我目前正在用C#开发一个实现Text-To-Speech的小程序。但是,我发现可以使用两个名称空间:


系统语音合成
微软语音合成


我用谷歌搜索了差异,并找到了关于语音识别的this帖子。它并不能真正回答我的问题。我也在两者之间切换,没有区别。它适用于代码中的所有语言(如下)。

using System;
using System.Speech.Synthesis;
//using Microsoft.Speech.Synthesis;

namespace TTS_TEST
{
class Program
{

    static void Main(string[] args)
    {
          SpeechSynthesizer synth = new SpeechSynthesizer();

          int num;
          string userChoice;

          do
          {
             Console.WriteLine("1 - " + "Microsoft Server Speech Text to Speech Voice (en-US, ZiraPro)");
             Console.WriteLine("2 - " + "Microsoft Server Speech Text to Speech Voice (en-GB, Hazel)");
             Console.WriteLine("3 - " + "Microsoft Server Speech Text to Speech Voice (es-ES, Helena)");
             Console.WriteLine("4 - " + "Microsoft Server Speech Text to Speech Voice (fr-FR, Hortense)");
             Console.WriteLine("5 - " + "Exit");
             Console.Write("Enter the number of your choice: ");     //the user chooses a number
             userChoice = Console.ReadLine();

             if (!Int32.TryParse(userChoice, out num)) continue;

             Console.WriteLine("Choice = " + userChoice);

             if (userChoice == "1")    //Option 1 will use the voice en-US, ZiraPro
             {
                synth.SelectVoice("Microsoft Server Speech Text to Speech Voice (en-US, ZiraPro)");
             }

             if (userChoice == "2")   //Option 2 will use the voice en-GB, Hazel
             {
                synth.SelectVoice("Microsoft Server Speech Text to Speech Voice (en-GB, Hazel)");
             }

             if (userChoice == "3")   //Option 3 will use the voice es-ES, Helena
             {
                synth.SelectVoice("Microsoft Server Speech Text to Speech Voice (es-ES, Helena)");
             }

             if (userChoice == "4")   //Option 4 will use the voice fr-FR, Hortense
             {
                synth.SelectVoice("Microsoft Server Speech Text to Speech Voice (fr-FR, Hortense)");
             }

             if (userChoice == "5")   //Option 5 will exit application
             {
                Environment.Exit(0);
             }

             synth.SetOutputToDefaultAudioDevice();   //set the default audio output

             foreach (InstalledVoice voice in synth.GetInstalledVoices())   //list the installed voices details
             {
                VoiceInfo info = voice.VoiceInfo;

                Console.WriteLine(" Name:          " + info.Name);
                synth.Speak("Name: " + info.Name);
                Console.WriteLine(" Culture:       " + info.Culture);
                synth.Speak("Culture: " + info.Culture);
                Console.WriteLine(" Age:           " + info.Age);
                synth.Speak("Age: " + info.Age);
                Console.WriteLine(" Gender:        " + info.Gender);
                synth.Speak("Gender: " + info.Gender);
                Console.WriteLine(" Description:   " + info.Description);
                Console.WriteLine(" ID:            " + info.Id + "\n");
                synth.Speak("ID: " + info.Id);
             }

             Console.ReadKey();

          }
          while (true);
    }
  }
}


有人可以解释一下两者之间的区别吗?

最佳答案

差异实际上与链接的答案大致相同。 System.Speech.SpeechSynthesis使用桌面TTS引擎,而Microsoft.Speech.SpeechSynthesis使用服务器TTS引擎。从编程的角度来看,差异相对较小,但从许可的角度来看,则存在很大差异;服务器TTS引擎是单独许可的。

但是,System.Speech.SpeechSynthesisMicrosoft.Speech.SpeechSynthesis都是不推荐使用的API,并且新开​​发应基于Windows.Media.SpeechSynthesis API。

关于c# - System.Speech.Synthesis和Microsoft.Speech.Synthesis有什么区别?,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/54554350/
