基于C# 百度AI和科大汛飞语音合成SDK

标签:name base64 发送 root tts 界面 index second obj 百度语音合成C# SDK主要是基于Rest API,需要互联网调用HTTP接口,Rest API 仅支持最多512个汉字,合成的格式文件为MP3,没有其它的格式。如果想离线使用需下载SDK,Android 或IOS。 C# SDK 现已开源! https://github.com/Baidu-AIP/dotnet-sdk ** 支持平台:.Net Framework 3.5 4.0 4.5, .Net Core 2.0 ** 在NuGet中搜索 packet地址 https://www.nuget.org/packages/Baidu.AI/ 接口参数说明: 科大讯飞没有c# SDK,采用WebAPi的形式调用。不过请注意该接口使用的HTTP API协议不支持跨域。 注: 调用接口前需配置IP白名单,IP白名单规则请参照 IP白名单。(由于我之前没有设置正确的IP,导致接口调用不成功)可以在百度里面输入IP将会显示你的互联网IP 注: 在控制台添加服务后,点击“发音人管理”可自行添加并试用发音人,添加后会显示该发音人参数值,设置参数voice_name为相应的发音人参数值即可。 源代码 通过尝试百度和科大讯飞两个语音合成接口,发现科大讯飞语音比较好一些,百度有些词语会读错。 基于C# 百度AI和科大汛飞语音合成SDK 标签:name base64 发送 root tts 界面 index second obj 原文地址:https://www.cnblogs.com/w2011/p/11328023.html一、百度语音合成
1、安装语音合成 C# SDK
2、方法一:使用Nuget管理依赖 (推荐)
Baidu.AI
,安装最新版即可。3、源程序界面及代码
#region 百度语音
private void simpleButton1_Click(object sender, EventArgs e)
{
if (spinEdit1.Value 0)
{
spinEdit1.Focus();
return;
}
if (trackBarControl1.Value 0)
{
trackBarControl1.Focus();
return;
}
if (string.IsNullOrEmpty(textBox1.Text.Trim()))
{
textBox1.Focus();
textBox1.Select();
return;
}
// 设置APPID/AK/SK
var APP_ID = "******";
var API_KEY = "******";
var SECRET_KEY = "*****";
var client = new Baidu.Aip.Speech.Tts(API_KEY, SECRET_KEY);
client.Timeout = 60000; // 修改超时时间
// 可选参数
var option = new Dictionarystring, object>()
{
{"spd", spinEdit1.Value}, // 语速
{"vol", trackBarControl1.Value}, // 音量
{"per", comboBoxEdit1.SelectedIndex} // 发音人,4:情感度丫丫童声
};
var result = client.Synthesis(textBox1.Text, option);
if (xtraSaveFileDialog1.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{

{
File.WriteAllBytes(xtraSaveFileDialog1.FileName, result.Data);

1、接口调用流程
2、程序界面及源代码
