如何在 Google TTS 中输入 SSML？ （C＃）

Question

我一直在使用 Google 提供的示例 C# 代码来熟悉 Google TTS。我想输入 ssml，但我不知道该怎么做。如果有人能告诉我需要更改哪一行代码，我将不胜感激。

我尝试将下面的“文本”更改为“SSML”，但这不起作用。我也尝试在输入的文本中使用 SSML 标签，但这也不起作用。

我查看了相关的 Google SSML 文档，但我无法弄清楚我做错了什么。

using Google.Cloud.TextToSpeech.V1;
using System;
using System.IO;

namespace TextToSpeechApiDemo
{
class Program
{
    static void Main(string[] args)
    {
        var client = TextToSpeechClient.Create();

        // The input to be synthesized, can be provided as text or SSML.
        var input = new SynthesisInput
        {
            Text = "This is a demonstration of the Google Cloud Text-to-Speech API"
        };

        // Build the voice request.
        var voiceSelection = new VoiceSelectionParams
        {
            LanguageCode = "en-US",
            SsmlGender = SsmlVoiceGender.Female
        };

        // Specify the type of audio file.
        var audioConfig = new AudioConfig
        {
            AudioEncoding = AudioEncoding.Mp3
        };

        // Perform the text-to-speech request.
        var response = client.SynthesizeSpeech(input, voiceSelection, audioConfig);

        // Write the response to the output file.
        using (var output = File.Create("output.mp3"))
        {
            response.AudioContent.WriteTo(output);
        }
        Console.WriteLine("Audio content written to file \"output.mp3\"");
    }
}

}

解决方案非常简单。更改您的代码部分：

var input = new SynthesisInput
{
    Text = "This is a demonstration of the Google Cloud Text-to-Speech API"
};

到这里：

var input = new SynthesisInput
{
    Ssml = "<speak>This is a demonstration of the Google Cloud Text-to-Speech API.<break time=\"1s\"/>This API is very easy to use.<break time=\"1s\"/><say-as interpret-as=\"characters\">SSML</say-as>is also easy to use.</speak>"
};
