android 語音辨識技術

偶然在網上看到。於是照著網上的例子寫了一個例子。很簡單，就是實現語音辨識。後來的TTS沒有做。

直接貼代碼

View Code

/** * 語音辨識 *  * @author sy *  */public class SpeakToActivity extends Activity{    /** Called when the activity is first created. */    private Button mSpeakButton;    @Override    public void onCreate(Bundle savedInstanceState)    {        super.onCreate(savedInstanceState);        setContentView(R.layout.main);        mSpeakButton = (Button) findViewById(R.id.openSpeak);        mSpeakButton.setOnClickListener(new ButtonOnClick());    }    /**     * button點擊事件     *      * @author sy     *      */    class ButtonOnClick implements OnClickListener    {        @Override        public void onClick(View v)        {            try            {                // TODO Auto-generated method stub                Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH); // 使用Intent開始語音辨識                // //語言模式和自由模式的語音辨識                intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL, RecognizerIntent.LANGUAGE_MODEL_WEB_SEARCH);                intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "開始語音");// 只是提示音開始                startActivityForResult(intent, 10);// 對應onActivityResult方法中得requestCode            } catch (Exception e)            {                e.printStackTrace();                // 如果找不到語音裝置則提示                Toast.makeText(SpeakToActivity.this, "找不到語音裝置", Toast.LENGTH_LONG).show();            }        }    }    /**     * activity回呼函數，和startActivityForResult對應     *      * @author sy     */    @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data)    {        // TODO Auto-generated method stub        super.onActivityResult(requestCode, resultCode, data);        if (requestCode == 10 && resultCode == RESULT_OK)        {            ArrayList<String> results = data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS); // 擷取結果集            String resultString = "";            // 如果使用這段注釋的代碼，google則會返回5個類似於你發音的詞            // for (int i = 0; i < results.size(); i++)            // {            // resultString+=results.get(i);            // }            resultString += results.get(0);// 我預設選擇了第一個            Toast.makeText(SpeakToActivity.this, resultString, Toast.LENGTH_LONG).show();        }    }}
