借助百度api,用python实现. 思路 使用python录音并保存为文件 调用api,得到识别结果 根据结果打开对应url 只贴了关键代码,完整代码请移步:https://github.com/missyoursmile/Command-a-computer-with-sound #定义命令字典(不知道为何百度会识别成这样,牛客识别不出来,用了部分识别) url_dict = { u'ｂａｉｄｕ': "https://www.baidu.com", u'牛': "https://www.nowcoder.com" } #录音并保存到文件(在另外一个文件中) wavfile = record_wave() #获取token access_token = requests.post(auth_url).json()['access_token'] res = None with open(wavfile,'rb') as f: r = requests.post(api_url+access_token, headers={'Content-Type': "audio/wav;rate=8000"}, data=f) res = r.json() if res['err_no'] != 0: #识别错误 res = None if not res: print "识别错误" exit() open_url = None for k in url_dict: if k in res['result'][0]: open_url = url_dict[k] print "识别结果: ",res['result'][0] if not open_url: print "没有对应的命令." exit() #调用系统命令,打开浏览器 os.system("explorer "+ open_url) 注意 只实现了Windows平台,其他平台请自行修改最后的系统调用 部分词汇可能难以识别,使用了部分匹配 公开了api key, 方便大家使用,请不要滥用,谢谢 如有好的离线语音识别库,请告诉我

科大讯飞的语音听写包，读入文件都省去了，内部直接调用了系统的录音功能，太强大了 都是开发包的功劳啊~~，感觉自己什么都没有做，惭愧............ 工具类 package iflytekTest; import com.iflytek.cloud.speech.*; import java.io.IOException; public class SpeechLisAndWrite { private static StringBuffer mResult = new StringBuffer(); public static String res = ""; public static void Recognize() { if (SpeechRecognizer.getRecognizer() == null) SpeechRecognizer.createRecognizer(); SpeechRecognizer mIat = SpeechRecognizer.getRecognizer(); // 设置听写参数 mIat.setParameter(SpeechConstant.DOMAIN, "iat"); mIat.setParameter(SpeechConstant.LANGUAGE, "zh_cn"); mIat.setParameter(SpeechConstant.ACCENT, "mandarin"); mIat.setParameter( SpeechConstant.RESULT_TYPE, "plain" ); // 开始监听 mIat.startListening(mListenser); // 需要等待语音识别结果 try { Thread.sleep(5000); } catch (InterruptedException e) { e.printStackTrace(); } // 调用命令打开百度 if(res.equals("百度。")) { try { // rundll32 url.dll,FileProtocolHandler 表示打开默认浏览器 // 可换成 cmd /c start iexplore 表示打开IE String url = "http://www.baidu.com"; Runtime.getRuntime().exec("rundll32 url.dll,FileProtocolHandler " + url); } catch (IOException e) { e.printStackTrace(); } } } private static RecognizerListener mListenser = new RecognizerListener() { public void onVolumeChanged(int i) { } public void onBeginOfSpeech() { System.out.println("开始听写"); } public void onEndOfSpeech() { System.out.println("结束听写"); } public void onResult(RecognizerResult recognizerResult, boolean b) { mResult.append(recognizerResult.getResultString()); if(b) { res += mResult.toString(); System.out.println(res); } } public void onError(SpeechError speechError) { } public void onEvent(int i, int i1, int i2, String s) { } }; } 启动类 package iflytekTest; import com.iflytek.cloud.speech.SpeechUtility; public class SpeechLisAndWriteTest { private static final String APPID = "XXXXXX"; // 这里改成自己的 public static void main(String[] args) { SpeechUtility.createUtility("appid=" + APPID); SpeechLisAndWrite.Recognize(); } }

求个java版的

去年的工作就是做这个，智能语音鼠标

不会
