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() 如果大家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了 貼出代碼：  

/**

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();  
        showDialog();  
    }

        ArrayList<String> results = data  
                .getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS);  
  
        if (results.size() > 0) {  
            voiceView.setText(results.get(0));  
        } else {  
            Utils.getInstance().showTextToast("檢測失敗，請重新點擊識別!", context);  
        }  
    }  
}
