web个性化，web版tts语音合成技术，cs架构语音合成技术，web时时推送技术，异步调用多线程技术

我本人亲自实现了一个web版本的tts语音合成技术，和cs版本的tts语音合成技术

这个是后台源码

/// <summary>

/// 发送HTTP请求

/// </summary>

/// <param name="url">请求的URL</param>

/// <param name="param">请求的参数</param>

/// <returns>请求结果</returns>

public string request(string url, string param)

{

url = "http://apis.baidu.com/apistore/baidutts/tts";

param = "text=heloyuzhilinctp=1&per=0";

string strURL = url + '?' + param;

System.Net.HttpWebRequest request;

request = (System.Net.HttpWebRequest)WebRequest.Create(strURL);

request.Method = "GET";

// 添加header

request.Headers.Add("apikey", "c5682670452c7aeee370ee1b09e24e79");

System.Net.HttpWebResponse response;

response = (System.Net.HttpWebResponse)request.GetResponse();

System.IO.Stream s;

s = response.GetResponseStream();

string StrDate = "";

string strValue = "";

StreamReader Reader = new StreamReader(s, Encoding.UTF8);

while ((StrDate = Reader.ReadLine()) != null)

{

strValue += StrDate + "\r\n";

}

return strValue;

}

web版本的tts语音合成技术，我采用的方法是直接调用百度的接口，直接返回一个base64格式的编码，直接播放就可以了，

cs版本我就不过多的介绍了，网上都能找得到

public static void systemspeech(object word, int kanumber)

{

try

{

SpeechVoiceSpeakFlags spFlags = SpeechVoiceSpeakFlags.SVSFlagsAsync;

SpVoice voice = new SpVoice();

SpeechStreamFileMode spFileMode = SpeechStreamFileMode.SSFMCreateForWrite;

SpFileStream spFileStream = new SpFileStream();

SpAudioFormat SpAudio = new DotNetSpeech.SpAudioFormat();

SpAudio.Type = SpeechAudioFormatType.SAFT48kHz16BitStereo;

var XmlFilePath = Guid.NewGuid().ToString();

spFileStream.Format = SpAudio;

//XmlFilePath = System.Windows.Forms.Application.StartupPath + "/video/" + XmlFilePath + ".wav";System.AppDomain.CurrentDomain.BaseDirectory + "Style\\Images";

// XmlFilePath = System.AppDomain.CurrentDomain.BaseDirectory + "Style\\voice\\" + Voiceprompt + ".wav";

XmlFilePath = System.AppDomain.CurrentDomain.BaseDirectory + "Style\\voice\\Voicepromptr.wav";

//XmlFilePath = System.AppDomain.CurrentDomain.BaseDirectory + ".\\voice\\Voiceprompt.wav";

spFileStream.Open(XmlFilePath, spFileMode, false);

voice.AudioOutputStream = spFileStream;

voice.Speak(word.ToString(), spFlags);

voice.WaitUntilDone(Timeout.Infinite);

spFileStream.Close();

}

catch

{

}

}

//读取文件

/// <summary>

/// 输出WAV

/// </summary>

/// <param name="path">保存路径</param>

/// <param name="str">要转换的文本内容</param>

/// <returns></returns>

public bool WreiteToWAV(string path, string str, SpeechAudioFormatType SpAudioType)

{

SpeechStreamFileMode SpFileMode = SpeechStreamFileMode.SSFMCreateForWrite;

SpVoice voice = new SpVoice();

SpFileStream SpFileStream = new SpFileStream();

SpeechVoiceSpeakFlags SpFlags = SpeechVoiceSpeakFlags.SVSFlagsAsync;

SpAudioFormat SpAudio = new DotNetSpeech.SpAudioFormat();

SpAudio.Type = SpAudioType;

SpFileStream.Format = SpAudio;

SpFileStream.Open(path, SpFileMode, false);

voice.AudioOutputStream = SpFileStream;

voice.Speak(str, SpFlags);

// voice.AudioOutputStream.Format.Type = SpeechAudioFormatType.SAFT48kHz16BitStereo;

voice.WaitUntilDone(Timeout.Infinite);

SpFileStream.Close();

return File.Exists(path);

}

public void read_Word(object word)

{

try

{

SpeechVoiceSpeakFlags SpFlags = SpeechVoiceSpeakFlags.SVSFlagsAsync;

SpVoice Voice = new SpVoice();

Voice.Voice = Voice.GetVoices(string.Empty, string.Empty).Item(2);

//ISpeechObjectTokens sb = Voice.GetVoices("", "");

//foreach (ISpeechObjectToken so in sb)

// Voice.Voice = Voice.GetVoices("name=Microsoft Lili", "").Item(0);

Voice.Rate = 4;

Voice.Volume = 80;

Voice.Speak(word.ToString(), SpFlags);

}

catch (System.Exception ec)

{

MessageBox.Show(ec.ToString(), "SpeechApp", MessageBoxButtons.OK, System.Windows.Forms.MessageBoxIcon.Error);

//syth.SelectVoice("Microsoft Server Speech Text to Speech Voice (zh-CN, HuiHui)");

////syth.SelectVoice("Microsoft Anna");

//string fileFullPath = @"E:\项目备份\LCMS_Comac\Pelesys.LCMS.Web\CBTUnitFiles\Cu02161\MediaFiles\123.wav"; // TODO: Initialize to an appropriate value

//syth.SetOutputToWaveFile(fileFullPath);

//syth.Rate = 0;

//syth.Speak("sdfwod项目备份sdfsdf");

}

}

高并发高性能， frid 时时读取最新数据并推送到html5页面或者pc端页面 web页面推送技术源码

前台页面源码

<script type="text/javascript">

$(function () {

(function longPolling() {

$.ajax({

url: "/WebSocket/indexstring",

data: { "timed": new Date().getTime() },

dataType: "text",

cache: false, //无缓存

timeout: 5000,

error: function (XMLHttpRequest, textStatus, errorThrown) {

$("#state").append("[state: " + textStatus + ", error: " + errorThrown + " ]<br/>");

if (textStatus == "timeout") { // 请求超时

longPolling(); // 递归调用

// 其他错误，如网络错误等

} else {

longPolling();

}

},

success: function (data, textStatus) {

$("#state").append("[state: " + textStatus + ", data: { " + data + "} ]<br/>");

if (textStatus == "success") { // 请求成功

longPolling();

}

}

});

})();

});

</script>

后台源码：

/*************/

//LongPolling Action 1 - 处理客户端发起的请求

public void LongPollingAsync()

{

//计时器，5秒种触发一次Elapsed事件

System.Timers.Timer timer = new System.Timers.Timer(2000);

//告诉ASP.NET接下来将进行一个异步操作

AsyncManager.OutstandingOperations.Increment();

//订阅计时器的Elapsed事件

timer.Elapsed += (sender, e) =>

{

//保存将要传递给LongPollingCompleted的参数

AsyncManager.Parameters["now"] = e.SignalTime;

//告诉ASP.NET异步操作已完成，进行LongPollingCompleted方法的调用

AsyncManager.OutstandingOperations.Decrement();

};

//启动计时器

timer.Start();

}

不是最新代码，最新代码融合了异步调用，回调函数，socket通讯
