语音转文本 API 其他语言安卓

Question

我开发了安卓应用程序，可以识别普通话语音，然后生成文本。但是我找不到该怎么做。有人可以给我其他语言（普通话、法语等）的语音识别示例代码吗？

public class MainActivity extends Activity {
private TextView txtSpeechInput;
private ImageButton btnSpeak;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    txtSpeechInput = (TextView) findViewById(R.id.txtSpeechInput);
    btnSpeak = (ImageButton) findViewById(R.id.btnSpeak);
    // hide the action bar
    getActionBar().hide();
    btnSpeak.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            listen();
        }
    });
}

private static int SR_CODE = 123;
/**
 * Initializes the speech recognizer and starts listening to the user input
 */
private void listen()  {
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        //Specify language
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.SIMPLIFIED_CHINESE);
        // Specify language model
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        // Specify how many results to receive
        intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);
        // Start listening
        startActivityForResult(intent, SR_CODE);
    }
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    if (requestCode == SR_CODE && resultCode == RESULT_OK) {
        if (data != null) {
            // Retrieves the best list SR result
            ArrayList<String> nBestList = data
                    .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
            String bestResult = nBestList.get(0);
            Toast.makeText(getApplicationContext(), bestResult,
                    Toast.LENGTH_LONG).show();
        } else {
            // Reports error in recognition error in log
            Log.e("Log", "Recognition was not successful");
        }
    }
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}
}

Answer 1

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "zh");
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, "zh");
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_PREFERENCE, "zh");
intent.putExtra(RecognizerIntent.EXTRA_SUPPORTED_LANGUAGES, "zh");
intent.putExtra(RecognizerIntent.EXTRA_ONLY_RETURN_LANGUAGE_PREFERENCE,"zh");
intent.putExtra(RecognizerIntent.EXTRA_CALLING_PACKAGE, "zh");
intent.putExtra(RecognizerIntent.EXTRA_RESULTS, "zh");

Answer 2

调用识别器时可以设置RecognizerIntent.EXTRA_LANGUAGE。

因此，简体中文的示例将是：

private static int SR_CODE = 123;

/**
     * Initializes the speech recognizer and starts listening to the user input
     */
    private void listen()  {
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        //Specify language
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, Locale.SIMPLIFIED_CHINESE)
        // Specify language model
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        // Specify how many results to receive
        intent.putExtra(RecognizerIntent.EXTRA_MAX_RESULTS, 5);
        // Start listening
        startActivityForResult(intent, SR_CODE);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        if (requestCode == SR_CODE && resultCode == RESULT_OK)  {
                if(data!=null) {
                //Retrieves the best list SR result
                ArrayList<String> nBestList = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
               String bestResult = nBestList.get(0);
               Toast.makeText(getApplicationContext(), bestResult, Toast.LENGTH_LONG).show;              
            }else {         
                //Reports error in recognition error in log
                Log.e(LOGTAG, "Recognition was not successful");
            }
    }
