1.新建WinForm程序，项目名称命名为Speech.
2.在COM组件中添加SpeechLib的引用。
using SpeechLib;//添加语音引用
添加一个文本框并将其重命名为txtContent和两个按钮控件分别用做发音（btnRead）和保存(btnSave)，实现代码如下：
private void btnRead_Click(object sender, EventArgs e)
{
Speak(txtContent.Text);
}
private void Speak(string speak)
{
//char[] chars=speak.ToArray();
SpVoice voice = new SpVoice();
voice.Rate = -2;//朗读速度
voice.Voice = voice.GetVoices(string.Empty,string.Empty).Item(0);
//for (int i = 0; i < chars.Length; i++)
//{
// voice.Speak(chars[i].ToString(), SpeechVoiceSpeakFlags.SVSFDefault);
//}
voice.Speak(speak, SpeechVoiceSpeakFlags.SVSFDefault);
voice.Speak("完毕", SpeechVoiceSpeakFlags.SVSFDefault);
}
//保存语音
private void btnSave_Click(object sender, EventArgs e)
{
try
{
SpeechVoiceSpeakFlags SpFlags = SpeechVoiceSpeakFlags.SVSFlagsAsync;
SpVoice Voice = new SpVoice();
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "All files (*.*)|*.*|wav files (*.wav)|*.wav";
sfd.Title = "Save to a wave file";
sfd.FilterIndex = 2;
sfd.RestoreDirectory = true;
if (sfd.ShowDialog() == DialogResult.OK)
{
SpeechStreamFileMode SpFileMode = SpeechStreamFileMode.SSFMCreateForWrite;
SpFileStream SpFileStream = new SpFileStream();
SpFileStream.Open(sfd.FileName, SpFileMode, false);
Voice.AudioOutputStream = SpFileStream;
Voice.Speak(this.txtContent.Text, SpFlags);
Voice.WaitUntilDone(100);
SpFileStream.Close();
}
}
catch (Exception)
{
MessageBox.Show("An Error Occured!", "SpeechApp", MessageBoxButtons.OK, MessageBoxIcon.Error);
}
}
其中代码：
voice.Voice = voice.GetVoices(string.Empty,string.Empty).Item(0);
中0可以读取汉语和英语，而1只能读取英语，其他数字就报错，在网上也没找到合适答案，以后会继续修复现有问题。欢迎大神提出解决问题的办法
