在android应用中加入语音功能，将使应用更加的实用、方便。google的语音使用还是比较简单的，下面给大家介绍一下使用方法：

1、下载Google Voice的APK安装包，在手机中进行安装。

2、Android调用Google Voice代码

private static final int RESULT_FROM_VOICE = 1;

(1) 启动谷歌语音

/** * 启动谷歌语音 */private void startGoogleVoice() {try{Intent intent = new Intent(RecognizerIntent.ACTION_RECOGNIZE_SPEECH);        intent.putExtra(RecognizerIntent.EXTRA_LANGUAGE_MODEL,                RecognizerIntent.LANGUAGE_MODEL_FREE_FORM);        intent.putExtra(RecognizerIntent.EXTRA_PROMPT, "开始语音");        startActivityForResult(intent, RESULT_FROM_VOICE);}catch(ActivityNotFoundException e){// 下载谷歌语音APK包，并安装。FileDownload fd = new FileDownload(ExpressActivity.this, ConstData.googleVoiceUrl, "下载谷歌语音引擎");fd.showDownloadNoticeDialog();}    }

(2)接收返回值

重写Activity的onActivityResult方法

//返回值@Overrideprotected void onActivityResult(int requestCode, int resultCode, Intent data) {if(data == null)return;//谷歌语音if(requestCode == RESULT_FROM_VOICE){ matches = data.getStringArrayListExtra( RecognizerIntent.EXTRA_RESULTS); if(matches != null && matches.size() > 0){ Dialog dialog = new GoogleVoiceDialog(ExpressActivity.this,                     R.style.GoogleVoiceDialog);             dialog.show(); }}super.onActivityResult(requestCode, resultCode, data);}
