Android(安卓)调用谷歌语音识别

調用谷歌语音识别其实很简单，直接利用 intent 跳转到手机里面的谷歌搜索

代码也很简单，直接调用方法 startVoiceRecognitionActivity()

如果大家手机里面没有谷歌搜索，这里会弹出一个下载框给我们选择下载

识别完成后，得到result List数组,里面有很多识别结果，我们获取第一个就可以了

贴出代码：

[java] view plain copy

/**
* 調用方法
*/
private void startVoiceRecognitionActivity() {
try {
// 通过Intent传递语音识别的模式，开启语音
Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);
// 语言模式和自由模式的语音识别
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,
RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);
// 提示语音开始
intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "开始语音");
intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE, "zh-HK");
// 开始语音识别
startActivityForResult(intent, VOICE_RECOGNITION_REQUEST_CODE);
} catch (Exception e) {
e.printStackTrace();
showDialog();
}
}
private void showDialog() {
AlertDialog.Builder builder = new Builder(MainActivity.this);
builder.setMessage(R.string.dialog_content);
builder.setTitle(R.string.dialog_title);
builder.setNegativeButton(R.string.download,
new android.content.DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
Uri uri = Uri.parse(getApplication().getString(R.string.voice_url));
Intent it = new Intent(Intent.ACTION_VIEW, uri);
startActivity(it);
}
});
builder.setPositiveButton(R.string.cancel,
new android.content.DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();
}
});
builder.create().show();
}
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == VOICE_RECOGNITION_REQUEST_CODE
&& resultCode == RESULT_OK) {
ArrayList 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);
}
}
}
