Android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：
/**
* 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();
showDialog();
}
}
private void showDialog() {
