Android中如何添加语音识别功能?详细步骤和代码?

android.speech.RecognizerIntent这个包里。前提是你的手机支持此功能。

开启操作:

Intent

intent

newIntent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);//开启语音识别功能。

intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,

RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);

//设置语言类型。

intent.putExtra(RecognizerIntent.EXTRA_PROMPT,

"请说话，我识别");

startActivityForResult(intent,REQUEST_CODE);

在onActivityResult()里用:

data.getStringArrayListExtra(RecognizerIntent.EXTRA_RESULTS)取得google云端反馈的数据即可。

如何在android平台上实现语音识别

语音识别，借助于云端技术可以识别用户的语音输入，包括语音控制等技术，下面我们将利用Google 提供的Api 实现这一功能。

功能点为：通过用户语音将用户输入的语音识别出来，并打印在列表上。

功能界面如下：

用户通过点击speak按钮显示界面：

用户说完话后，将提交到云端搜索

在云端搜索完成后，返回打印数据：

android模拟器如何使用语音识别

程序读取一个事先的录音文件，然后将其数据导入语音识别程序中进行识别，识别结果可通过控件显示出来

Android 上的语音识别是怎么实现

如果你想自己写引擎，我不太清楚，我只知道TTS引擎可以自己写，Voice Recognize就不知道了，不过利用Android提供的API就很容易了，API demo有示例，很简单。但如果用原生ROM可以直接开发，要是用第三方ROM就可能开发不了，需要先安装语音搜索，也就是语音识别的引擎，因为很多ROM制造团队删除了语音识别引擎
