Question

我正在寻找一种用于将印度语（如印地语或泰米尔语）语言转换为文本的Android API？

如果没有API支持，我该如何实现？

Answer 1

将intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "hin-IND")用于Hindi语言。

试试这个：

import java.util.ArrayList;
import java.util.Locale;

import android.app.Activity;
import android.content.ActivityNotFoundException;
import android.content.Intent;
import android.os.Bundle;
import android.speech.RecognizerIntent;
import android.view.Menu;
import android.view.View;
import android.widget.ImageButton;
import android.widget.TextView;
import android.widget.Toast;

public class MainActivity extends Activity {

    private TextView txtSpeechInput;
    private ImageButton btnSpeak;
    private final int REQ_CODE_SPEECH_INPUT = 100;

    @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);

        btnSpeak.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                promptSpeechInput();
            }
        });

    }

    /**
     * Showing google speech input dialog
     * */
    private void promptSpeechInput() {
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "hin-IND");

        try {
            startActivityForResult(intent, REQ_CODE_SPEECH_INPUT);
        } catch (ActivityNotFoundException a) {
            Toast.makeText(getApplicationContext(),
                    getString(R.string.speech_not_supported),
                    Toast.LENGTH_SHORT).show();
        }
    }

    /**
     * Receiving speech input
     * */
    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);

        switch (requestCode) {
        case REQ_CODE_SPEECH_INPUT: {
            if (resultCode == RESULT_OK && null != data) {

                ArrayList<String> result = data
                        .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);
                txtSpeechInput.setText(result.get(0));
            }
            break;
        }

        }
    }     
}

这是一个很好的tutorial。希望这会有所帮助〜

Answer 2

intent.putExtra（RecognizerIntent.EXTRA_LANGUAGE，“ hin-IND”）;

更改为

intent.putExtra（RecognizerIntent.EXTRA_LANGUAGE，“ hi-IN”）;

Answer 3

更新的工作方法（2020年）

感谢this的答案，对于印度语言，请尝试使用以下格式：
<lang-code>_IN

示例：-

recognizerIntent.putExtra(RecognizerIntent.EXTRA_LANGUAGE,"hi_IN")

使用EXTRA_LANGUAGE而不是EXTRA_LANGUAGE_PREFERENCE对我有用。

演讲文字Android api为印度语言
