(Android實戰)語音辨識，根據語音，執行對應操作

在iphone4s 發布後，siri語音功能成為了一時成為了熱點，這幾天想寫個類似於siri類似功能的android應用，下面就是關鍵的兩個技術點

 1 語音辨識：

private static final int VOICE_RECOGNITION_REQUEST_CODE = 1234;

/**
     * 開啟語音辨識對話表單
*/
private void startVoiceRecognitionActivity() {
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
                RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT,
                "Speech recognition demo");
        startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
    }

/**
     * 處理語音對話方塊返回的識別資訊.
*/
    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE
                && resultCode == RESULT_OK) {
// 擷取反饋的語音辨識數組，並按照匹配度反饋

            ArrayList<String> matches = data
                    .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);


        }

    }

2 根據指令，進行打電話，發簡訊，開啟網站操作：

if (voicekey.type == 1) { //電話
                
                txtview_secretary.setText("正在為你接通電話...");
                Thread.sleep(1000);
                Intent intent = new Intent(Intent.ACTION_CALL);
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                intent.setData(Uri.parse("tel://" + voicekey.data));
                startActivity(intent);
            } else if(voicekey.type == 2){//簡訊
                
                txtview_secretary.setText("正在為你發簡訊...");
                Thread.sleep(1000);
                Intent intent = new Intent(Intent.ACTION_SENDTO,Uri.parse("sms:"+voicekey.data));
                startActivity(intent);
            }
else if(voicekey.type == 3) //網址
            {
// open kit explore ,navigate to net bank,close App
                txtview_secretary.setText("正在為你開啟網站...");
                Thread.sleep(1000);
                Uri uri = Uri.parse(voicekey.data);
                Intent intent = new Intent(Intent.ACTION_VIEW, uri);
                startActivity(intent);
            }
