Detailed explanation of the example of C# implementing voice broadcasting function

Voice broadcasting in C# usually requires using a voice library or service in the .NET Framework. A common option is to use the SpeechSynthesizer class in the namespace, which provides text-to-speech conversion.

Here is a simple example showing how to use SpeechSynthesizer for voice broadcasting in C#:

using System;
using ;
 
class Program
{
    static void Main()
    {
        // Create SpeechSynthesizer instance        using (SpeechSynthesizer synth = new SpeechSynthesizer())
        {
            // Set the voice synthesis engine            (, );
 
            // Broadcast message text            string textToSpeak = "Hello, this is a test. I am speaking in C#.";
            (textToSpeak);
 
            ("Speech completed.");
        }
    }
}

Please make sure that the assembly is referenced in your project. You can add a reference in Visual Studio by right-clicking on the project -> Add -> Reference -> Assembly -> Framework -> .

Note: It is not a default supported library in .NET Core. If your project is based on .NET Core, consider using other third-party voice synthesis libraries, such as the SDK or other available libraries.

Use the Cognitive Services Speech SDK for voice broadcast:

Install the NuGet package: Install the NuGet package in your project. You can do this in Visual Studio by right-clicking on the project -> Add -> NuGet Package Manager -> Manage NuGet Packages.

Use Speech SDK for voice broadcast: In the code, you can use the following method:

using System;
using ;
using ;
 
class Program
{
    static async Task Main()
    {
        // Replace with your Cognitive Services Speech API key and zone        var apiKey = "YourSpeechApiKey";
        var region = "YourSpeechApiRegion";
 
        var config = (apiKey, region);
        using var synthesizer = new SpeechSynthesizer(config);
 
        // Broadcast message text        var textToSpeak = "Hello, this is a test. I am speaking in .NET Core.";
        var result = await (textToSpeak);
 
        if ( == )
        {
            ("Speech completed.");
        }
        else
        {
            ($"Speech synthesis failed: {}");
        }
    }
}

Make sure to replace YourSpeechApiKey and YourSpeechApiRegion for the actual key and region of your Cognitive Services Speech API.

This example uses asynchronous operations, so the Main method is declared as async Task. Please note that using cloud services requires a network connection and may involve usage costs, depending on your usage.

Method 1

1. First, install the voice package Microsoft Speech SDK 5.1

2. Quote

3. Then the following code is

SpeechVoiceSpeakFlags flag = ;
SpVoice voice = new SpVoice();
 = 1;//Speech speed = 100;//volume = (, ).Item(0);//Item(0) Chinese, Item(3) English("Voice broadcast", flag);

Method 2

 List&lt;string&gt; ls_speack = new List&lt;string&gt;();
 
 
   public void Speaking()
    {
        Task task = new Task(() =&gt;
        {
            while (true)
            {
                (100);
                if (ls_speack.Count == 0)
                {
                    continue;
                }
                SpeechSynthesizer speech = new SpeechSynthesizer();
                 = 100; //volume                CultureInfo keyboardCulture = ;
                InstalledVoice neededVoice = (keyboardCulture).FirstOrDefault();
                if (neededVoice == null)
                {
                    //say = "Unknown operation";                }
                else
                {
                    ();
                }
                for (int k = 0; k &lt; ls_speack.Count; k++)
                {
                    (100);
                    (ls_speack[k]);
                }
                ls_speack = new List&lt;string&gt;();
            }
 
        });
        ();
    }
 
 
    public static void Speaking(string saying)
    {
        string say = saying;
        Task task = new Task(() =&gt;
        {
            SpeechSynthesizer speech = new SpeechSynthesizer();
             = 100; //volume            CultureInfo keyboardCulture = ;
            InstalledVoice neededVoice = (keyboardCulture).FirstOrDefault();
            if (neededVoice == null)
            {
                say = "Unknown operation";
            }
            else
            {
                ();
            }
 
            (say);
        });
        ();
    }
