我用System.Speech.Synthesis做一個(gè)網(wǎng)絡(luò)語音合成的Webservice，服務(wù)端的代碼如下：[WebMethod]        public bool tts(string txt, string fileName)        {            bool result = false;            fileName = @"C:\Inetpub\NXUTTS\" + fileName;            Speach _speach = new Speach();            _speach.SelectVoice("VW Lily");            if (txt != string.Empty && fileName != string.Empty)            {                _speach.SpeakOutFile(txt, fileName);                result = true;            }            _speach.Dispose();            return result;        }運(yùn)行后，語音文件正常合成，但是新彈出的頁面一直假死，不結(jié)束。
