c#科大讯飞离线语音合成与在线语音合成 在一个winform程序中需要集成语音合成的功能，再三斟酌后还是选了科大讯飞，然后就对科大讯飞的语音合成模块进行简单的封装了一下；此类包含科大讯飞在线语音合成、离线语音合成功能的简单封装，首先在科大讯飞平台选择SDK功能（需要注意的是离线语音合成在不付费的情况下仍有90天的试用时长，这点很不错）。{message type="error" content="注意：本例子使用x86的类库，所以项目编译平台应是改为x86才能正常运行。"/}{dotted startColor="#ff6c6c" endColor="#1989fa"/}选择完SDK能力后，下载SDK文件包；SDK包解压将bin目录下的msc.dll与msc_x64.dll复制到程序运行目录下。将bin>src>res>下的tts整个文件夹复制到程序运行目录下（如果有离线语音合成能力的话）using CiCommon; using System; using System.Collections.Generic; using

c#使用百度语音合成教程 简介最近有个程序需要用到语音识别即文字转语音功能，但是是需要离线模式下使用，经过再三的斟酌；还是选用了科大讯飞的离线语音合成库。既然研究了百度语音合成调用那就放上来给大家做个参考，目前只尝试了在线语音合成离线语音合成暂时没弄；改天有机会再弄弄吧，科大讯飞的语音合成调用就放到下篇文章吧。首先Nuget中安装 百度AIusing Baidu.Aip.Speech; using DevComponents.DotNetBar; using NAudio.Wave; using System; using System.Collections.Generic; using System.IO; using System.Linq; using System.Runtime.InteropServices; using System.Text; using System.Windows.Forms; namespace Text2Voice.VOICESDK { class BaiduSDK { private readonly Asr _asrClient; private readonly Tts _ttsClient; public BaiduSDK() { _asrClient = new Asr("appId", "apiKey", "secretKey"); _ttsClient = new Tts("apiKey", "secretKey"); } // 识别本地文件 public void AsrData() { var data = File.ReadAllBytes("语音pcm文件地址"); var result = _asrClient.Recognize(data, "pcm", 16000); Console.Write(result); } // 识别URL中的语音文件 public void AsrUrl() { var result = _asrClient.Recognize( "http://xxx.com/待识别的pcm文件地址", "http://xxx.com/识别结果回调地址", "pcm", 16000); Console.WriteLine(result); } // 合成 public void Tts(string content, ref byte[] bte, bool isSave = false, int spd = 4, int vol = 5, int per = 4) { try { // 可选参数 var option = new Dictionary<string, object>() { {"spd", spd}, // 语速 {"vol", vol}, // 音量 {"per", per} // 发音人，4：情感度丫丫童声 }; var result = _ttsClient.Synthesis(content, option); if (result.ErrorCode == 0) // 或 result.Success { WaveOut waveOut = new WaveOut(); MemoryStream mStream = new MemoryStream(result.Data); Mp3FileReader rdr = new Mp3FileReader(mStream); bte = result.Data; var wavStream = WaveFormatConversionStream.CreatePcmStream(rdr); var baStream = new BlockAlignReductionStream(wavStream); waveOut = new WaveOut(WaveCallbackInfo.FunctionCallback()); waveOut.Init(baStream); waveOut.Stop(); waveOut.Play(); } } catch (Exception ex) { MessageBoxEx.Show("语音引擎初始化失败!", "错误", MessageBoxButtons.OK, MessageBoxIcon.Warning); throw ex; } } } public enum BaiduSpeaker { 青年女生 = 0, 青年男生 = 1, 度逍遥 = 3, 度丫丫 = 4 } } 调用示例BaiduSDK sdk = new BaiduSDK(); //语速设置 int spd = cboSpeed.SelectedIndex; //声音设置 int vol = cboVol.SelectedIndex; //发音人设置 var per = Enum.Parse(typeof(BaiduSpeaker), cboPerson.Text); sdk.Tts(txtContent.Text, ref bte, isSave, spd, vol, (int)per);
