Android 調用谷歌語音識別

調用谷歌語音識別其實很簡單，直接利用 intent 跳轉到手機裡面的谷歌搜索

代碼也很簡單，直接調用方法 startVoiceRecognitionActivity()

如果大傢手機裡面沒有谷歌搜索，這裡會彈出一個下載框給我們選擇下載

識別完成後，得到result List數組,裡面有很多識別結果，我們獲取第一個就可以瞭

貼出代碼：

/** 
 * 調用方法

private void startVoiceRecognitionActivity() {  
    try {  
        // 通過Intent傳遞語音識別的模式，開啟語音  
        Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);  
        // 語言模式和自由模式的語音識別  
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,  
                RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);  
        // 提示語音開始  
        intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "開始語音");  
        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "zh-HK");  
        // 開始語音識別  
        startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);  
    } catch (Exception e) {  
        e.printStackTrace();
