C#实现语音朗读功能

引用类库:System.Speech.dll

导入空间:

using System.Speech.Synthesis; //用于生成响应的事件
using System.Speech;
using System.Speech.Recognition;

//1.Async="true"

//2.SpeechSynthesizer speak = new SpeechSynthesizer();

//同步朗读
//3.1 speak.Speak(txt.Text.Trim());
//speak.Dispose();  //释放之前的资源

//异步朗读
//3.2 speak.SpeakAsync(txt.Text.Trim());

//speak.Volume = 100;  //设置朗读音量 [范围 0 ~ 100] 
//speak.Rate = 0;      //设置朗读频率 [范围  -10 ~ 10] 
//speak.SelectVoice("Microsoft Lili");  //SpeakChina
//speak.SelectVoice("Microsoft Anna");  //SpeakEnglish
//SelectVoiceByHints(VoiceGender.Male, VoiceAge.Child, 2, System.Globalization.CultureInfo.CurrentCulture);
//speak.SpeakAsyncCancelAll();  //取消朗读
//speak.SetOutputToWaveFile("c:\\message.wav");

//语音合成
//4.PromptBuilder pb = new PromptBuilder();
//speak.SelectVoice("Microsoft Lili");
//pb.ClearContent();

//.Net 4.0 的实现方式: 
/*
    Type type = Type.GetTypeFromProgID("SAPI.SpVoice");
    dynamic spVoice = Activator.CreateInstance(type);
    spVoice.Speak("你好,欢迎使用 CSharp 4.0!");
    */

//5.语音完成
/*
    speak.SpeakCompleted += new EventHandler<SpeakCompletedEventArgs>(speak_SpeakCompleted);
    void speak_SpeakCompleted(object sender, SpeakCompletedEventArgs e)
    {
    txt.Text = "完成";
    }
    */

//SPEAK 开始 
/*var reader = new SpeechSynthesizer();
reader.SpeakAsync(txt.Text); */

//event handler 
//reader.SpeakCompleted += new EventHandler<SpeakCompletedEventArgs>(reader_SpeakCompleted);
//或
//sp.SpeakCompleted += (s, arg) => txt.Text = "true";

//PAUSE 暂停
/*if (reader.State == SynthesizerState.Speaking)
{
    reader.Pause();
    btn_pause.Text = "继续";
}*/

//RESUME 继续
/*if (reader.State == SynthesizerState.Paused)
{
    reader.Resume();
    btn_pause.Text = "暂停";
}*/

//STOP 停止
//reader.Dispose();
