C# 使用DotNetSpeech.dll实现文本朗读

//获取选择的速度
private int GetSpeedSelected()
{
if (rbtnFast.Checked) { return 2; }
if (rbtnNomal.Checked) { return 0; }
if (rbtnSlow.Checked) { return -3; }
return 0;
}

//阅读函数
private void Read(string text)
{
SpVoice sp = new SpVoice();
sp.Rate = GetSpeedSelected();
SpeechVoiceSpeakFlags sFlags = SpeechVoiceSpeakFlags.SVSFlagsAsync;
sp.Speak(text, sFlags);
}

private void btnRead_Click(object sender, EventArgs e)
{
if (string.IsNullOrEmpty(txtContent.Text))
Read("请输入需要朗读的文本");
else
Read(txtContent.Text);
}
