C#实现文本生成音频文件并播放

news2024/11/16 19:52:31

本文将使用C#实现一个简单的winfrom窗体应用程序，可以自定义文本转换为声音进行播放，生成音频文件。采用Microsoft提供的SpeechSynthesizer类来实现这个功能。

首先需要在代码中引用System.Speech.Synthesis命名空间，就可以使用SpeechSynthesizer类。

using System.Speech.Synthesis;

一、播放文本

public void play(string text)
{
    try
    {
        System.Threading.Thread.Sleep(500);
        WriteLogs("文本：" + text);
        if (text == "")
        {
            MessageBox.Show("请输入音频文本");
            return;
        }
        SpeechSynthesizer synth = new SpeechSynthesizer();
        PromptBuilder pb = new PromptBuilder();
        pb.AppendText(text);
        synth.Speak(pb);
        MessageBox.Show("播放成功");
    }
    catch (Exception e)
    {
        WriteLogs("播放失败：" + e.Message);
        MessageBox.Show("播放失败：" + e.Message);
    }
}

二、播放路径

public void playFile(string filename)
{
    try
    {
        System.Threading.Thread.Sleep(500);
        if (filename == "")
        {
            MessageBox.Show("请输入音频路径");
            return;
        }
        SoundPlayer player = new SoundPlayer();
        player.SoundLocation = filename;
        player.Load();//加载
        player.Play();//播放
        MessageBox.Show("播放成功");
    }
    catch (Exception e)
    {
        MessageBox.Show("播放失败：" + e.Message);
    }
}

三、生成音频

public void save(string text, string filename)
{
    try
    {
        System.Threading.Thread.Sleep(500);
        if (text == "")
        {
            MessageBox.Show("请输入音频文本");
            return;
        }
        else if (filename == "")
        {
            MessageBox.Show("请输入音频路径");
            return;
        }
        string file = filename.Substring(0, filename.LastIndexOf('/'));
        bool flag= !Directory.Exists(file);
        if (flag)
        {
            Directory.CreateDirectory(file);
        }
        SpeechSynthesizer synth = new SpeechSynthesizer();
        PromptBuilder pb = new PromptBuilder();
        pb.AppendText(text);
        synth.GetInstalledVoices().ToList().ForEach(voice => Console.WriteLine(voice.VoiceInfo.Name));
        synth.SelectVoice("Microsoft Huihui Desktop");
        // 设置合成音频的格式
        synth.SetOutputToWaveFile(filename, new SpeechAudioFormatInfo(8000, AudioBitsPerSample.Sixteen, AudioChannel.Mono));
        synth.Speak(pb);
        MessageBox.Show("生成成功");
    }
    catch (Exception e)
    {
        MessageBox.Show("生成失败：" + e.Message);
    }
}
