说明:
(1)支持Window 7系统,但是xp系统智能朗读英文和数字;
(2)添加引用 Interop.SpeechLib.dll;
(3)使用时调用StringToVoice(str)即可。
using SpeechLib;
   /// <summary>
        /// 把字符串转换成声音
        /// </summary>
        /// <param name="str">要朗读的字符串</param>
        public static void StringToVoice(string str) {           
                if (str.Trim().Length > 0) {
                    SpVoiceClass svc = new SpVoiceClass();
                    SpeechVoiceSpeakFlags spFlags = SpeechVoiceSpeakFlags.SVSFlagsAsync;
                    svc.Speak(str, spFlags);
                }图示:
(1)后台代码
(2)运行效果
