wrap(b, 0, nbytes);
                short[] s = new short[nbytes / 2];
                bb.asShortBuffer().get(s);
                ps.processRaw(s, nbytes / 2, false, false);
            }
        } catch (IOException e) {

        }
        ps.endUtt();
        //  System.out.println(ps.hyp().getHypstr());
        Toast.makeText(getApplicationContext(), ps.hyp().getHypstr(), Toast.LENGTH_LONG).show();
        for (Segment seg : ps.seg()) {
            //  System.out.println(seg.getWord());
            Toast.makeText(getApplicationContext(),seg.getWord(), Toast.LENGTH_LONG).show();
        }
        ;


    }
}

Answer 1

正如CMUSphinx forum所述，您有多个问题：

您需要按照Give a file as input to Pocketsphinx on Android

bb.order(ByteOrder.LITTLE_ENDIAN);

您的输入文件应为PCM格式16khz 16位单声道。如果您想提交一些编码文件，您需要先将其解码为原始数据。

将<s>和</s>作为android pocketsphinx的输出
