以下是使用科大讯飞离线语音合成的C#代码示例:
```C#
using System;
using System.IO;
using System.Runtime.InteropServices;
using System.Text;
namespace IFlyTekCoVoice
{
class Program
{
// 初始化
[DllImport("msc.dll", CallingConvention = CallingConvention.StdCall)]
public static extern int MSPLogin(string usr, string pwd, string parameters);
// 文本合成语音
[DllImport("msc.dll", CallingConvention = CallingConvention.StdCall)]
public static extern IntPtr QTTSSessionBegin(string _params, ref int errorCode);
// 文本输入
[DllImport("msc.dll", CallingConvention = CallingConvention.StdCall)]
public static extern int QTTSTextPut(string sessionID, string textString, uint textLen, string paramsString);
// 语音输出
[DllImport("msc.dll", CallingConvention = CallingConvention.StdCall)]
public static extern IntPtr QTTSAudioGet(string sessionID, ref uint audioLen, ref int synthStatus, ref int errorCode);
// 结束会话
[DllImport("msc.dll", CallingConvention = CallingConvention.StdCall)]
public static extern int QTTSSessionEnd(string sessionID, string hints);
// 退出登录
[DllImport("msc.dll", CallingConvention = CallingConvention.StdCall)]
public static extern int MSPLogout();
static void Main(string[] args)
{
// 登录科大讯飞
int ret = MSPLogin("", "", "appid = 12345678, work_dir = .");
if (ret != 0)
{
Console.WriteLine("登录失败,错误码:" + ret);
return;
}
// 初始化参数
string sessionBeginParams = "engine_type = local, voice_name = xiaoyan, text_encoding = utf8, tts_res_path = fo|res\\tts\\xiaoyan.jet;";
int errorCode = 0;
// 开始会话
IntPtr sessionID = QTTSSessionBegin(sessionBeginParams, ref errorCode);
if (errorCode != 0)
{
Console.WriteLine("开始会话失败,错误码:" + errorCode);
MSPLogout();
return;
}
// 输入文本
string textString = "科大讯飞离线语音合成示例";
uint textLen = (uint)Encoding.UTF8.GetByteCount(textString);
ret = QTTSTextPut(sessionID, textString, textLen, null);
if (ret != 0)
{
Console.WriteLine("文本输入失败,错误码:" + ret);
QTTSSessionEnd(sessionID, "");
MSPLogout();
return;
}
// 输出语音
uint audioLen = 0;
int synthStatus = 0;
IntPtr audioData = QTTSAudioGet(sessionID, ref audioLen, ref synthStatus, ref errorCode);
if (errorCode != 0)
{
Console.WriteLine("语音输出失败,错误码:" + errorCode);
QTTSSessionEnd(sessionID, "");
MSPLogout();
return;
}
// 保存语音文件
byte[] audioBuffer = new byte[audioLen];
Marshal.Copy(audioData, audioBuffer, 0, (int)audioLen);
using (FileStream fileStream = new FileStream("output.wav", FileMode.Create))
{
fileStream.Write(audioBuffer, 0, (int)audioLen);
}
// 结束会话
QTTSSessionEnd(sessionID, "");
// 退出登录
MSPLogout();
Console.WriteLine("语音合成完成");
}
}
}
```
请注意:在使用该示例代码前,需要先在科大讯飞官网申请开发者账号并创建应用,获取AppID,以及下载并安装离线语音合成SDK。
