speech-recognition - Microsoft.Speech.Synthesis 不适用于文本转语音但 System.Speech.Synthesis 有效。为什么？

Question

我只是尝试使用 Microsoft.Speech.dll;

为文本转语音运行简单的 Microsoft 示例

using System;
using Microsoft.Speech.Synthesis;

namespace TTS
{
    class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Testing TTS!");

            // Initialize a new instance of the SpeechSynthesizer.
            using (SpeechSynthesizer synth = new SpeechSynthesizer())
            {

                // Output information about all of the installed voices.
                Console.WriteLine("Installed voices -");
                foreach (InstalledVoice voice in synth.GetInstalledVoices())
                {
                    VoiceInfo info = voice.VoiceInfo;
                    Console.WriteLine(" Voice Name: " + info.Name);
                }

                // Select the US English voice.
                synth.SelectVoice("Microsoft Server Speech Text to Speech Voice (en-GB, Hazel)");

                // Build a prompt.
                PromptBuilder builder = new PromptBuilder();
                builder.AppendText("That is a big pizza!");

                // Speak the prompt.
                synth.Speak(builder);
            }

            Console.Write("Press any key to continue . . . ");
            Console.ReadKey(true);
        }
    }
}

虽然我有正确的声音，但它没有发出任何声音。没有文字转语音 (TTS) 语音。

当我使用 Microsoft System.Speech.dll 时，我可以听到声音。所以没有声音问题。

using System;
using System.Speech.Synthesis;

namespace TTS
{
    class Program
    {
        public static void Main(string[] args)
        {
            Console.WriteLine("Testing TTS!");

            // Initialize a new instance of the SpeechSynthesizer.
            using (SpeechSynthesizer synth = new SpeechSynthesizer())
            {

                // Output information about all of the installed voices.
                Console.WriteLine("Installed voices -");
                foreach (InstalledVoice voice in synth.GetInstalledVoices())
                {
                    VoiceInfo info = voice.VoiceInfo;
                    Console.WriteLine(" Voice Name: " + info.Name);
                }

                // Build a prompt.
                PromptBuilder builder = new PromptBuilder();
                builder.AppendText("That is a big pizza!");

                // Speak the prompt.
                synth.Speak(builder);
            }

            Console.Write("Press any key to continue . . . ");
            Console.ReadKey(true);
        }
    }
}

Why I can not hear any voice or make Text To Speech(TTS) with Microsoft Speech Platform using Microsoft.Speech? Should I do some extra config?

Answer 1

因为您使用的是两个不同的 TTS 引擎。 Microsoft.Speech 使用服务器 TTS 语音； System.Speech 使用桌面 TTS 语音。查看讨论 here .

Windows Vista 及更高版本默认注册桌面 TTS 语音，但没有服务器 TTS 语音。当您安装 Server Speech Platform Runtime ，我相信您必须这样做才能首先加载 Microsoft.Speech.dll，您还应该可以选择安装一些服务器 TTS 语音。
